but we can verify if the expected affinity is contained in the pod affinity.

 * Removal of maintainers from Velero
 
+## Deprecation Policy
+
+### Deprecation Process
+
+Any contributor may introduce a request to deprecate a feature or an option of a feature by opening a feature request issue in the vmware-tanzu/velero GitHub project. The issue should describe why the feature is no longer needed or has become detrimental to Velero, as well as whether and how it has been superseded. The submitter should give as much detail as possible.
+
+Once the issue is filed, a one-month discussion period begins. Discussions take place within the issue itself as well as in the community meetings. The person who opens the issue, or a maintainer, should add the date and time marking the end of the discussion period in a comment on the issue as soon as possible after it is opened. A decision on the issue needs to be made within this one-month period.
+
+The feature will be deprecated by a supermajority vote of 50% plus one of the project maintainers at the time of the vote tallying, which is 72 hours after the end of the community meeting that is the end of the comment period. (Maintainers are permitted to vote in advance of the deadline, but should hold their votes until as close as possible to hear all possible discussion.) Votes will be tallied in comments on the issue. 
+
+Non-maintainers may add non-binding votes in comments to the issue as well; these are opinions to be taken into consideration by maintainers, but they do not count as votes. 
+
+If the vote passes, the deprecation window takes effect in the subsequent release, and the removal follows the schedule. 
+
+### Schedule
+If depreciation proposal passes by supermajority votes, the feature is deprecated in the next minor release and the feature can be removed completely after two minor version or equivalent major version e.g., if feature gets deprecated in Nth minor version, then feature can be removed after N+2 minor version or its equivalent if the major version number changes.
+
+### Deprecation Window
+
+The deprecation window is the period from the release in which the deprecation takes effect through the release in which the feature is removed. During this period, only critical security vulnerabilities and catastrophic bugs should be fixed.
+
+**Note:** If a backup relies on a deprecated feature, then backups made with the last Velero release before this feature is removed must still be restorable in version `n+2`. For instance, something like restic feature support, that might mean that restic is removed from the list of supported uploader types in version `n` but the underlying implementation required to restore from a restic backup won't be removed until release `n+2`.

 Note that we do not currently consider the default settings for Velero to be secure-by-default. It is necessary for operators to explicitly configure settings, role based access control, and other resource related features in Velero to provide a hardened Velero environment. We will not act on any security disclosure that relates to a lack of safe defaults. Over time, we will work towards improved safe-by-default configuration, taking into account backwards compatibility.

@@ -51,7 +51,6 @@ To fix CVEs and keep pace with Golang, Velero made changes as follows:
 * Prior to v1.12, the parameter `uploader-type` for Velero installation had a default value of "restic". However, starting from this version, the default value has been changed to "kopia". This means that Velero will now use Kopia as the default path for file system backup.
 * The ways of setting CSI snapshot time have changed in v1.12. First, the sync waiting time for creating a snapshot handle in the CSI plugin is changed from the fixed 10 minutes into backup.Spec.CSISnapshotTimeout. The second, the async waiting time for VolumeSnapshot and VolumeSnapshotContent's status turning into `ReadyToUse` in operation uses the operation's timeout. The default value is 4 hours.
 * As from [Velero helm chart v4.0.0](https://github.com/vmware-tanzu/helm-charts/releases/tag/velero-4.0.0), it supports multiple BSL and VSL, and the BSL and VSL have changed from the map into a slice, and[ this breaking change](https://github.com/vmware-tanzu/helm-charts/pull/413) is not backward compatible. So it would be best to change the BSL and VSL configuration into slices before the Upgrade.
-* Prior to v1.12, deleting the Velero namespace would easily remove all the resources within it. However, with the introduction of finalizers attached to the Velero CR including `restore`, `dataupload`, and `datadownload` in this version, directly deleting Velero namespace may get stuck indefinitely because the pods responsible for handling the finalizers might be deleted before the resources attached to the finalizers. To avoid this issue, please use the command `velero uninstall` to delete all the Velero resources or ensure that you handle the finalizer appropriately before deleting the Velero namespace.

+

+
+### Upgrading
+https://velero.io/docs/v1.13/upgrade-to-1.13/
+
+### Highlights
+
+#### Resource Modifier Enhancement
+Velero introduced the Resource Modifiers in v1.12.0. This feature allows users to specify a ConfigMap with a set of rules to modify the resources during restoration. However, only the JSON Patch is supported when creating the rules, and JSON Patch has some limitations, which cannot cover all use cases. In v1.13.0, Velero adds new support for JSON Merge Patch and Strategic Merge Patch, which provide more power and flexibility and allow users to use the same ConfigMap to apply patches on the resources. More design details can be found in [Support JSON Merge Patch and Strategic Merge Patch in Resource Modifiers](https://github.com/vmware-tanzu/velero/blob/main/design/Implemented/merge-patch-and-strategic-in-resource-modifier.md) design. For instructions on how to use the feature, please refer to the [Resource Modifiers](https://velero.io/docs/v1.13/restore-resource-modifiers/) doc.
+
+#### Node-Agent Concurrency
+Velero data movement activities from fs-backups and CSI snapshot data movements run in Velero node-agent, so may be hosted by every node in the cluster and consume resources (i.e. CPU, memory, network bandwidth) from there. With v1.13, users are allowed to configure how many data movement activities (a.k.a, loads) run in each node globally or by node, so that users can better leverage the performance of Velero data movement activities and the resource consumption in the cluster. For more information, check the [Node-Agent Concurrency](https://velero.io/docs/v1.13/node-agent-concurrency/) document. 
+
+#### Parallel Files Upload Options
+Velero now supports configurable options for parallel files upload when using Kopia uploader to do fs-backups or CSI snapshot data movements which makes speed up backup possible.
+For more information, please check [Here](https://velero.io/docs/v1.13/backup-reference/#parallel-files-upload).
+
+#### Write Sparse Files Options
+If using fs-restore or CSI snapshot data movements, it’s supported to write sparse files during restore. For more information, please check [Here](https://velero.io/docs/v1.13/restore-reference/#write-sparse-files).
+
+#### Backup Describe
+In v1.13, the Backup Volume section is added to the velero backup describe command output. The backup Volumes section describes information for all the volumes included in the backup of various backup types, i.e. native snapshot, fs-backup, CSI snapshot, and CSI snapshot data movement. Particularly, the velero backup description now supports showing the information of CSI snapshot data movements, which is not supported in v1.12.
+
+Additionally, backup describe command will not check EnableCSI feature gate from client side, so if a backup has volumes with CSI snapshot or CSI snapshot data movement, backup describe command always shows the corresponding information in its output.
+
+#### Backup's new VolumeInfo metadata
+Create a new metadata file in the backup repository's backup name sub-directory to store the backup-including PVC and PV information. The information includes the backing-up method of the PVC and PV data, snapshot information, and status. The VolumeInfo metadata file determines how the PV resource should be restored. The Velero downstream software can also use this metadata file to get a summary of the backup's volume data information.
+
+#### Enhancement for CSI Snapshot Data Movements when Velero Pod Restart
+When performing backup and restore operations, enhancements have been implemented for Velero server pods or node agents to ensure that the current backup or restore process is not stuck or interrupted after restart due to certain exceptional circumstances.
+
+#### New status fields added to show hook execution details
+Hook execution status is now included in the backup/restore CR status and displayed in the backup/restore describe command output. Specifically, it will show the number of hooks which attempted to execute under the HooksAttempted  field and the number of hooks which failed to execute under the HooksFailed  field. 
+
+#### AWS SDK Bump Up
+Bump up AWS SDK for Go to version 2, which offers significant performance improvements in CPU and memory utilization over version 1.
+
+#### Azure AD/Workload Identity Support
+Azure AD/Workload Identity is the recommended approach to do the authentication with Azure services/AKS, Velero has introduced support for Azure AD/Workload Identity on the Velero Azure plugin side in previous releases, and in v1.13.0 Velero adds new support for Kopia operations(file system backup/data mover/etc.) with Azure AD/Workload Identity.
+
+#### Runtime and dependencies
+To fix CVEs and keep pace with Golang, Velero made changes as follows:
+* Bump Golang runtime to v1.21.6.
+* Bump several dependent libraries to new versions.
+* Bump Kopia to v0.15.0.
+
+
+### Breaking changes
+* Backup describe command: due to the backup describe output enhancement, some existing information (i.e. the output for native snapshot, CSI snapshot, and fs-backup) has been moved to the Backup Volumes section with some format changes.
+* API type changes: changes the field [DataMoverConfig](https://github.com/vmware-tanzu/velero/blob/v1.13.0/pkg/apis/velero/v2alpha1/data_upload_types.go#L54) in DataUploadSpec from `*map[string][string]`` to `map[string]string`
+* Velero install command: due to the issue [#7264](https://github.com/vmware-tanzu/velero/issues/7264), v1.13.0 introduces a break change that make the informer cache enabled by default to keep the actual behavior consistent with the helper message(the informer cache is disabled by default before the change).
+
+
+### Limitations/Known issues
+* The backup's VolumeInfo metadata doesn't have the information updated in the async operations. This function could be supported in v1.14 release. 
+
+### Note
+* Velero introduces the informer cache which is enabled by default. The informer cache improves the restore performance but may cause higher memory consumption. Increase the memory limit of the Velero pod or disable the informer cache by specifying the `--disable-informer-cache` option when installing Velero if you get the OOM error.
+
+### Deprecation announcement
+* The generated k8s clients, informers, and listers are deprecated in the Velero v1.13 release. They are put in the Velero repository's pkg/generated directory. According to the n+2 supporting policy, the deprecated are kept for two more releases. The pkg/generated directory should be deleted in the v1.15 release.
+* After the backup VolumeInfo metadata file is added to the backup, Velero decides how to restore the PV resource according to the VolumeInfo content. To support the backup generated by the older version of Velero, the old logic is also kept. The support for the backup without the VolumeInfo metadata file will be kept for two releases. The support logic will be deleted in the v1.15 release.

+## v1.14
+
+### Download
+https://github.com/vmware-tanzu/velero/releases/tag/v1.14.0
+
+### Container Image
+`velero/velero:v1.14.0`
+
+### Documentation
+https://velero.io/docs/v1.14/
+
+### Upgrading
+https://velero.io/docs/v1.14/upgrade-to-1.14/
+
+### Highlights
+
+#### The maintenance work for kopia/restic backup repositories is run in jobs
+Since velero started using kopia as the approach for filesystem-level backup/restore, we've noticed an issue when velero connects to the kopia backup repositories and performs maintenance, it sometimes consumes excessive memory that can cause the velero pod to get OOM Killed.  To mitigate this issue, the maintenance work will be moved out of velero pod to a separate kubernetes job, and the user will be able to specify the resource request in "velero install".
+#### Volume Policies are extended to support more actions to handle volumes
+In an earlier release, a flexible volume policy was introduced to skip certain volumes from a backup.  In v1.14 we've made enhancement to this policy to allow the user to set how the volumes should be backed up.  The user will be able to set "fs-backup" or "snapshot" as value of “action" in the policy and velero will backup the volumes accordingly.  This enhancement allows the user to achieve a fine-grained control like "opt-in/out" without having to update the target workload.  For more details please refer to https://velero.io/docs/v1.14/resource-filtering/#supported-volumepolicy-actions
+#### Node Selection for Data Movement Backup
+In velero the data movement flow relies on datamover pods, and these pods may take substantial resources and keep running for a long time.  In v1.14, the user will be able to create a configmap to define the eligible nodes on which the datamover pods are launched.  For more details refer to https://velero.io/docs/v1.14/data-movement-backup-node-selection/ 
+#### VolumeInfo metadata for restored volumes
+In v1.13, we introduced volumeinfo metadata for backup to help velero CLI and downstream adopter understand how velero handles each volume during backup.  In v1.14, similar metadata will be persisted for each restore. velero CLI is also updated to bring more info in the output of "velero restore describe".
+#### "Finalizing" phase is introduced to restores
+The "Finalizing" phase is added to the state transition flow to restore, which helps us fix several issues: The labels added to PVs will be restored after the data in the PV is restored via volumesnapshotter.  The post restore hook will be executed after datamovement is finished.
+#### Certificate-based authentication support for Azure
+Besides the service principal with secret(password)-based authentication, Velero introduces the new support for service principal with certificate-based authentication in v1.14.0. This approach enables you to adopt a phishing resistant authentication by using conditional access policies, which better protects Azure resources and is the recommended way by Azure.
+
+### Runtime and dependencies
+* Golang runtime: v1.22.2
+* kopia: v0.17.0
+
+### Limitations/Known issues
+* For the external BackupItemAction plugins that take snapshots for PVs, such as vsphere plugin.  If the plugin checks the value of the field "snapshotVolumes" in the backup spec as a criteria for snapshot, the settings in the volume policy will not take effect.  For example, if the "snapshotVolumes" is set to False in the backup spec, but a volume meets the condition in the volume policy for "snapshot" action, because the plugin will not check the settings in the volume policy, the plugin will not take snapshot for the volume.  For more details please refer to #7818
+
+### Breaking changes
+* CSI plugin has been merged into velero repo in v1.14 release.  It will be installed by default as an internal plugin, and should not be installed via "–plugins " parameter in "velero install" command.
+* The default resource requests and limitations for node agent are removed in v1.14, to make the node agent pods have the QoS class of "BestEffort", more details please refer to #7391
+* There's a change in namespace filtering behavior during backup:  In v1.14, when the includedNamespaces/excludedNamespaces fields are not set and the labelSelector/OrLabelSelectors are set in the backup spec, the backup will only include the namespaces which contain the resources that match the label selectors, while in previous releases all namespaces will be included in the backup with such settings.  More details refer to #7105
+* Patching the PV in the "Finalizing" state may cause the restore to be in "PartiallyFailed" state when the PV is blocked in "Pending" state, while in the previous release the restore may end up being in "Complete" state. For more details refer to #7866

+
+### Upgrading
+https://velero.io/docs/v1.15/upgrade-to-1.15/
+
+### Highlights
+#### Data mover micro service
+Data transfer activities for CSI Snapshot Data Movement are moved from node-agent pods to dedicate backupPods or restorePods. This brings many benefits such as:  
+- This avoids to access volume data through host path, while host path access is privileged and may involve security escalations, which are concerned by users.
+- This enables users to to control resource (i.e., cpu, memory) allocations in a granular manner, e.g., control them per backup/restore of a volume.
+- This enhances the resilience, crash of one data movement activity won't affect others.
+- This prevents unnecessary full backup because of host path changes after workload pods restart.
+- For more information, check the design https://github.com/vmware-tanzu/velero/blob/main/design/Implemented/vgdp-micro-service/vgdp-micro-service.md.
+
+#### Item Block concepts and ItemBlockAction (IBA) plugin
+Item Block concepts are introduced for resource backups to help to achieve multiple thread backups. Specifically, correlated resources are categorized in the same item block and item blocks could be processed concurrently in multiple threads.  
+ItemBlockAction plugin is introduced to help Velero to categorize resources into item blocks. At present, Velero provides built-in IBAs for pods and PVCs and Velero also supports customized IBAs for any resources.  
+In v1.15, Velero doesn't support multiple thread process of item blocks though item block concepts and IBA plugins are fully supported. The multiple thread support will be delivered in future releases.  
+For more information, check the design https://github.com/vmware-tanzu/velero/blob/main/design/backup-performance-improvements.md.  
+
+#### Node selection for repository maintenance job
+Repository maintenance are resource consuming tasks, Velero now allows you to configure the nodes to run repository maintenance jobs, so that you can run repository maintenance jobs in idle nodes or avoid them to run in nodes hosting critical workloads.  
+To support the configuration, a new repository maintenance configuration configMap is introduced.  
+For more information, check the document https://velero.io/docs/v1.15/repository-maintenance/.  
+
+#### Backup PVC read-only configuration
+In 1.15, Velero allows you to configure the data mover backupPods to read-only mount the backupPVCs. In this way, the data mover expose process could be significantly accelerated for some storages (i.e., ceph).  
+To support the configuration, a new backup PVC configuration configMap is introduced.  
+For more information, check the document https://velero.io/docs/v1.15/data-movement-backup-pvc-configuration/.  
+
+#### Backup PVC storage class configuration
+In 1.15, Velero allows you to configure the storageclass used by the data mover backupPods. In this way, the provision of backupPVCs don't need to adhere to the same pattern as workload PVCs, e.g., for a backupPVC, it only needs one replica, whereas, the a workload PVC may have multiple replicas.  
+To support the configuration, the same backup PVC configuration configMap is used.  
+For more information, check the document https://velero.io/docs/v1.15/data-movement-backup-pvc-configuration/.  
+
+#### Backup repository data cache configuration
+The backup repository may need to cache data on the client side during various repository operations, i.e., read, write, maintenance, etc. The cache consumes the root file system space of the pod where the repository access happens.  
+In 1.15, Velero allows you to configure the total size of the cache per repository. In this way, if your pod doesn't have enough space in its root file system, the pod won't be evicted due to running out of ephemeral storage.  
+To support the configuration, a new backup repository configuration configMap is introduced.  
+For more information, check the document https://velero.io/docs/v1.15/backup-repository-configuration/.  
+
+#### Performance improvements
+In 1.15, several performance related issues/enhancements are included, which makes significant performance improvements in specific scenarios:  
+- There was a memory leak of Velero server after plugin calls, now it is fixed, see issue https://github.com/vmware-tanzu/velero/issues/7925
+- The `client-burst/client-qps` parameters are automatically inherited to plugins, so that you can use the same velero server parameters to accelerate the plugin executions when large number of API server calls happen, see issue https://github.com/vmware-tanzu/velero/issues/7806
+- Maintenance of Kopia repository takes huge memory in scenarios that huge number of files have been backed up, Velero 1.15 has included the Kopia upstream enhancement to fix the problem, see issue https://github.com/vmware-tanzu/velero/issues/7510

+Due to an issue of Kubernetes upstream, if a volume is mounted as read-only in SELinux environments, the read privilege is not granted to any user, as a result, the data mover backup will fail. On the other hand, the backupPVC must be mounted as read-only in order to accelerate the data mover expose process.  
+Therefore, a user option is added in the same backup PVC configuration configMap, once the option is enabled, the backupPod container will run as a super privileged container and disable SELinux access control. If you have concern in this super privileged container or you have configured [pod security admissions](https://kubernetes.io/docs/concepts/security/pod-security-admission/) and don't allow super privileged containers, you will not be able to use this read-only backupPVC feature and lose the benefit to accelerate the data mover expose process.  
+
+### Breaking changes
+#### Deprecation of Restic
+Restic path for fs-backup is in deprecation process starting from 1.15. According to [Velero deprecation policy](https://github.com/vmware-tanzu/velero/blob/v1.15/GOVERNANCE.md#deprecation-policy), for 1.15, if Restic path is used the backup/restore of fs-backup still creates and succeeds, but you will see warnings in below scenarios:  
+- When `--uploader-type=restic` is used in Velero installation
+- When Restic path is used to create backup/restore of fs-backup
+
+#### node-agent configuration name is configurable
+Previously, a fixed name is searched for node-agent configuration configMap. Now in 1.15, Velero allows you to customize the name of the configMap, on the other hand, the name must be specified by node-agent server parameter `node-agent-configmap`.  
+
+#### Repository maintenance job configurations in Velero server parameter are moved to repository maintenance job configuration configMap
+In 1.15, below Velero server parameters for repository maintenance jobs are moved to the repository maintenance job configuration configMap. While for back compatibility reason, the same Velero sever parameters are preserved as is. But the configMap is recommended and the same values in the configMap take preference if they exist in both places:  
+```
+--keep-latest-maintenance-jobs
+--maintenance-job-cpu-request
+--maintenance-job-mem-request
+--maintenance-job-cpu-limit
+--maintenance-job-mem-limit
+```
+
+#### Changing PVC selected-node feature is deprecated
+In 1.15, the [Changing PVC selected-node feature](https://velero.io/docs/v1.15/restore-reference/#changing-pvc-selected-node) enters deprecation process and will be removed in future releases according to [Velero deprecation policy](https://github.com/vmware-tanzu/velero/blob/v1.15/GOVERNANCE.md#deprecation-policy). Usage of this feature for any purpose is not recommended.

+
+### Download

+
+### Container Image
+`velero/velero:v1.16.0`
+
+### Documentation
+https://velero.io/docs/v1.16/
+
+### Upgrading
+https://velero.io/docs/v1.16/upgrade-to-1.16/
+
+### Highlights
+#### Windows cluster support
+In v1.16, Velero supports to run in Windows clusters and backup/restore Windows workloads, either stateful or stateless:
+ * Hybrid build and all-in-one image: the build process is enhanced to build an all-in-one image for hybrid CPU architecture and hybrid platform. For more information, check the design https://github.com/vmware-tanzu/velero/blob/main/design/multiple-arch-build-with-windows.md
+ * Deployment in Windows clusters: Velero node-agent, data mover pods and maintenance jobs now support to run in both linux and Windows nodes
+ * Data mover backup/restore Windows workloads: Velero built-in data mover supports Windows workloads throughout its full cycle, i.e., discovery, backup, restore, pre/post hook, etc. It automatically identifies Windows workloads and schedules data mover pods to the right group of nodes
+
+Check the epic issue https://github.com/vmware-tanzu/velero/issues/8289 for more information.  
+
+#### Parallel Item Block backup
+v1.16 now supports to back up item blocks in parallel. Specifically, during backup, correlated resources are grouped in item blocks and Velero backup engine creates a thread pool to back up the item blocks in parallel. This significantly improves the backup throughput, especially when there are large scale of resources.  
+Pre/post hooks also belongs to item blocks, so will also run in parallel along with the item blocks.  
+Users are allowed to configure the parallelism through the `--item-block-worker-count` Velero server parameter. If not configured, the default parallelism is 1.  
+
+For more information, check issue https://github.com/vmware-tanzu/velero/issues/8334.  
+
+#### Data mover restore enhancement in scalability
+In previous releases, for each volume of WaitForFirstConsumer mode, data mover restore is only allowed to happen in the node that the volume is attached. This severely degrades the parallelism and the balance of node resource(CPU, memory, network bandwidth) consumption for data mover restore (https://github.com/vmware-tanzu/velero/issues/8044).  
+
+In v1.16, users are allowed to configure data mover restores running and spreading evenly across all nodes in the cluster. The configuration is done through a new flag `ignoreDelayBinding` in node-agent configuration (https://github.com/vmware-tanzu/velero/issues/8242).  
+
+#### Data mover enhancements in observability 
+In 1.16, some observability enhancements are added:
+ * Output various statuses of intermediate objects for failures of data mover backup/restore (https://github.com/vmware-tanzu/velero/issues/8267)
+ * Output the errors when Velero fails to delete intermediate objects during clean up (https://github.com/vmware-tanzu/velero/issues/8125)
+
+The outputs are in the same node-agent log and enabled automatically.  
+
+#### CSI snapshot backup/restore enhancement in usability
+In previous releases, a unnecessary VolumeSnapshotContent object is retained for each backup and synced to other clusters sharing the same backup storage location. And during restore, the retained VolumeSnapshotContent is also restored unnecessarily.  
+
+In 1.16, the retained VolumeSnapshotContent is removed from the backup, so no unnecessary CSI objects are synced or restored.  
+
+For more information, check issue https://github.com/vmware-tanzu/velero/issues/8725.  
+
+#### Backup Repository Maintenance enhancement in resiliency and observability
+In v1.16, some enhancements of backup repository maintenance are added to improve the observability and resiliency:
+ * A new backup repository maintenance history section, called `RecentMaintenance`, is added to the BackupRepository CR. Specifically, for each BackupRepository, including start/completion time, completion status and error message. (https://github.com/vmware-tanzu/velero/issues/7810)
+ * Running maintenance jobs are now recaptured after Velero server restarts. (https://github.com/vmware-tanzu/velero/issues/7753)
+ * The maintenance job will not be launched for readOnly BackupStorageLocation. (https://github.com/vmware-tanzu/velero/issues/8238)
+ * The backup repository will not try to initialize a new repository for readOnly BackupStorageLocation. (https://github.com/vmware-tanzu/velero/issues/8091)
+ * Users now are allowed to configure the intervals of an effective maintenance in the way of `normalGC`, `fastGC` and `eagerGC`, through the `fullMaintenanceInterval` parameter in backupRepository configuration. (https://github.com/vmware-tanzu/velero/issues/8364)
+
+#### Volume Policy enhancement of filtering volumes by PVC labels
+In v1.16, Volume Policy is extended to support filtering volumes by PVC labels. (https://github.com/vmware-tanzu/velero/issues/8256).   
+
+#### Resource Status restore per object
+In v1.16, users are allowed to define whether to restore resource status per object through an annotation `velero.io/restore-status` set on the object. (https://github.com/vmware-tanzu/velero/issues/8204).  
+
+#### Velero Restore Helper binary is merged into Velero image 
+In v1.16, Velero banaries, i.e., velero, velero-helper and velero-restore-helper, are all included into the single Velero image. (https://github.com/vmware-tanzu/velero/issues/8484).  
+
+### Runtime and dependencies
+Golang runtime: 1.23.7  
+kopia: 0.19.0
+
+### Limitations/Known issues
+#### Limitations of Windows support
+  * fs-backup is not supported for Windows workloads and so fs-backup runs only in linux nodes for linux workloads

+## v1.17
+
+### Download
+https://github.com/vmware-tanzu/velero/releases/tag/v1.17.0
+
+### Container Image
+`velero/velero:v1.17.0`
+
+### Documentation
+https://velero.io/docs/v1.17/
+
+### Upgrading
+https://velero.io/docs/v1.17/upgrade-to-1.17/
+
+### Highlights
+#### Modernized fs-backup
+In v1.17, Velero fs-backup is modernized to the micro-service architecture, which brings below benefits:  
+- Many features that were absent to fs-backup are now available, i.e., load concurrency control, cancel, resume on restart, etc.
+- fs-backup is more robust, the running backup/restore could survive from node-agent restart; and the resource allocation is in a more granular manner, the failure of one backup/restore won't impact others.  
+- The resource usage of node-agent is steady, especially, the node-agent pods won't request huge memory and hold it for a long time.  
+
+Check design https://github.com/vmware-tanzu/velero/blob/main/design/vgdp-micro-service-for-fs-backup/vgdp-micro-service-for-fs-backup.md for more details.  
+
+#### fs-backup support Windows cluster
+In v1.17, Velero fs-backup supports to backup/restore Windows workloads. By leveraging the new micro-service architecture for fs-backup, data mover pods could run in Windows nodes and backup/restore Windows volumes. Together with CSI snapshot data movement for Windows which is delivered in 1.16, Velero now supports Windows workload backup/restore in full scenarios.  
+Check design https://github.com/vmware-tanzu/velero/blob/main/design/vgdp-micro-service-for-fs-backup/vgdp-micro-service-for-fs-backup.md for more details.  
+
+#### Volume group snapshot support
+In v1.17, Velero supports [volume group snapshots](https://kubernetes.io/blog/2024/12/18/kubernetes-1-32-volume-group-snapshot-beta/) which is a beta feature in Kubernetes upstream, for both CSI snapshot backup and CSI snapshot data movement. This allows a snapshot to be taken from multiple volumes at the same point-in-time to achieve write order consistency, which is helpful to achieve better data consistency when multiple volumes being backed up are correlated.  
+Check the document https://velero.io/docs/main/volume-group-snapshots/ for more details.  
+
+#### Priority class support
+In v1.17, [Kubernetes priority class](https://kubernetes.io/docs/concepts/scheduling-eviction/pod-priority-preemption/#priorityclass) is supported for all modules across Velero. Specifically, users are allowed to configure priority class to Velero server, node-agent, data mover pods, backup repository maintenance jobs separately.  
+Check design https://github.com/vmware-tanzu/velero/blob/main/design/Implemented/priority-class-name-support_design.md for more details.  
+
+#### Scalability and Resiliency improvements of data movers
+##### Reduce excessive number of data mover pods in Pending state
+In v1.17, Velero allows users to set a `PrepareQueueLength` in the node-agent configuration, data mover pods and volumes out of this number won't be created until data path quota is available, so that excessive number cluster resources won't  be taken unnecessarily, which is particularly helpful for large scale environments. This improvement applies to all kinds of data movements, including fs-backup and CSI snapshot data movement.  
+Check design https://github.com/vmware-tanzu/velero/blob/main/design/node-agent-load-soothing.md for more details.  
+
+##### Enhancement on node-agent restart handling for data movements
+In v1.17, data movements in all phases could survive from node-agent restart and resume themselves; when a data movement gets orphaned in special cases, e.g., cluster node absent, it could also be canceled appropriately after the restart. This improvement applies to all kinds of data movements, including fs-backup and CSI snapshot data movement.  
+Check issue https://github.com/vmware-tanzu/velero/issues/8534 for more details.  
+
+##### CSI snapshot data movement restore node-selection and node-selection by storage class
+In v1.17, CSI snapshot data movement restore acquires the same node-selection capability as backup, that is, users could specify which nodes can/cannot run data mover pods for both backup and restore now. And users are also allowed to configure the node-selection per storage class, which is particularly helpful to the environments where a storage class are not usable by all cluster nodes.  
+Check issue https://github.com/vmware-tanzu/velero/issues/8186 and https://github.com/vmware-tanzu/velero/issues/8223 for more details.  
+
+#### Include/exclude policy support for resource policy
+In v1.17, Velero resource policy supports `includeExcludePolicy` besides the existing `volumePolicy`. This allows users to set include/exclude filters for resources in a resource policy configmap, so that these filters are reusable among multiple backups.  
+Check the document https://velero.io/docs/main/resource-filtering/#creating-resource-policies:~:text=resources%3D%22*%22-,Resource%20policies,-Velero%20provides%20resource for more details.

+
+### Limitations/Known issues
+
+### Breaking changes
+#### Deprecation of Restic
+According to [Velero deprecation policy](https://github.com/vmware-tanzu/velero/blob/main/GOVERNANCE.md#deprecation-policy), backup of fs-backup under Restic path is removed in v1.17, so `--uploader-type=restic` is not a valid installation configuration anymore. This means you cannot create a backup under Restic path, but you can still restore from the previous backups under Restic path until v1.19.  
+
+#### Repository maintenance job configurations are removed from Velero server parameter
+Since the repository maintenance job configurations are moved to repository maintenance job configMap, in v1.17 below Velero sever parameters are removed:
+- --keep-latest-maintenance-jobs
+- --maintenance-job-cpu-request
+- --maintenance-job-mem-request
+- --maintenance-job-cpu-limit
+- --maintenance-job-mem-limit

+## v1.18
+
+### Download
+https://github.com/vmware-tanzu/velero/releases/tag/v1.18.0
+
+### Container Image
+`velero/velero:v1.18.0`
+
+### Documentation
+https://velero.io/docs/v1.18/
+
+### Upgrading
+https://velero.io/docs/v1.18/upgrade-to-1.18/
+
+### Highlights
+#### Concurrent backup
+In v1.18, Velero is capable to process multiple backups concurrently. This is a significant usability improvement, especially for multiple tenants or multiple users case, backups submitted from different users could run their backups simultaneously without interfering with each other.  
+
+Check design https://github.com/vmware-tanzu/velero/blob/main/design/Implemented/concurrent-backup-processing.md for more details.
+
+#### Cache volume for data movers
+In v1.18, Velero allows users to configure cache volumes for data mover pods during restore for CSI snapshot data movement and fs-backup. This brings below benefits:
+- Solve the problem that data mover pods fail to when pod's ephemeral disk is limited
+- Solve the problem that multiple data mover pods fail to run concurrently in one node when the node's ephemeral disk is limited
+- Working together with backup repository's cache limit configuration, cache volume with appropriate size helps to improve the restore throughput
+
+Check design https://github.com/vmware-tanzu/velero/blob/main/design/Implemented/backup-repo-cache-volume.md for more details.
+
+#### Incremental size for data movers
+In v1.18, Velero allows users to observe the incremental size of data movers backups for CSI snapshot data movement and fs-backup, so that users could visually see the data reduction due to incremental backup.
+
+#### Wildcard support for namespaces
+In v1.18, Velero allows to use Glob regular expressions for namespace filters during backup and restore, so that users could filter namespaces in a batch manner.
+
+#### VolumePolicy for PVC phase
+In v1.18, Velero VolumePolicy supports actions by PVC phase, which help users to do special operations for PVCs with a specific phase, e.g., skip PVCs in Pending/Lost status from the backup.  
+
+#### Scalability and Resiliency improvements
+##### Prevent Velero server OOM Kill for large backup repositories
+In v1.18, some backup repository operations are delay executed out of Velero server, so Velero server won't be OOM Killed.
+
+#### Performance improvement for VolumePolicy
+In v1.18, VolumePolicy is enhanced for large number of pods/PVCs so that the performance is significantly improved.
+
+#### Events for data mover pod diagnostic
+In v1.18, events are recorded into data mover pod diagnostic, which allows user to see more information for troubleshooting when the data mover pod fails.
+
+### Runtime and dependencies
+Golang runtime: 1.25.7  
+kopia: 0.22.3
+
+### Limitations/Known issues
+
+### Breaking changes
+#### Deprecation of PVC selected node feature
+According to [Velero deprecation policy](https://github.com/vmware-tanzu/velero/blob/main/GOVERNANCE.md#deprecation-policy), PVC selected node feature is deprecated in v1.18. Velero could appropriately handle PVC's selected-node annotation, so users don't need to do anything particularly.

+# Extend VolumePolicies to support more actions
+
+## Abstract
+
+Currently, the [VolumePolicies feature](https://github.com/vmware-tanzu/velero/blob/main/design/Implemented/handle-backup-of-volumes-by-resources-filters.md) which can be used to filter/handle volumes during backup only supports the skip action on matching conditions. Users need more actions to be supported.
+
+## Background
+
+The `VolumePolicies` feature was introduced in Velero 1.11 as a flexible way to handle volumes. The main agenda of
+introducing the VolumePolicies feature was to improve the overall user experience when performing backup operations
+for volume resources, the feature enables users to group volumes according the `conditions` (criteria) specified and
+also lets you specify the `action` that velero needs to take for these grouped volumes during the backup operation.
+The limitation being that currently `VolumePolicies` only supports `skip` as an action, We want to extend the `action`
+functionality to support more usable options like `fs-backup` (File system backup) and `snapshot` (VolumeSnapshots).
+
+## Goals
+- Extending the VolumePolicies to support more actions like `fs-backup` (File system backup) and `snapshot` (VolumeSnapshots).
+- Improve user experience when backing up Volumes via Velero
+
+## Non-Goals
+- No changes to existing approaches to opt-in/opt-out annotations for volumes
+- No changes to existing `VolumePolicies` functionalities
+- No additions or implementations to support more granular actions like `snapshot-csi` and `snapshot-datamover`. These actions can be implemented as a future enhancement
+
+
+## Use-cases/Scenarios
+
+**Use-case 1:**
+- A user wants to use `snapshot` (volumesnapshots) backup option for all the csi supported volumes and `fs-backup` for the rest of the volumes.
+- Currently, velero supports this use-case but the user experience is not that great.
+- The user will have to individually annotate the volume mounting pod with the annotation "backup.velero.io/backup-volumes" for `fs-backup`
+- This becomes cumbersome at scale.
+- Using `VolumePolicies`, the user can just specify 2 simple `VolumePolicies` like for csi supported volumes as `snapshot` action and rest can be backed up`fs-backup` action:
+```yaml
+version: v1
+volumePolicies:
+  - conditions:
+      storageClass:
+        - gp2
+    action:
+      type: snapshot
+  - conditions: {}
+    action:
+      type: fs-backup
+```
+
+**Use-case 2:**
+- A user wants to use `fs-backup` for nfs volumes pertaining to a particular server
+- In such a scenario the user can just specify a `VolumePolicy` like:
+```yaml
+version: v1
+volumePolicies:
+- conditions:
+    nfs:
+      server: 192.168.200.90
+  action:
+    type: fs-backup
+```
+## High-Level Design
+- When the VolumePolicy action is set as `fs-backup` the backup workflow modifications would be:
+  - We call [backupItem() -> backupItemInternal()](https://github.com/vmware-tanzu/velero/blob/main/pkg/backup/item_backupper.go#L95) on all the items that are to be backed up
+  - Here when we encounter [Pod as an item ](https://github.com/vmware-tanzu/velero/blob/main/pkg/backup/item_backupper.go#L195)
+  - We will have to modify the backup workflow to account for the `fs-backup` VolumePolicy action
+
+
+- When the VolumePolicy action is set as `snapshot` the backup workflow modifications would be:
+  - Once again, We call [backupItem() -> backupItemInternal()](https://github.com/vmware-tanzu/velero/blob/main/pkg/backup/item_backupper.go#L95) on all the items that are to be backed up
+  - Here when we encounter [Persistent Volume as an item](https://github.com/vmware-tanzu/velero/blob/d4128542590470b204a642ee43311921c11db880/pkg/backup/item_backupper.go#L253)
+  - And we call the [takePVSnapshot func](https://github.com/vmware-tanzu/velero/blob/d4128542590470b204a642ee43311921c11db880/pkg/backup/item_backupper.go#L508)
+  - We need to modify the takePVSnapshot function to account for the `snapshot` VolumePolicy action.
+  - In case of csi snapshots for PVC objects, these snapshot actions are taken by the velero-plugin-for-csi, we need to modify the [executeActions()](https://github.com/vmware-tanzu/velero/blob/512fe0dabdcb3bbf1ca68a9089056ae549663bcf/pkg/backup/item_backupper.go#L232) function to account for the `snapshot` VolumePolicy action.
+
+**Note:** `Snapshot` action can either be a native snapshot or a csi snapshot, as is the case with the current flow where velero itself makes the decision based on the backup CR.
+
+## Detailed Design
+- Update VolumePolicy action type validation to account for `fs-backup` and `snapshot` as valid VolumePolicy actions.
+- Modifications needed for `fs-backup` action:
+  - Now based on the specification of volume policy on backup request we will decide whether to go via legacy pod annotations approach or the newer volume policy based fs-backup action approach.
+  - If there is a presence of volume policy(fs-backup/snapshot) on the backup request that matches as an action for a volume we use the newer volume policy approach to get the list of the volumes for `fs-backup` action
+  - Else continue with the annotation based legacy approach workflow.
+
+- Modifications needed for `snapshot` action:
+  - In the [takePVSnapshot function](https://github.com/vmware-tanzu/velero/blob/d4128542590470b204a642ee43311921c11db880/pkg/backup/item_backupper.go#L508) we will check the PV fits the volume policy criteria and see if the associated action is `snapshot`
+  - If it is not snapshot then we skip the further workflow and avoid taking the snapshot of the PV
+  - Similarly, For csi snapshot of PVC object, we need to do similar changes in [executeAction() function](https://github.com/vmware-tanzu/velero/blob/512fe0dabdcb3bbf1ca68a9089056ae549663bcf/pkg/backup/item_backupper.go#L348). we will check the PVC fits the volume policy criteria and see if the associated action is `snapshot` via csi plugin
+  - If it is not snapshot then we skip the csi BIA execute action and avoid taking the snapshot of the PVC by not invoking the csi plugin action for the PVC
+
+**Note:**
+- When we are using the `VolumePolicy` approach for backing up the volumes then the volume policy criteria and action need to be specific and explicit, there is no default behavior, if a volume matches `fs-backup` action then `fs-backup` method will be used for that volume and similarly if the volume matches the criteria for `snapshot` action then the snapshot workflow will be used for the volume backup.
+- Another thing to note is the workflow proposed in this design uses the legacy `opt-in/opt-out` approach as a fallback option. For instance, the user specifies a VolumePolicy but for a particular volume included in the backup there are no actions(fs-backup/snapshot) matching in the volume policy for that volume, in such a scenario the legacy approach will be used for backing up the particular volume.
+- The relation between the `VolumePolicy` and the backup's legacy parameter `SnapshotVolumes`: 
+  - The `VolumePolicy`'s `snapshot` action matching for volume has higher priority. When there is a `snapshot` action matching for the selected volume, it will be backed by the snapshot way, no matter of the `backup.Spec.SnapshotVolumes` setting.
+  - If there is no `snapshot` action matching the selected volume in the `VolumePolicy`, then the volume will be backed up by `snapshot` way, if the `backup.Spec.SnapshotVolumes` is not set to false.
+- The relation between the `VolumePolicy` and the backup's legacy filesystem `opt-in/opt-out` approach:
+  - The `VolumePolicy`'s `fs-backup` action matching for volume has higher priority. When there is a `fs-backup` action matching for the selected volume, it will be backed by the fs-backup way, no matter of the `backup.Spec.DefaultVolumesToFsBackup` setting and the pod's `opt-in/opt-out` annotation setting.
+  - If there is no `fs-backup` action matching the selected volume in the `VolumePolicy`, then the volume will be backed up by the legacy `opt-in/opt-out` way.
+
+## Implementation
+
+- The implementation should be included in velero 1.14
+
+- We will introduce a `VolumeHelper` interface. It will consist of two methods:
+```go
+type VolumeHelper interface {
+	ShouldPerformSnapshot(obj runtime.Unstructured, groupResource schema.GroupResource) (bool, error)
+	ShouldPerformFSBackup(volume corev1api.Volume, pod corev1api.Pod) (bool, error)
+}
+```
+-  The `VolumeHelperImpl` struct will implement the `VolumeHelper` interface and will consist of the functions that we will use through the backup workflow to accommodate volume policies for PVs and PVCs.
+```go
+type volumeHelperImpl struct {
+	volumePolicy             *resourcepolicies.Policies
+	snapshotVolumes          *bool
+	logger                   logrus.FieldLogger
+	client                   crclient.Client
+	defaultVolumesToFSBackup bool
+	backupExcludePVC         bool
+}
+
+```
+
+- We will create an instance of the structure `volumeHelperImpl` in `item_backupper.go`
+```go
+	itemBackupper := &itemBackupper{
+		...
+		volumeHelperImpl: volumehelper.NewVolumeHelperImpl(
+			resourcePolicy,
+			backupRequest.Spec.SnapshotVolumes,
+			log,
+			kb.kbClient,
+			boolptr.IsSetToTrue(backupRequest.Spec.DefaultVolumesToFsBackup),
+			!backupRequest.ResourceIncludesExcludes.ShouldInclude(kuberesource.PersistentVolumeClaims.String()),
+		),
+	}
+```
+
+
+#### FS-Backup
+- Regarding `fs-backup` action to decide whether to use legacy annotation based approach or volume policy based approach:
+  - We will use the `vh.ShouldPerformFSBackup()` function from the `volumehelper` package
+  - Functions involved in processing `fs-backup` volume policy action will somewhat look like:
+
+```go
+func (v volumeHelperImpl) ShouldPerformFSBackup(volume corev1api.Volume, pod corev1api.Pod) (bool, error) {
+	if !v.shouldIncludeVolumeInBackup(volume) {
+		v.logger.Debugf("skip fs-backup action for pod %s's volume %s, due to not pass volume check.", pod.Namespace+"/"+pod.Name, volume.Name)
+		return false, nil
+	}
+
+	if v.volumePolicy != nil {
+		pvc, err := kubeutil.GetPVCForPodVolume(&volume, &pod, v.client)
+		if err != nil {
+			v.logger.WithError(err).Errorf("fail to get PVC for pod %s", pod.Namespace+"/"+pod.Name)
+			return false, err
+		}
+		pv, err := kubeutil.GetPVForPVC(pvc, v.client)
+		if err != nil {
+			v.logger.WithError(err).Errorf("fail to get PV for PVC %s", pvc.Namespace+"/"+pvc.Name)
+			return false, err
+		}
+
+		action, err := v.volumePolicy.GetMatchAction(pv)
+		if err != nil {
+			v.logger.WithError(err).Errorf("fail to get VolumePolicy match action for PV %s", pv.Name)
+			return false, err
+		}
+
+		if action != nil {
+			if action.Type == resourcepolicies.FSBackup {
+				v.logger.Infof("Perform fs-backup action for volume %s of pod %s due to volume policy match",
+					volume.Name, pod.Namespace+"/"+pod.Name)
+				return true, nil
+			} else {
+				v.logger.Infof("Skip fs-backup action for volume %s for pod %s because the action type is %s",
+					volume.Name, pod.Namespace+"/"+pod.Name, action.Type)
+				return false, nil
+			}
+		}
+	}
+
+	if v.shouldPerformFSBackupLegacy(volume, pod) {
+		v.logger.Infof("Perform fs-backup action for volume %s of pod %s due to opt-in/out way",
+			volume.Name, pod.Namespace+"/"+pod.Name)
+		return true, nil
+	} else {
+		v.logger.Infof("Skip fs-backup action for volume %s of pod %s due to opt-in/out way",
+			volume.Name, pod.Namespace+"/"+pod.Name)
+		return false, nil
+	}
+}
+```
+
+- The main function from the above will be called when we encounter Pods during the backup workflow:
+```go
+			for _, volume := range pod.Spec.Volumes {
+				shouldDoFSBackup, err := ib.volumeHelperImpl.ShouldPerformFSBackup(volume, *pod)
+				if err != nil {
+					backupErrs = append(backupErrs, errors.WithStack(err))
+				}
+				...
+			}
+```
+
+#### Snapshot (PV)
+
+- Making sure that `snapshot` action is skipped for PVs that do not fit the volume policy criteria, for this we will use the `vh.ShouldPerformSnapshot` from the `VolumeHelperImpl(vh)` receiver.
+```go
+func (v *volumeHelperImpl) ShouldPerformSnapshot(obj runtime.Unstructured, groupResource schema.GroupResource) (bool, error) {
+	// check if volume policy exists and also check if the object(pv/pvc) fits a volume policy criteria and see if the associated action is snapshot
+	// if it is not snapshot then skip the code path for snapshotting the PV/PVC
+	pvc := new(corev1api.PersistentVolumeClaim)
+	pv := new(corev1api.PersistentVolume)
+	var err error
+
+	if groupResource == kuberesource.PersistentVolumeClaims {
+		if err = runtime.DefaultUnstructuredConverter.FromUnstructured(obj.UnstructuredContent(), &pvc); err != nil {
+			return false, err
+		}
+
+		pv, err = kubeutil.GetPVForPVC(pvc, v.client)
+		if err != nil {
+			return false, err
+		}
+	}
+
+	if groupResource == kuberesource.PersistentVolumes {
+		if err = runtime.DefaultUnstructuredConverter.FromUnstructured(obj.UnstructuredContent(), &pv); err != nil {
+			return false, err
+		}
+	}
+
+	if v.volumePolicy != nil {
+		action, err := v.volumePolicy.GetMatchAction(pv)
+		if err != nil {
+			return false, err
+		}
+
+		// If there is a match action, and the action type is snapshot, return true,
+		// or the action type is not snapshot, then return false.
+		// If there is no match action, go on to the next check.
+		if action != nil {
+			if action.Type == resourcepolicies.Snapshot {
+				v.logger.Infof(fmt.Sprintf("performing snapshot action for pv %s", pv.Name))
+				return true, nil
+			} else {
+				v.logger.Infof("Skip snapshot action for pv %s as the action type is %s", pv.Name, action.Type)
+				return false, nil
+			}
+		}
+	}
+
+		// If this PV is claimed, see if we've already taken a (pod volume backup)
+	// snapshot of the contents of this PV. If so, don't take a snapshot.
+	if pv.Spec.ClaimRef != nil {
+		pods, err := podvolumeutil.GetPodsUsingPVC(
+			pv.Spec.ClaimRef.Namespace,
+			pv.Spec.ClaimRef.Name,
+			v.client,
+		)
+		if err != nil {
+			v.logger.WithError(err).Errorf("fail to get pod for PV %s", pv.Name)
+			return false, err
+		}
+
+		for _, pod := range pods {
+			for _, vol := range pod.Spec.Volumes {
+				if vol.PersistentVolumeClaim != nil &&
+					vol.PersistentVolumeClaim.ClaimName == pv.Spec.ClaimRef.Name &&
+					v.shouldPerformFSBackupLegacy(vol, pod) {
+					v.logger.Infof("Skipping snapshot of pv %s because it is backed up with PodVolumeBackup.", pv.Name)
+					return false, nil
+				}
+			}
+		}
+	}
+
+	if !boolptr.IsSetToFalse(v.snapshotVolumes) {
+		// If the backup.Spec.SnapshotVolumes is not set, or set to true, then should take the snapshot.
+		v.logger.Infof("performing snapshot action for pv %s as the snapshotVolumes is not set to false", pv.Name)
+		return true, nil
+	}
+
+	v.logger.Infof(fmt.Sprintf("skipping snapshot action for pv %s possibly due to no volume policy setting or snapshotVolumes is false", pv.Name))
+	return false, nil
+}
+```
+
+- The function `ShouldPerformSnapshot` will be used as follows in `takePVSnapshot` function of the backup workflow:
+```go
+	snapshotVolume, err := ib.volumeHelperImpl.ShouldPerformSnapshot(obj, kuberesource.PersistentVolumes)
+	if err != nil {
+		return err
+	}
+
+	if !snapshotVolume {
+		log.Info(fmt.Sprintf("skipping volume snapshot for PV %s as it does not fit the volume policy criteria specified by the user for snapshot action", pv.Name))
+		ib.trackSkippedPV(obj, kuberesource.PersistentVolumes, volumeSnapshotApproach, "does not satisfy the criteria for volume policy based snapshot action", log)
+		return nil
+	}
+```
+
+#### Snapshot (PVC)
+
+- Making sure that `snapshot` action is skipped for PVCs that do not fit the volume policy criteria, for this we will again use the `vh.ShouldPerformSnapshot` from the `VolumeHelperImpl(vh)` receiver.
+- We will pass the `VolumeHelperImpl(vh)` instance in `executeActions` method so that it is available to use.
+```go
+
+```
+- The above function will be used as follows in the `executeActions` function of backup workflow.
+- Considering the vSphere plugin doesn't support the VolumePolicy yet, don't use the VolumePolicy for vSphere plugin by now.
+```go
+		if groupResource == kuberesource.PersistentVolumeClaims {
+			if actionName == csiBIAPluginName {
+				snapshotVolume, err := ib.volumeHelperImpl.ShouldPerformSnapshot(obj, kuberesource.PersistentVolumeClaims)
+				if err != nil {
+					return nil, itemFiles, errors.WithStack(err)
+				}
+
+				if !snapshotVolume {
+					log.Info(fmt.Sprintf("skipping csi volume snapshot for PVC %s as it does not fit the volume policy criteria specified by the user for snapshot action", namespace+"/"+name))
+					ib.trackSkippedPV(obj, kuberesource.PersistentVolumeClaims, volumeSnapshotApproach, "does not satisfy the criteria for volume policy based snapshot action", log)
+					continue
+				}
+			}
+		}
+```
+
+
+## Future Implementation
+It makes sense to add more specific actions in the future, once we deprecate the legacy opt-in/opt-out approach to keep things simple. Another point of note is, csi related action can be
+easier to implement once we decide to merge the csi plugin into main velero code flow.
+In the future, we envision the following actions that can be implemented:
+- `snapshot-native`: only use volume snapshotter (native cloud provider snapshots), do nothing if not present/not compatible
+- `snapshot-csi`: only use csi-plugin, don't use volume snapshotter(native cloud provider snapshots), don't use datamover even if snapshotMoveData is true
+- `snapshot-datamover`: only use csi with datamover, don't use volume snapshotter (native cloud provider snapshots), use datamover even if snapshotMoveData is false
+
+**Note:** The above actions are just suggestions for future scope, we may not use/implement them as is. We could definitely merge these suggested actions as `Snapshot` actions and use volume policy parameters and criteria to segregate them instead of making the user explicitly supply the action names to such granular levels.

+# Apply flag for install command
+
+## Abstract
+Add an `--apply` flag to the install command that enables applying existing resources rather than creating them. This can be useful as part of the upgrade process for existing installations.
+
+## Background
+The current Velero install command creates resources but doesn't provide a direct way to apply updates to an existing installation.
+Users attempting to run the install command on an existing installation receive "already exists" messages.
+Upgrade steps for existing installs typically involve a three (or more) step process to apply updated CRDs (using `--dry-run` and piping to `kubectl apply`) and then updating/setting images on the Velero deployment and node-agent.
+
+## Goals
+- Provide a simple flag to enable applying resources on an existing Velero installation.
+- Use server-side apply to update existing resources rather than attempting to create them.
+- Maintain consistency with the regular install flow.
+
+## Non Goals
+- Implement special logic for specific version-to-version upgrades (i.e. resource deletion, etc).
+- Add complex upgrade validation or pre/post-upgrade hooks.
+- Provide rollback capabilities.
+
+## High-Level Design
+The `--apply` flag will be added to the Velero install command.
+When this flag is set, the installation process will use server-side apply to update existing resources instead of using create on new resources.
+This flag can be used as _part_ of the upgrade process, but will not always fully handle an upgrade.
+
+## Detailed Design
+The implementation adds a new boolean flag `--apply` to the install command.
+This flag will be passed through to the underlying install functions where the resource creation logic resides.
+
+When the flag is set to true:
+- The `createOrApplyResource` function will use server-side apply with field manager "velero-cli" and `force=true` to update resources.
+- Resources will be applied in the same order as they would be created during installation.
+- Custom Resource Definitions will still be processed first, and the system will wait for them to be established before continuing.
+
+The server-side apply approach with `force=true` ensures that resources are updated even if there are conflicts with the last applied state.
+This provides a best-effort mechanism to apply resources that follows the same flow as installation but updates resources instead of creating them.
+
+No special handling is added for specific versions or resource structures, making this a general-purpose mechanism for applying resources.
+
+## Alternatives Considered
+1. Creating a separate `upgrade` command that would duplicate much of the install command logic.
+   - Rejected due to code duplication and maintenance overhead.
+
+2. Implementing version-specific upgrade logic to handle breaking changes between versions.
+   - Rejected as overly complex and difficult to maintain across multiple version paths.
+   - This could be considered again in the future, but is not in the scope of the current design.
+
+3. Adding automatic detection of existing resources and switching to apply mode.
+   - Rejected as it could lead to unexpected behavior and confusion if users unintentionally apply changes to existing resources.
+
+## Security Considerations
+The apply flag maintains the same security profile as the install command.
+No additional permissions are required beyond what is needed for resource creation.
+The use of `force=true` with server-side apply could potentially override manual changes made to resources, but this is a necessary trade-off to ensure apply is successful.
+
+## Compatibility
+This enhancement is compatible with all existing Velero installations as it is a new opt-in flag.
+It does not change any resource formats or API contracts.
+The apply process is best-effort and does not guarantee compatibility between arbitrary versions of Velero.
+Users should still consult release notes for any breaking changes that may require manual intervention.
+This flag could be adopted by the helm chart, specifically for CRD updates, to simplify the CRD update job.
+
+## Implementation
+The implementation involves:
+1. Adding support for `Apply` to the existing Kubernetes client code.
+1. Adding the `--apply` flag to the install command options.
+1. Changing `createResource` to `createOrApplyResource` and updating it to use server-side apply when the `apply` boolean is set.
+
+The implementation is straightforward and follows existing code patterns.
+No migration of state or special handling of specific resources is required.

+# Velero Backup performance Improvements and VolumeGroupSnapshot enablement
+
+There are two different goals here, linked by a single primary missing feature in the Velero backup workflow.
+The first goal is to enhance backup performance by allowing the primary backup controller to run in multiple threads, enabling Velero to back up multiple items at the same time for a given backup.
+The second goal is to enable Velero to eventually support VolumeGroupSnapshots.
+For both of these goals, Velero needs a way to determine which items should be backed up together.
+
+This design proposal will include two development phases:
+- Phase 1 will refactor the backup workflow to identify blocks of related items that should be backed up together, and then coordinate backup hooks among items in the block.
+- Phase 2 will add multiple worker threads for backing up item blocks, so instead of backing up each block as it identified, the velero backup workflow will instead add the block to a channel and one of the workers will pick it up.
+- Actual support for VolumeGroupSnapshots is out-of-scope here and will be handled in a future design proposal, but the item block refactor introduced in Phase 1 is a primary building block for this future proposal.
+
+## Background
+Currently, during backup processing, the main Velero backup controller runs in a single thread, completely finishing the primary backup processing for one resource before moving on to the next one.
+We can improve the overall backup performance by backing up multiple items for a backup at the same time, but before we can do this we must first identify resources that need to be backed up together.
+Generally speaking, resources that need to be backed up together are resources with interdependencies -- pods with their PVCs, PVCs with their PVs, groups of pods that form a single application, CRs, pods, and other resources that belong to the same operator, etc.
+As part of this initial refactoring, once these "Item Blocks" are identified, an additional change will be to move pod hook processing up to the ItemBlock level.
+If there are multiple pods in the ItemBlock, pre-hooks for all pods will be run before backing up the items, followed by post-hooks for all pods.
+This change to hook processing is another prerequisite for future VolumeGroupSnapshot support, since supporting this will require backing up the pods and volumes together for any volumes which belong to the same group.
+Once we are backing up items by block, the next step will be to create multiple worker threads to process and back up ItemBlocks, so that we can back up multiple ItemBlocks at the same time.
+
+In looking at the different kinds of large backups that Velero must deal with, two obvious scenarios come to mind:
+1. Backups with a relatively small number of large volumes
+2. Backups with a large number of relatively small volumes.
+
+In case 1, the majority of the time spent on the backup is in the asynchronous phases -- CSI snapshot creation actions after the snaphandle exists, and DataUpload processing. In that case, parallel item processing will likely have a minimal impact on overall backup completion time.
+
+In case 2, the majority of time spent on the backup will likely be during the synchronous actions. Especially as regards CSI snapshot creation, the waiting for the VSC snaphandle to exist will result in significant passage of time with thousands of volumes. This is the sort of use case which will benefit the most from parallel item processing.
+
+## Goals
+- Identify groups of related items to back up together (ItemBlocks).
+- Manage backup hooks at the ItemBlock level rather than per-item.
+- Using worker threads, back up ItemBlocks at the same time.
+
+## Non Goals
+- Support VolumeGroupSnapshots: this is a future feature, although certain prerequisites for this enhancement are included in this proposal.
+- Process multiple backups in parallel: this is a future feature, although certain prerequisites for this enhancement are included in this proposal.
+- Refactoring plugin infrastructure to avoid RPC calls for internal plugins.
+- Restore performance improvements: this is potentially a future feature
+
+## High-Level Design
+
+### ItemBlock concept
+
+The updated design is based on a new struct/type called `ItemBlock`.
+Essentially, an `ItemBlock` is a group of items that must be backed up together in order to guarantee backup integrity.
+When we eventually split item backup across multiple worker threads, `ItemBlocks` will be kept together as the basic unit of backup.
+To facilitate this, a new plugin type, `ItemBlockAction` will allow relationships between items to be identified by velero -- any resources that must be backed up with other resources will need IBA plugins defined for them.
+Examples of `ItemBlocks` include:
+1. A pod, its mounted PVCs, and the bound PVs for those PVCs.
+2. A VolumeGroup (related PVCs and PVs) along with any pods mounting these volumes.
+3. For a ReadWriteMany PVC, the PVC, its bound PV, and all pods mounting this PVC.
+
+### Phase 1: ItemBlock processing
+- A new plugin type, `ItemBlockAction`, will be created
+- `ItemBlockAction` will contain the API method `GetRelatedItems`, which will be needed for determining which items to group together into `ItemBlocks`.
+- When processing the list of items returned from the item collector, instead of simply calling `BackupItem` on each in turn, we will use the `GetRelatedItems` API call to determine other items to include with the current item in an ItemBlock. Repeat recursively on each item returned.
+- Don't include an item in more than one ItemBlock -- if the next item from the item collector is already in a block, skip it.
+- Once ItemBlock is determined, call new func `BackupItemBlock` instead of `BackupItem`.
+- New func `BackupItemBlock` will call pre hooks for any pods in the block, then back up the items in the block (`BackupItem` will no longer run hooks directly), then call post hooks for any pods in the block.
+- The finalize phase will not be affected by the ItemBlock design, since this is just updating resources after async operations are completed on the items and there is no need to run these updates in parallel.
+
+### Phase 2: Process ItemBlocks for a single backup in multiple threads
+- Concurrent `BackupItemBlock` operations will be executed by worker threads invoked by the backup controller, which will communicate with the backup controller operation via a shared channel.
+- The ItemBlock processing loop implemented in Phase 1 will be modified to send each newly-created ItemBlock to the shared channel rather than calling `BackupItemBlock` inline.
+- Users will be able to configure the number of workers available for concurrent `BackupItemBlock` operations.
+- Access to the BackedUpItems map must be synchronized
+
+## Detailed Design
+
+### Phase 1: ItemBlock processing
+
+#### New ItemBlockAction plugin type
+
+In order for Velero to identify groups of items to back up together in an ItemBlock, we need a way to identify items which need to be backed up along with the current item. While the current `Execute` BackupItemAction method does return a list of additional items which are required by the current item, we need to know this *before* we start the item backup. To support this, we need a new plugin type, `ItemBlockAction` (IBA) with an API method, `GetRelatedItems` which Velero will call on each item as it processes. The expectation is that the registered IBA plugins will return the same items as returned as additional items by the BIA `Execute` method, with the exception that items which are not created until calling `Execute` should not be returned here, as they don't exist yet.
+
+#### Proto definition (compiled into golang by protoc)
+
+The ItemBlockAction plugin type is defined as follows:
+```
+service ItemBlockAction {
+    rpc AppliesTo(ItemBlockActionAppliesToRequest) returns (ItemBlockActionAppliesToResponse);
+    rpc GetRelatedItems(ItemBlockActionGetRelatedItemsRequest) returns (ItemBlockActionGetRelatedItemsResponse);
+}
+
+message ItemBlockActionAppliesToRequest {
+    string plugin = 1;
+}
+
+message ItemBlockActionAppliesToResponse {
+    ResourceSelector ResourceSelector = 1;
+}
+
+message ItemBlockActionGetRelatedItemsRequest {
+    string plugin = 1;
+    bytes item = 2;
+    bytes backup = 3;
+}
+
+message ItemBlockActionGetRelatedItemsResponse {
+    repeated generated.ResourceIdentifier relatedItems = 1;
+}
+```
+
+A new PluginKind, `ItemBlockAction`, will be created, and the backup process will be modified to use this plugin kind.
+
+For any BIA plugins which return additional items from `Execute()` that need to be backed up at the same time or sequentially in the same worker thread as the current items should add a new IBA plugin to return these same items (minus any which won't exist before BIA `Execute()` is called).
+This mainly applies to plugins that operate on pods which reference resources which must be backed up along with the pod and are potentially affected by pod hooks or for plugins which connect multiple pods whose volumes should be backed up at the same time.
+
+### Changes to processing item list from the Item Collector
+
+#### New structs BackupItemBlock, ItemBlock, and ItemBlockItem
+```go
+package backup
+
+type BackupItemBlock struct {
+    itemblock.ItemBlock
+    // This is a reference to the  shared itemBackupper for the backup
+    itemBackupper *itemBackupper
+}
+
+package itemblock
+
+type ItemBlock struct {
+    Log           logrus.FieldLogger
+    Items         []ItemBlockItem
+}
+
+type ItemBlockItem struct {
+    Gr           schema.GroupResource
+    Item         *unstructured.Unstructured
+    PreferredGVR schema.GroupVersionResource
+}
+```
+
+#### Current workflow
+In the `BackupWithResolvers` func, the current Velero implementation iterates over the list of items for backup returned by the Item Collector. For each item, Velero loads the item from the file created by the Item Collector, we call `backupItem`, update the GR map if successful, remove the (temporary) file containing item metadata, and update progress for the backup.
+
+#### Modifications to the loop over ItemCollector results
+The `kubernetesResource` struct used by the item collector will be modified to add an `orderedResource` bool which will be set true for all of the resources moved to the beginning for each GroupResource as a result of being ordered resources.
+In addition, an `inItemBlock` bool is added to the struct which will be set to true later when processing the list when each item is added to an ItemBlock.
+While the item collector already puts ordered resources first for each GR, there is no indication in the list which of these initial items are from the ordered resources list and which are the remaining (unordered) items.
+Velero needs to know which resources are ordered because when we process them later, the ordered resources for each GroupResource must be processed sequentially in a single ItemBlock.
+
+The current workflow within each iteration of the ItemCollector.items loop will replaced with the following:
+- (note that some of the below should be pulled out into a helper func to facilitate recursive call to it for items returned from `GetRelatedItems`.)
+- Before loop iteration, create a pointer to a `BackupItemBlock` which will represent the current ItemBlock being processed.
+- If `item` has `inItemBlock==true`, continue. This one has already been processed.
+- If current `itemBlock` is nil, create it.
+- Add `item` to `itemBlock`.
+- Load item from ItemCollector file. Close/remove file after loading (on error return or not, possibly with similar anonymous func to current impl)
+- If other versions of the same item exist (via EnableAPIGroupVersions), add these to the `itemBlock` as well (and load from ItemCollector file)
+- Get matching IBA plugins for item, call `GetRelatedItems` for each. For each item returned, get full item content from ItemCollector (if present in item list, pulling from file, removing file when done) or from cluster (if not present in item list), add item to the current block, add item to `itemsInBlock` map, and then recursively apply current step to each (i.e. call IBA method, add to block, etc.)
+- If current item and next item are both ordered items for the same GR, then continue to next item, adding to current `itemBlock`.
+- Once full ItemBlock list is generated, call `backupItemBlock(block ItemBlock)
+- Add `backupItemBlock` return values to `backedUpGroupResources` map
+
+
+#### New func `backupItemBlock`
+
+Method signature for new func `backupItemBlock` is as follows:
+```go
+func (kb *kubernetesBackupper) backupItemBlock(block BackupItemBlock) []schema.GroupResource
+```
+The return value is a slice of GRs for resources which were backed up. Velero tracks these to determine which CRDs need to be included in the backup. Note that we need to make sure we include in this not only those resources that were backed up directly, but also those backed up indirectly via additional items BIA execute returns.
+
+In order to handle backup hooks, this func will first take the input item list (`block.items`) and get a list of included pods, filtered to include only those not yet backed up (using `block.itemBackupper.backupRequest.BackedUpItems`). Iterate over this list and execute pre hooks (pulled out of `itemBackupper.backupItemInternal`) for each item.
+Now iterate over the full list (`block.items`) and call `backupItem` for each. After the first, the later items should already have been backed up, but calling a second time is harmless, since the first thing Velero does is check the `BackedUpItems` map, exiting if item is already backed up). We still need this call in case there's a plugin which returns something in `GetAdditionalItems` but forgets to return it in the `Execute` additional items return value. If we don't do this, we could end up missing items.
+
+After backing up the items in the block, we now execute post hooks using the same filtered item list we used for pre hooks, again taking the logic from `itemBackupper.backupItemInternal`).
+
+#### `itemBackupper.backupItemInternal` cleanup
+
+After implementing backup hooks in `backupItemBlock`, hook processing should be removed from `itemBackupper.backupItemInternal`.
+
+### Phase 2: Process ItemBlocks for a single backup in multiple threads
+
+#### New input field for number of ItemBlock workers
+
+The velero installer and server CLIs will get a new input field `itemBlockWorkerCount`, which will be passed along to the `backupReconciler`.
+The `backupReconciler` struct will also have this new field added. 
+
+#### Worker pool for item block processing
+
+A new type, `ItemBlockWorker` will be added which will manage a pool of worker goroutines which will process item blocks, a shared input channel for passing blocks to workers, and a WaitGroup to shut down cleanly when the reconciler exits.
+```go
+type ItemBlockWorkerPool struct {
+    itemBlockChannel chan ItemBlockInput
+    wg               *sync.WaitGroup
+    logger           logrus.FieldLogger
+}
+
+type ItemBlockInput struct {
+    itemBlock  *BackupItemBlock
+    returnChan chan ItemBlockReturn
+}
+
+type ItemBlockReturn struct {
+    itemBlock *BackupItemBlock
+    resources []schema.GroupResource
+    err       error
+}
+
+func (*p ItemBlockWorkerPool) getInputChannel() chan ItemBlockInput
+func StartItemBlockWorkerPool(context context.Context, workers int, logger logrus.FieldLogger) ItemBlockWorkerPool
+func processItemBlockWorker(context context.Context, itemBlockChannel chan ItemBlockInput, logger logrus.FieldLogger, wg *sync.WaitGroup)
+```
+
+The worker pool will be started by calling `StartItemBlockWorkerPool` in `NewBackupReconciler()`, passing in the worker count and reconciler context.
+`backupreconciler.prepareBackupRequest` will also add the input channel to the `backupRequest` so that it will be available during backup processing.
+The func `StartItemBlockWorkerPool` will create the `ItemBlockWorkerPool` with a shared buffered input channel (fixed buffer size) and start `workers` gororoutines which will each call `processItemBlockWorker`.
+The `processItemBlockWorker` func (run by the worker goroutines) will read from `itemBlockChannel`, call `BackupItemBlock` on the retrieved `ItemBlock`, and then send the return value to the retrieved `returnChan`, and then process the next block.
+
+#### Modify ItemBlock processing loop to send ItemBlocks to the worker pool rather than backing them up directly
+
+The ItemBlock processing loop implemented in Phase 1 will be modified to send each newly-created ItemBlock to the shared channel rather than calling `BackupItemBlock` inline, using a WaitGroup to manage in-process items. A separate goroutine will be created to process returns for this backup. After completion of the ItemBlock processing loop, velero will use the WaitGroup to wait for all ItemBlock processing to complete before moving forward.
+
+A simplified example of what this response goroutine might look like:
+```go
+    // omitting cancel handling, context, etc
+    ret := make(chan ItemBlockReturn)
+    wg := &sync.WaitGroup{}
+    // Handle returns
+    go func() {
+        for {
+            select {
+            case response := <-ret: // process each BackupItemBlock response
+                func() {
+                    defer wg.Done()
+                    responses = append(responses, response)
+                }()
+            case <-ctx.Done():
+                return
+            }
+        }
+    }()
+    // Simplified illustration, looping over and assumed already-determined ItemBlock list
+    for _, itemBlock := range itemBlocks {
+        wg.Add(1)
+        inputChan <- ItemBlockInput{itemBlock: itemBlock, returnChan: ret}
+    }
+    done := make(chan struct{})
+    go func() {
+        defer close(done)
+        wg.Wait()
+    }()
+    // Wait for all the ItemBlocks to be processed
+    select {
+    case <-done:
+        logger.Info("done processing ItemBlocks")
+    }
+    // responses from BackupItemBlock calls are in responses
+```
+
+When processing the responses, the main thing is to set `backedUpGroupResources[item.groupResource]=true` for each GR returned, which will give the same result as the current implementation calling items one-by-one and setting that field as needed.
+
+The ItemBlock processing loop described above will be split into two separate iterations. For the first iteration, velero will only process those items at the beginning of the loop identified as `orderedResources` -- when the groups generated from these resources are passed to the worker channel, velero will wait for the response before moving on to the next ItemBlock.
+This is to ensure that the ordered resources are processed in the required order. Once the last ordered resource is processed, the remaining ItemBlocks will be processed and sent to the worker channel without waiting for a response, in order to allow these ItemBlocks to be processed in parallel.
+The reason we must execute `ItemBlocks` with ordered resources first (and one at a time) is that this is a list of resources identified by the user as resources which must be backed up first, and in a particular order.
+
+#### Synchronize access to the BackedUpItems map
+
+Velero uses a map of BackedUpItems to track which items have already been backed up. This prevents velero from attempting to back up an item more than once, as well as guarding against creating infinite loops due to circular dependencies in the additional items returns. Since velero will now be accessing this map from the parallel goroutines, access to the map must be synchronized with mutexes.
+
+### Backup Finalize phase
+
+The finalize phase will not be affected by the ItemBlock design, since this is just updating resources after async operations are completed on the items and there is no need to run these updates in parallel.
+
+## Alternatives considered
+
+### BackpuItemAction v3 API
+
+Instead of adding a new  `ItemBlockAction` plugin type, we could add a `GetAdditionalItems` method to BackupItemAction.
+This was rejected because the new plugin type provides a cleaner interface, and keeps the function of grouping related items separate from the function of modifying item content for the backup.
+
+### Per-backup worker pool
+
+The current design makes use of a permanent worker pool, started at backup controller startup time. With this design, when we follow on with running multiple backups in parallel, the same set of workers will take ItemBlock inputs from more than one backup. Another approach that was initially considered was a temporary worker pool, created while processing a backup, and deleted upon backup completion. 
+
+#### User-visible API differences between the two approaches
+
+The main user-visible difference here is in the configuration API. For the permanent worker approach, the worker count represents the total worker count for all backups. The concurrent backup count represents the number of backups running at the same time. At any given time, though, the maximum number of worker threads backing up items concurrently is equal to the worker count. If worker count is 15 and the concurrent backup count is 3, then there will be, at most, 15 items being processed at the same time, split among up to three running backups.
+
+For the per-backup worker approach, the worker count represents the worker count for each backup. The concurrent backup count, as before, represents the number of backups running at the same time. If worker count is 15 and the concurrent backup count is 3, then there will be, at most, 45 items being processed at the same time, up to 15 for each of up to three running backups.
+#### Comparison of the two approaches
+
+- Permanent worker pool advantages:
+  - This is the more commonly-followed Kubernetes pattern. It's generally better to follow standard practices, unless there are genuine reasons for the use case to go in a different way.
+  - It's easier for users to understand the maximum number of concurrent items processed, which will have performance impact and impact on the resource requirements for the Velero pod. Users will not have to multiply the config numbers in their heads when working out how many total workers are present.
+  - It will give us more flexibility for future enhancements around concurrent backups. One possible use case: backup priority. Maybe a user wants scheduled backups to have a lower priority than user-generated backups, since a user is sitting there waiting for completion -- a shared worker pool could react to the priority by taking ItemBlocks for the higher priority backup first, which would allow a large lower-priority backup's items to be preempted by a higher-priority backup's items without needing to explicitly stop the main controller flow for that backup.
+- Per-backup worker pool advantages:
+  - Lower memory consumption than permanent worker pool, but the total memory used by a worker blocked on input will be pretty low, so if we're talking only 10-20 workers, the impact will be minimal.
+
+## Compatibility
+
+### Example IBA implementation for BIA plugins which return additional items
+
+Included below is an example of what might be required for a BIA  plugin which returns additional items.
+The code is taken from the internal velero `pod_action.go` which identifies the items required for a given pod.
+
+In this particular case, the only function of pod_action is to return additional items, so we can really just convert this plugin to an IBA plugin. If there were other actions, such as modifying the pod content on backup, then we would still need the pod action, and the related items vs. content manipulation functions would need to be separated.
+
+```go
+// PodAction implements ItemBlockAction.
+type PodAction struct {
+	log logrus.FieldLogger
+}
+
+// NewPodAction creates a new ItemAction for pods.
+func NewPodAction(logger logrus.FieldLogger) *PodAction {
+	return &PodAction{log: logger}
+}
+
+// AppliesTo returns a ResourceSelector that applies only to pods.
+func (a *PodAction) AppliesTo() (velero.ResourceSelector, error) {
+	return velero.ResourceSelector{
+		IncludedResources: []string{"pods"},
+	}, nil
+}
+
+// GetRelatedItems scans the pod's spec.volumes for persistentVolumeClaim volumes and returns a
+// ResourceIdentifier list containing references to all of the persistentVolumeClaim volumes used by
+// the pod. This ensures that when a pod is backed up, all referenced PVCs are backed up too.
+func (a *PodAction) GetRelatedItems(item runtime.Unstructured, backup *v1.Backup) (runtime.Unstructured, []velero.ResourceIdentifier, error) {
+	pod := new(corev1api.Pod)
+	if err := runtime.DefaultUnstructuredConverter.FromUnstructured(item.UnstructuredContent(), pod); err != nil {
+		return nil, errors.WithStack(err)
+	}
+
+	var relatedItems []velero.ResourceIdentifier
+	if pod.Spec.PriorityClassName != "" {
+		a.log.Infof("Adding priorityclass %s to relatedItems", pod.Spec.PriorityClassName)
+		relatedItems = append(relatedItems, velero.ResourceIdentifier{
+			GroupResource: kuberesource.PriorityClasses,
+			Name:          pod.Spec.PriorityClassName,
+		})
+	}
+
+	if len(pod.Spec.Volumes) == 0 {
+		a.log.Info("pod has no volumes")
+		return relatedItems, nil
+	}
+
+	for _, volume := range pod.Spec.Volumes {
+		if volume.PersistentVolumeClaim != nil && volume.PersistentVolumeClaim.ClaimName != "" {
+			a.log.Infof("Adding pvc %s to relatedItems", volume.PersistentVolumeClaim.ClaimName)
+
+			relatedItems = append(relatedItems, velero.ResourceIdentifier{
+				GroupResource: kuberesource.PersistentVolumeClaims,
+				Namespace:     pod.Namespace,
+				Name:          volume.PersistentVolumeClaim.ClaimName,
+			})
+		}
+	}
+
+	return relatedItems, nil
+}
+
+// API call
+func (a *PodAction) Name() string {
+	return "PodAction"
+}
+
+```
+
+
+## Implementation
+Phase 1 and Phase 2 could be implemented within the same Velero release cycle, but they need not be.
+Phase 1 is expected to be implemented in Velero 1.15.
+Phase 2 is expected to be implemented in Velero 1.16.

+# Backup PVC Configuration Design
+
+## Glossary & Abbreviation
+
+**Velero Generic Data Path (VGDP)**: VGDP is the collective modules that is introduced in [Unified Repository design][1]. Velero uses these modules to finish data transfer for various purposes (i.e., PodVolume backup/restore, Volume Snapshot Data Movement). VGDP modules include uploaders and the backup repository.  
+
+**Exposer**: Exposer is a module that is introduced in [Volume Snapshot Data Movement Design][2]. Velero uses this module to expose the volume snapshots to Velero node-agent pods or node-agent associated pods so as to complete the data movement from the snapshots.  
+
+**backupPVC**: The intermediate PVC created by the exposer for VGDP to access data from, see [Volume Snapshot Data Movement Design][2] for more details.  
+
+**backupPod**: The pod consumes the backupPVC so that VGDP could access data from the backupPVC, see [Volume Snapshot Data Movement Design][2] for more details.  
+
+**sourcePVC**: The PVC to be backed up, see [Volume Snapshot Data Movement Design][2] for more details. 
+
+## Background
+
+As elaberated in [Volume Snapshot Data Movement Design][2], a backupPVC may be created by the Exposer and the VGDP reads data from the backupPVC.  
+In some scenarios, users may need to configure some advanced settings of the backupPVC so that the data movement could work in best performance in their environments. Specifically:  
+- For some storage providers, when creating a read-only volume from a snapshot, it is very fast; whereas, if a writable volume is created from the snapshot, they need to clone the entire disk data, which is time consuming. If the backupPVC's `accessModes` is set as `ReadOnlyMany`, the volume driver is able to tell the storage to create a read-only volume, which may dramatically shorten the snapshot expose time. On the other hand,  `ReadOnlyMany` is not supported by all volumes. Therefore, users should be allowed to configure the `accessModes` for the backupPVC.  
+- Some storage providers create one or more replicas when creating a volume, the number of replicas is defined in the storage class. However, it doesn't make any sense to keep replicas when an intermediate volume used by the backup. Therefore, users should be allowed to configure another storage class specifically used by the backupPVC.  
+
+## Goals
+
+- Create a mechanism for users to specify various configurations for backupPVC    
+
+## Non-Goals
+
+## Solution
+
+We will use the ConfigMap specified by `velero node-agent` CLI's parameter `--node-agent-configmap` to host the backupPVC configurations.
+This configMap is not created by Velero, users should create it manually on demand. The configMap should be in the same namespace where Velero is installed. If multiple Velero instances are installed in different namespaces, there should be one configMap in each namespace which applies to node-agent in that namespace only.  
+Node-agent server checks these configurations at startup time and use it to initiate the related Exposer modules. Therefore, users could edit this configMap any time, but in order to make the changes effective, node-agent server needs to be restarted.  
+Inside the ConfigMap we will add one new kind of configuration as the data in the configMap, the name is ```backupPVC```.  
+Users may want to set different backupPVC configurations for different volumes, therefore, we define the configurations as a map and allow users to specific configurations by storage class. Specifically, the key of the map element is the storage class name used by the sourcePVC and the value is the set of configurations for the backupPVC created for the sourcePVC.   
+
+The data structure is as below:
+```go
+type Configs struct {
+	// LoadConcurrency is the config for data path load concurrency per node.
+	LoadConcurrency *LoadConcurrency `json:"loadConcurrency,omitempty"`
+
+	// LoadAffinity is the config for data path load affinity.
+	LoadAffinity []*LoadAffinity `json:"loadAffinity,omitempty"`
+
+	// BackupPVC is the config for backupPVC of snapshot data movement.
+	BackupPVC map[string]BackupPVC `json:"backupPVC,omitempty"`
+}
+
+type BackupPVC struct {
+	// StorageClass is the name of storage class to be used by the backupPVC.
+	StorageClass string `json:"storageClass,omitempty"`
+
+	// ReadOnly sets the backupPVC's access mode as read only.
+	ReadOnly bool `json:"readOnly,omitempty"`
+}
+```  
+
+### Sample
+A sample of the ConfigMap is as below:
+```json
+{
+    "backupPVC": {
+        "storage-class-1": {
+            "storageClass": "snapshot-storage-class",
+            "readOnly": true
+        },
+        "storage-class-2": {
+            "storageClass": "snapshot-storage-class"
+        },
+        "storage-class-3": {
+            "readOnly": true
+        }        
+    }
+}
+```
+
+To create the configMap, users need to save something like the above sample to a json file and then run below command:
+```
+kubectl create cm <ConfigMap name> -n velero --from-file=<json file name>
+``` 
+
+### Implementation
+The `backupPVC` is passed to the exposer and the exposer sets the related specification and create the backupPVC.  
+If `backupPVC.storageClass` doesn't exist or set as empty, the sourcePVC's storage class will be used.  
+If `backupPVC.readOnly` is set to true, `ReadOnlyMany` will be the only value set to the backupPVC's `accessModes`, otherwise, `ReadWriteOnce` is used.  
+
+Once `backupPVC.storageClass` is set, users must make sure that the specified storage class exists in the cluster and can be used the the backupPVC, otherwise, the corresponding DataUpload CR will stay in `Accepted` phase until the prepare timeout (by default 30min).   
+Once `backupPVC.readOnly` is set to true, users must make sure that the storage supports to create a `ReadOnlyMany` PVC from a snapshot, otherwise, the corresponding DataUpload CR will stay in `Accepted` phase until the prepare timeout (by default 30min).  
+
+Once above problems happen, the DataUpload CR is cancelled after prepare timeout and the backupPVC and backupPod will be deleted, so there is no way to tell the cause is one of the above problems or others.  
+To help the troubleshooting, we can add some diagnostic mechanism to discover the status of the backupPod before deleting it as a result of the prepare timeout.

+# Backup Repository Cache Volume Design
+
+## Glossary & Abbreviation
+
+**Backup Storage**: The storage to store the backup data. Check [Unified Repository design][1] for details.  
+**Backup Repository**: Backup repository is layered between BR data movers and Backup Storage to provide BR related features that is introduced in [Unified Repository design][1].  
+**Velero Generic Data Path (VGDP)**: VGDP is the collective of modules that is introduced in [Unified Repository design][1]. Velero uses these modules to finish data transfer for various purposes (i.e., PodVolume backup/restore, Volume Snapshot Data Movement). VGDP modules include uploaders and the backup repository.  
+**Data Mover Pods**: Intermediate pods which hold VGDP and complete the data transfer. See [VGDP Micro Service for Volume Snapshot Data Movement][2] and [VGDP Micro Service For fs-backup][3] for details.  
+**Repository Maintenance Pods**: Pods for [Repository Maintenance Jobs][4], which holds VGDP to run repository maintenance.    
+
+## Background
+
+According to the [Unified Repository design][1] Velero uses selectable backup repositories for various backup/restore methods, i.e., fs-backup, volume snapshot data movement, etc. Some backup repositories may need to cache data on the client side for various repository operation, so as to accelerate the execution.  
+In the existing [Backup Repository Configuration][5], we allow users to configure the cache data size (`cacheLimitMB`). However, the cache data is still stored in the root file system of data mover pods/repository maintenance pods, so stored in the root file system of the node. This is not good enough, reasons:  
+- In many distributions, the node's system disk size is predefined, non configurable and limit, e.g., the system disk size may be 20G or less
+- Velero supports concurrent data movements in each node. The cache in each of the concurrent data mover pods could quickly run out of the system disk and cause problems like pod eviction, failure of pod creation, degradation of Kubernetes QoS, etc.  
+
+We need to allow users to prepare a dedicated location, e.g., a dedictated volume, for the cache.  
+Not all backup repositories or not all backup repository operations require cache, we need to define the details when and how the cache is used.  
+
+## Goals
+
+- Create a mechanism for users to configure cache volumes for various pods running VGDP
+- Design the workflow to assign the cache volume pod path to backup repositories
+- Describe when and how the cache volume is used 
+
+## Non-Goals
+
+- The solution is based on [Unified Repository design][1], [VGDP Micro Service for Volume Snapshot Data Movement][2] and [VGDP Micro Service For fs-backup][3], legacy data paths are not supported. E.g., when a pod volume restore (PVR) runs with legacy Restic path, if any data is cached, the cache still resides in the root file system.  
+
+## Solution
+
+### Cache Data
+
+Varying on backup repositoires, cache data may include payload data or repository metadata, e.g., indexes to the payload data chunks.  
+
+Payload data is highly related to the backup data, and normally take the majority of the repository data as well as the cache data.
+
+Repository metadata is related to the backup repository's chunking algorithm, data chunk mapping method, etc, and so the size is not proportional to the backup data size.  
+On the other hand for some backup repository, in extreme cases, the repository metadata may be significantly large. E.g., Kopia's indexes are per chunks, if there are huge number of small files in the repository, Kopia's index data may be in the same level of or even larger than the payload data.    
+However, in the cases that repository metadata data become the majority, other bottlenecks may emerge and concurrency of data movers may be significantly constrained, so the requirement to cache volumes may go away.  
+
+Therefore, for now we only consider the cache volume requirement for payload data, and leave the consideration for metadata as a future enhancement.  
+
+### Scenarios
+
+Backup repository cache varies on backup repositories and backup repository operation during VGDP runs. Below are the scenarios when VGDP runs:
+- Data Upload for Backup: this is the process to upload/write the backup data into the backup repository, e.g., DataUpload or PodVolumeBackup. The pieces of data is almost directly written to the repository, sometimes with a small group staying shortly in the local place. That is to say, there should not be large scale data cached for this scenario, so we don't prepare dedicated cache for this scenario.
+- Repository Maintenance: Repository maintenance most often visits the backup repository's metadata and sometimes it needs to visit the file system directories from the backed up data. On the other hand, it is not practical to run concurrent maintenance jobs in one node. So the cache data is neither large nor affect the root file system too much. Therefore, we don't need to prepare dedicated cache for this scenario.
+- Data Download for Restore: this is the process to download/read the backup data from the backup repository during restore, e.g., DataDownload or PodVolumeRestore. For backup repositories for which data are stored in remote backup storages (e.g., Kopia repository stores data in remote object stores), large scale of data are cached locally to accerlerate the restore. Therefore, we need dedicate cache volumes for this scenario.  
+- Backup Deletion: During this scenario, backup repository is connected, metadata is enumerated to find the repository snapshot representing the backup data. That is to say, only metadata is cached if any. Therefore, dedicated cache volumes are not required in this scenario.
+
+The above analyses are based on the common behavior of backup repositories and they are not considering the case that backup repository metadata takes majority or siginficant proportion of the cache data.   
+As a conclusion of the analyses, we will create dedicated cache volumes for restore scenarios.  
+For other scenarios, we can add them regarded to the future changes/requirements. The mechanism to expose and connect the cache volumes should work for all scenarios. E.g., if we need to consider the backup repository metadata case, we may need cache volumes for backup and repository maintenance as well, then we can just reuse the same cache volume provision and connection mechanism to backup and repository maintenance scenarios.   
+
+### Cache Data and Lifecycle
+
+If available, one cache volume is dedicately assigned to one data mover pod. That is, the cached data is destroyed when the data mover pod completes. Then the backup repository instance also closes.    
+Cache data are fully managed by the specific backup repository. So the backup repository may also have its own way to GC the cache data.  
+That is to say, cache data GC may be launched by the backup repository instance during the running of the data mover pod; then the left data are automatically destroyed when the data mover pod and the cache PVC are destroyed (cache PVC's `reclaimPolicy` is always `Deleted`, so once the cache PVC is destroyed, the volume will also be destroyed). So no specially logics are needed for cache data GC.  
+
+### Data Size
+
+Cache volumes take storage space and cluster resources (PVC, PV), therefore, cache volumes should be created only when necessary and the volumes should be with reasonable size based on the cache data size:  
+- It is not a good bargain to have cache volumes for small backups, small backups will use resident cache location (the cache location in the root file system)
+- The cache data size has a limit, the existing `cacheLimitMB` is used for this purpose. E.g., it could be set as 1024 for a 1TB backup, which means 1GB of data is cached and the old cache data exceeding this size will be cleared. Therefore, it is meaningless to set the cache volume size much larger than `cacheLimitMB`
+
+### Cache Volume Size
+
+The cache volume size is calculated from below factors (for Restore scenarios):  
+- **Limit**: The limit of the cache data, that is represented by `cacheLimitMB`, the default value is 5GB
+- **backupSize**: The size of the backup as a reference to evaluate whether to create a cache volume. It doesn't mean the backup data really decides the cache data all the time, it is just a reference to evaluate the scale of the backup, small scale backups may need small cache data. Sometimes, backupSize is not irrelevant to the size of cache data, in this case, ResidentThreshold should not be set, Limit will be used directly. It is unlikely that backupSize is unavailable, but once that happens, ResidentThreshold is ignored, Limit will be used directly.  
+- **ResidentThreshold**: The minimum backup size that a cache volume is created
+- **InflationPercentage**: Considering the overhead of the file system and the possible delay of the cache cleanup, there should be an inflation for the final volume size vs. the logical size, otherwise, the cache volume may be overrun. This inflation percentage is hardcoded, e.g., 20%. 
+
+A formula is as below:  
+```
+cacheVolumeSize = ((backupSize != 0 ? (backupSize > residentThreshold ? limit : 0) : limit) * (100 + inflationPercentage)) / 100
+```
+Finally, the `cacheVolumeSize` will be rounded up to GiB considering the UX friendliness, storage friendliness and management friendliness.    
+
+### PVC/PV
+
+The PVC for a cache volume is created in Velero namespace and a storage class is required for the cache PVC. The PVC's accessMode is `ReadWriteOnce` and volumeMode is `FileSystem`, so the storage class provided should support this specification. Otherwise, if the storageclass doesn't support either of the specifications, the data mover pod may be hang in `Pending` state until a timeout setting with the data movement (e.g. `prepareTimeout`) and the data movement will finally fail.  
+It is not expected that the cache volume is retained after data mover pod is deleted, so the `reclaimPolicy` for the storageclass must be `Delete`.  
+
+To detect the problems in the storageclass and fail earlier, a validation is applied to the storageclass and once the validation fails, the cache configuration will be ignored, so the data mover pod will be created without a cache volume.  
+
+### Cache Volume Configurations
+
+Below configurations are introduced:
+- **residentThresholdMB**: the minimum data size(in MB) to be processed (if available) that a cache volume is created
+- **cacheStorageClass**: the name of the storage class to provision the cache PVC
+
+Not like `cacheLimitMB` which is set to and affect the backup repository, the above two configurations are actually data mover configurations of how to create cache volumes to data mover pods; and the two configurations don't need to be per backup repository. So we add them to the node-agent Configuration.  
+
+### Sample
+
+Below are some examples of the node-agent configMap with the configurations:
+
+Sample-1:  
+```json
+{
+    "cacheVolume": {
+        "storageClass": "sc-1",
+        "residentThresholdMB": 1024        
+    }
+}
+```
+
+Sample-2:  
+```json
+{
+    "cacheVolume": {
+        "storageClass": "sc-1",       
+    }
+}
+```
+
+Sample-3:  
+```json
+{
+    "cacheVolume": {
+        "residentThresholdMB": 1024        
+    }
+}
+```
+
+**sample-1**: This is a valid configuration. Restores with backup data size larger than 1G will be assigned a cache volume using storage class `sc-1`.  
+**sample-2**: This is a valid configuration. Data mover pods are always assigned a cache volume using storage class `sc-1`.  
+**sample-3**: This is not a valid configuration because the storage class is absent. Velero gives up creating a cache volume.   
+
+To create the configMap, users need to save something like the above sample to a json file and then run below command:
+```
+kubectl create cm <ConfigMap name> -n velero --from-file=<json file name>
+```
+
+The cache volume configurations will be visited by node-agent server, so they also need to specify the `--node-agent-configmap` to the `velero node-agent` parameters.  
+
+## Detailed Design
+
+### Backup and Restore
+
+The restore needs to know the backup size so as to calculate the cache volume size, some new fields are added to the DataDownload and PodVolumeRestore CRDs.  
+
+`snapshotSize` field is also added to DataDownload and PodVolumeRestore's `spec`:
+```yaml
+          spec:
+              snapshotID:
+                description: SnapshotID is the ID of the Velero backup snapshot to
+                  be restored from.
+                type: string
+              snapshotSize:
+                description: SnapshotSize is the logical size of the snapshot.
+                format: int64
+                type: integer
+```
+
+`snapshotSize` represents the total size of the backup; during restore, the value is transferred from DataUpload/PodVolumeBackup's `Status.Progress.TotalBytes` to DataDownload/PodVolumeRestore.    
+
+It is unlikely that `Status.Progress.TotalBytes` from DataUpload/PodVolumeBackup is unavailable, but once it happens, according to the above formula, `residentThresholdMB` is ignored, cache volume size is calculated directly from cache limit for the corresponding backup repository.  
+
+### Exposer
+
+Cache volume configurations are retrieved by node-agent and passed through DataDownload/PodVolumeRestore to GenericRestore exposer/PodVolume exposer.  
+The exposers are responsible to calculate cache volume size, create cache PVCs and mount them to the restorePods.  
+If the calculated cache volume size is 0, or any of the critical parameters is missing (e.g., cache volume storage class), the exposers ignore the cache volume configuration and continue with creating restorePods without cache volumes, so no impact to the result of the restore.  
+
+Exposers mount the cache volume to a predefined directory and pass the directory to the data mover pods through the `cache-volume-path` parameter.  
+
+Below data structure is added to the exposers' expose parameters:  
+
+```go
+type GenericRestoreExposeParam struct {
+	// RestoreSize specifies the data size for the volume to be restored
+	RestoreSize int64
+
+	// CacheVolume specifies the info for cache volumes
+	CacheVolume *CacheVolumeInfo
+}
+
+type PodVolumeExposeParam struct {
+	// RestoreSize specifies the data size for the volume to be restored
+	RestoreSize int64
+
+	// CacheVolume specifies the info for cache volumes
+	CacheVolume *repocache.CacheConfigs
+}
+
+type CacheConfigs struct {
+	// StorageClass specifies the storage class for cache volumes
+	StorageClass string
+
+	// Limit specifies the maximum size of the cache data
+	Limit int64
+
+	// ResidentThreshold specifies the minimum size of the cache data to create a cache volume
+	ResidentThreshold int64
+}
+```
+
+### Data Mover Pods
+
+Data mover pods retrieve the cache volume directory from `cache-volume-path` parameter and pass it to Unified Repository.  
+If the directory is empty, Unified Repository uses the resident location for data cache, that is, the root file system.  
+
+### Kopia Repository
+
+Kopia repository supports cache directory configuration for both metadata and data. The existing `SetupConnectOptions` is modified to customize the `CacheDirectory`:  
+
+```go
+func SetupConnectOptions(ctx context.Context, repoOptions udmrepo.RepoOptions) repo.ConnectOptions {
+    ...
+
+	return repo.ConnectOptions{
+		CachingOptions: content.CachingOptions{
+			CacheDirectory: cacheDir,
+			...
+		},
+		...
+	}
+}
+```

+# Backup Repository Configuration Design
+
+## Glossary & Abbreviation
+
+**Backup Storage**: The storage to store the backup data. Check [Unified Repository design][1] for details.  
+**Backup Repository**: Backup repository is layered between BR data movers and Backup Storage to provide BR related features that is introduced in [Unified Repository design][1].    
+
+## Background
+
+According to the [Unified Repository design][1] Velero uses selectable backup repositories for various backup/restore methods, i.e., fs-backup, volume snapshot data movement, etc. To achieve the best performance, backup repositories may need to be configured according to the running environments.  
+For example, if there are sufficient CPU and memory resources in the environment, users may enable compression feature provided by the backup repository, so as to achieve the best backup throughput.  
+As another example, if the local disk space is not sufficient, users may want to constraint the backup repository's cache size, so as to prevent the repository from running out of the disk space.  
+Therefore, it is worthy to allow users to configure some essential parameters of the backup repsoitories, and the configuration may vary from backup repositories.  
+
+## Goals
+
+- Create a mechanism for users to specify configurations for backup repositories  
+
+## Non-Goals
+
+## Solution
+
+### BackupRepository CRD
+
+After a backup repository is initialized, a BackupRepository CR is created to represent the instance of the backup repository. The BackupRepository's spec is a core parameter used by Unified Repo modules when interactive with the backup repsoitory. Therefore, we can add the configurations into the BackupRepository CR called ```repositoryConfig```.  
+The configurations may be different varying from backup repositories, therefore, we will not define each of the configurations explicitly. Instead, we add a map in the BackupRepository's spec to take any configuration to be set to the backup repository.  
+
+During various operations to the backup repository, the Unified Repo modules will retrieve from the map for the specific configuration that is required at that time. So even though it is specified, a configuration may not be visited/hornored if the operations don't require it for the specific backup repository, this won't bring any issue. When and how a configuration is hornored is decided by the configuration itself and should be clarified in the configuration's specification.  
+
+Below is the new BackupRepository's spec after adding the configuration map:  
+```yaml
+          spec:
+            description: BackupRepositorySpec is the specification for a BackupRepository.
+            properties:
+              backupStorageLocation:
+                description: |-
+                  BackupStorageLocation is the name of the BackupStorageLocation
+                  that should contain this repository.
+                type: string
+              maintenanceFrequency:
+                description: MaintenanceFrequency is how often maintenance should
+                  be run.
+                type: string
+              repositoryConfig:
+                additionalProperties:
+                  type: string
+                description: RepositoryConfig contains configurations for the specific
+                  repository.
+                type: object
+              repositoryType:
+                description: RepositoryType indicates the type of the backend repository
+                enum:
+                - kopia
+                - restic
+                - ""
+                type: string
+              resticIdentifier:
+                description: |-
+                  ResticIdentifier is the full restic-compatible string for identifying
+                  this repository.
+                type: string
+              volumeNamespace:
+                description: |-
+                  VolumeNamespace is the namespace this backup repository contains
+                  pod volume backups for.
+                type: string
+            required:
+            - backupStorageLocation
+            - maintenanceFrequency
+            - resticIdentifier
+            - volumeNamespace
+            type: object
+```            
+
+### BackupRepository configMap
+
+The BackupRepository CR is not created explicitly by a Velero CLI, but created as part of the backup/restore/maintenance operation if the CR doesn't exist. As a result, users don't have any way to specify the configurations before the BackupRepository CR is created.  
+Therefore, a BackupRepository configMap is introduced as a template of the configurations to be applied to the backup repository CR.  
+When the backup repository CR is created by the BackupRepository controller, the configurations in the configMap are copied to the ```repositoryConfig``` field.   
+For an existing BackupRepository CR, the configMap is never visited, if users want to modify the configuration value, they should directly edit the BackupRepository CR.  
+
+The BackupRepository configMap is created by users in velero installation namespace. The configMap name must be specified in the velero server parameter ```--backup-repository-configmap```, otherwise, it won't effect.  
+If the configMap name is specified but the configMap doesn't exist by the time of a backup repository is created, the configMap name is ignored.  
+For any reason, if the configMap doesn't effect, nothing is specified to the backup repository CR, so the Unified Repo modules use the hard-coded values to configure the backup repository.  
+
+The BackupRepository configMap supports backup repository type specific configurations, even though users can only specify one configMap.  
+So in the configMap struct, multiple entries are supported, indexed by the backup repository type. During the backup repository creation, the configMap is searched by the repository type.  
+
+### Configurations
+
+With the above mechanisms, any kind of configuration could be added. Here list the configurations defined at present:  
+```cacheLimitMB```: specifies the size limit(in MB) for the local data cache. The more data is cached locally, the less data may be downloaded from the backup storage, so the better performance may be achieved. Practically, users can specify any size that is smaller than the free space so that the disk space won't run out. This parameter is for each repository connection, that is, users could change it before connecting to the repository. If a backup repository doesn't use local cache, this parameter will be ignored. For Kopia repository, this parameter is supported.  
+```enableCompression```: specifies to enable/disable compression for a backup repsotiory. Most of the backup repositories support the data compression feature, if it is not supported by a backup repository, this parameter is ignored. Most of the backup repositories support to dynamically enable/disable compression, so this parameter is defined to be used whenever creating a write connection to the backup repository, if the dynamically changing is not supported, this parameter will be hornored only when initializing the backup repository. For Kopia repository, this parameter is supported and can be dynamically modified.  
+
+### Sample
+Below is an example of the BackupRepository configMap with the configurations:     
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: <config-name>
+  namespace: velero
+data:
+  <repository-type-1>: |
+    {
+      "cacheLimitMB": 2048,
+      "enableCompression": true    
+    }
+  <repository-type-2>: |
+    {
+      "cacheLimitMB": 1,
+      "enableCompression": false    
+    }        
+```
+
+To create the configMap, users need to save something like the above sample to a file and then run below commands:  
+```
+kubectl apply -f <yaml file name>
+```

+# Design for BSL Certificate Support Enhancement
+
+## Abstract
+
+This design document describes the enhancement of BackupStorageLocation (BSL) certificate management in Velero, introducing a Secret-based certificate reference mechanism (`caCertRef`) alongside the existing inline certificate field (`caCert`). This enhancement provides a more secure, Kubernetes-native approach to certificate management while enabling future CLI improvements for automatic certificate discovery.
+
+## Background
+
+Currently, Velero supports TLS certificate verification for object storage providers through an inline `caCert` field in the BSL specification. While functional, this approach has several limitations:
+
+- **Security**: Certificates are stored directly in the BSL YAML, potentially exposing sensitive data
+- **Management**: Certificate rotation requires updating the BSL resource itself
+- **CLI Usability**: Users must manually specify certificates when using CLI commands
+- **Size Limitations**: Large certificate bundles can make BSL resources unwieldy
+
+Issue #9097 and PR #8557 highlight the need for improved certificate management that addresses these concerns while maintaining backward compatibility.
+
+## Goals
+
+- Provide a secure, Secret-based certificate storage mechanism
+- Maintain full backward compatibility with existing BSL configurations
+- Enable future CLI enhancements for automatic certificate discovery
+- Simplify certificate rotation and management
+- Provide clear migration path for existing users
+
+## Non-Goals
+
+- Removing support for inline certificates immediately
+- Changing the behavior of existing BSL configurations
+- Implementing client-side certificate validation
+- Supporting certificates from ConfigMaps or other resource types
+
+## High-Level Design
+
+### API Changes
+
+#### New Field: CACertRef
+
+```go
+type ObjectStorageLocation struct {
+    // Existing field (now deprecated)
+    // +optional
+    // +kubebuilder:deprecatedversion:warning="caCert is deprecated, use caCertRef instead"
+    CACert []byte `json:"caCert,omitempty"`
+
+    // New field for Secret reference
+    // +optional
+    CACertRef *corev1api.SecretKeySelector `json:"caCertRef,omitempty"`
+}
+```
+
+The `SecretKeySelector` follows standard Kubernetes patterns:
+```go
+type SecretKeySelector struct {
+    // Name of the Secret
+    Name string `json:"name"`
+    // Key within the Secret
+    Key string `json:"key"`
+}
+```
+
+### Certificate Resolution Logic
+
+The system follows a priority-based resolution:
+
+1. If `caCertRef` is specified, retrieve certificate from the referenced Secret
+2. If `caCert` is specified (and `caCertRef` is not), use the inline certificate
+3. If neither is specified, no custom CA certificate is used
+
+### Validation
+
+BSL validation ensures mutual exclusivity:
+```go
+func (bsl *BackupStorageLocation) Validate() error {
+    if bsl.Spec.ObjectStorage != nil &&
+        bsl.Spec.ObjectStorage.CACert != nil &&
+        bsl.Spec.ObjectStorage.CACertRef != nil {
+        return errors.New("cannot specify both caCert and caCertRef in objectStorage")
+    }
+    return nil
+}
+```
+
+## Detailed Design
+
+### BSL Controller Changes
+
+The BSL controller incorporates validation during reconciliation:
+
+```go
+func (r *backupStorageLocationReconciler) Reconcile(req ctrl.Request) (ctrl.Result, error) {
+    // ... existing code ...
+    
+    // Validate BSL configuration
+    if err := location.Validate(); err != nil {
+        r.logger.WithError(err).Error("BSL validation failed")
+        return ctrl.Result{}, err
+    }
+    
+    // ... continue reconciliation ...
+}
+```
+
+### Repository Provider Integration
+
+All repository providers implement consistent certificate handling:
+
+```go
+func configureCACert(bsl *velerov1api.BackupStorageLocation, credGetter *credentials.CredentialGetter) ([]byte, error) {
+    if bsl.Spec.ObjectStorage == nil {
+        return nil, nil
+    }
+
+    // Prefer caCertRef (new method)
+    if bsl.Spec.ObjectStorage.CACertRef != nil {
+        certString, err := credGetter.FromSecret.Get(bsl.Spec.ObjectStorage.CACertRef)
+        if err != nil {
+            return nil, errors.Wrap(err, "error getting CA certificate from secret")
+        }
+        return []byte(certString), nil
+    }
+
+    // Fall back to caCert (deprecated)
+    if bsl.Spec.ObjectStorage.CACert != nil {
+        return bsl.Spec.ObjectStorage.CACert, nil
+    }
+
+    return nil, nil
+}
+```
+
+### CLI Certificate Discovery Integration
+
+#### Background: PR #8557 Implementation
+PR #8557 ("CLI automatically discovers and uses cacert from BSL") was merged in August 2025, introducing automatic CA certificate discovery from BackupStorageLocation for Velero CLI download operations. This eliminated the need for users to manually specify the `--cacert` flag when performing operations like `backup describe`, `backup download`, `backup logs`, and `restore logs`.
+
+#### Current Implementation (Post PR #8557)
+The CLI now automatically discovers certificates from BSL through the `pkg/cmd/util/cacert/bsl_cacert.go` module:
+
+```go
+// Current implementation only supports inline caCert
+func GetCACertFromBSL(ctx context.Context, client kbclient.Client, namespace, bslName string) (string, error) {
+    // ... fetch BSL ...
+    if bsl.Spec.ObjectStorage != nil && len(bsl.Spec.ObjectStorage.CACert) > 0 {
+        return string(bsl.Spec.ObjectStorage.CACert), nil
+    }
+    return "", nil
+}
+```
+
+#### Enhancement with caCertRef Support
+This design extends the existing CLI certificate discovery to support the new `caCertRef` field:
+
+```go
+// Enhanced implementation supporting both caCert and caCertRef
+func GetCACertFromBSL(ctx context.Context, client kbclient.Client, namespace, bslName string) (string, error) {
+    // ... fetch BSL ...
+
+    // Prefer caCertRef over inline caCert
+    if bsl.Spec.ObjectStorage.CACertRef != nil {

+
+#### Certificate Resolution Priority
+
+The CLI follows this priority order for certificate resolution:
+
+1. **`--cacert` flag** - Manual override, highest priority
+2. **`caCertRef`** - Secret-based certificate (recommended)
+3. **`caCert`** - Inline certificate (deprecated)
+4. **System certificate pool** - Default fallback
+
+#### User Experience Improvements
+
+With both PR #8557 and this enhancement:
+
+```bash
+# Automatic discovery - works with both caCert and caCertRef
+velero backup describe my-backup
+velero backup download my-backup
+velero backup logs my-backup
+velero restore logs my-restore
+
+# Manual override still available
+velero backup describe my-backup --cacert /custom/ca.crt
+
+# Debug output shows certificate source
+velero backup download my-backup --log-level=debug
+# [DEBUG] Resolved CA certificate from BSL 'default' Secret 'storage-ca-cert' key 'ca-bundle.crt'
+```
+
+#### RBAC Considerations for CLI
+
+CLI users need read access to Secrets when using `caCertRef`:
+
+```yaml
+apiVersion: rbac.authorization.k8s.io/v1
+kind: Role
+metadata:
+  name: velero-cli-user
+  namespace: velero
+rules:
+- apiGroups: ["velero.io"]
+  resources: ["backups", "restores", "backupstoragelocations"]
+  verbs: ["get", "list"]
+- apiGroups: [""]
+  resources: ["secrets"]
+  verbs: ["get"]
+  # Limited to secrets referenced by BSLs
+```
+
+### Migration Strategy
+
+#### Phase 1: Introduction (Current)
+- Add `caCertRef` field
+- Mark `caCert` as deprecated
+- Both fields supported, mutual exclusivity enforced
+
+#### Phase 2: Migration Period
+- Documentation and tools to help users migrate
+- Warning messages for `caCert` usage
+- CLI enhancements to leverage `caCertRef`
+
+#### Phase 3: Future Removal
+- Remove `caCert` field in major version update
+- Provide migration tool for automatic conversion
+
+## User Experience
+
+### Creating a BSL with Certificate Reference
+
+1. Create a Secret containing the CA certificate:
+```yaml
+apiVersion: v1
+kind: Secret
+metadata:
+  name: storage-ca-cert
+  namespace: velero
+type: Opaque
+data:
+  ca-bundle.crt: <base64-encoded-certificate>
+```
+
+2. Reference the Secret in BSL:
+```yaml
+apiVersion: velero.io/v1
+kind: BackupStorageLocation
+metadata:
+  name: default
+  namespace: velero
+spec:
+  provider: aws
+  objectStorage:
+    bucket: my-bucket
+    caCertRef:
+      name: storage-ca-cert
+      key: ca-bundle.crt
+```
+
+### Certificate Rotation
+
+With Secret-based certificates:
+```bash
+# Update the Secret with new certificate
+kubectl create secret generic storage-ca-cert \
+  --from-file=ca-bundle.crt=new-ca.crt \
+  --dry-run=client -o yaml | kubectl apply -f -
+
+# No BSL update required - changes take effect on next use
+```
+
+### CLI Usage Examples
+
+#### Immediate Benefits
+- No change required for existing workflows
+- Certificate validation errors include helpful context
+
+#### Future CLI Enhancements
+```bash
+# Automatic certificate discovery
+velero backup download my-backup
+
+# Manual override still available
+velero backup download my-backup --cacert /custom/ca.crt
+
+# Debug certificate resolution
+velero backup download my-backup --log-level=debug
+# [DEBUG] Resolved CA certificate from BSL 'default' Secret 'storage-ca-cert'
+```
+
+## Security Considerations
+
+### Advantages of Secret-based Storage
+
+1. **Encryption at Rest**: Secrets are encrypted in etcd
+2. **RBAC Control**: Fine-grained access control via Kubernetes RBAC
+3. **Audit Trail**: Secret access is auditable
+4. **Separation of Concerns**: Certificates separate from configuration
+
+### Required Permissions
+
+The Velero server requires additional RBAC permissions:
+```yaml
+- apiGroups: [""]
+  resources: ["secrets"]
+  verbs: ["get"]
+  # Scoped to secrets referenced by BSLs
+```
+
+## Compatibility
+
+### Backward Compatibility
+
+- Existing BSLs with `caCert` continue to function unchanged
+- No breaking changes to API
+- Gradual migration path
+
+### Forward Compatibility
+
+- Design allows for future enhancements:
+  - Multiple certificate support
+  - Certificate chain validation
+  - Automatic certificate discovery from cloud providers
+
+## Implementation Phases
+
+### Phase 1: Core Implementation ✓ (Current PR)
+- API changes with new `caCertRef` field
+- Controller validation
+- Repository provider updates
+- Basic testing
+
+### Phase 2: CLI Enhancement (Future)
+- Automatic certificate discovery in CLI
+- Enhanced error messages
+- Debug logging for certificate resolution
+
+### Phase 3: Migration Tools (Future)
+- Automated migration scripts
+- Validation tools
+- Documentation updates
+
+## Testing
+
+### Unit Tests
+- BSL validation logic
+- Certificate resolution in providers
+- Controller behavior
+
+### Integration Tests
+- End-to-end backup/restore with `caCertRef`
+- Certificate rotation scenarios
+- Migration from `caCert` to `caCertRef`
+
+### Manual Testing Scenarios
+1. Create BSL with `caCertRef`
+2. Perform backup/restore operations
+3. Rotate certificate in Secret
+4. Verify continued operation
+
+## Documentation
+
+### User Documentation
+- Migration guide from `caCert` to `caCertRef`
+- Examples for common cloud providers
+- Troubleshooting guide
+
+### API Documentation
+- Updated API reference
+- Deprecation notices
+- Field descriptions
+
+## Alternatives Considered
+
+### ConfigMap-based Storage
+- Pros: Similar to Secrets, simpler API
+- Cons: Not designed for sensitive data, no encryption at rest
+- Decision: Secrets are the Kubernetes-standard for sensitive data
+
+### External Certificate Management
+- Pros: Integration with cert-manager, etc.
+- Cons: Additional complexity, dependencies
+- Decision: Keep it simple, allow users to manage certificates as needed
+
+### Immediate Removal of Inline Certificates
+- Pros: Cleaner API, forces best practices
+- Cons: Breaking change, migration burden
+- Decision: Gradual deprecation respects existing users
+
+## Conclusion
+
+This design provides a secure, Kubernetes-native approach to certificate management in Velero while maintaining backward compatibility. It establishes the foundation for enhanced CLI functionality and improved user experience, addressing the concerns raised in issue #9097 and enabling the features proposed in PR #8557.
+
+The phased approach ensures smooth migration for existing users while delivering immediate security benefits for new deployments.

+# Design to clean the artifacts generated in the CSI backup and restore workflows
+
+## Terminology
+
+* VSC: VolumeSnapshotContent
+* VS: VolumeSnapshot
+
+## Abstract
+* The design aims to delete the unnecessary VSs and VSCs generated during CSI backup and restore process. 
+* The design stop creating related VSCs during backup syncing.
+
+## Background
+In the current CSI backup and restore workflows, please notice the CSI B/R workflows means only using the CSI snapshots in the B/R, not including the CSI snapshot data movement workflows, some generated artifacts are kept after the backup or the restore process completion.
+
+Some of them are kept due to design, for example, the VolumeSnapshotContents generated during the backup are kept to make sure the backup deletion can clean the snapshots in the storage providers.
+
+Some of them are kept by accident, for example, after restore, two VolumeSnapshotContents are generated for the same VolumeSnapshot. One is from the backup content, and one is dynamically generated from the restore's VolumeSnapshot.
+
+The design aims to clean the unnecessary artifacts, and make the CSI B/R workflow more concise and reliable.
+
+## Goals
+- Clean the redundant VSC generated during CSI backup and restore.
+- Remove the VSCs in the backup sync process.
+
+## Non Goals
+- There were some discussion about whether Velero backup should include VSs and VSCs not generated in during the backup. By far, the conclusion is not including them is a better option. Although that is a useful enhancement, that is not included this design.
+- Delete all the CSI-related metadata files in the BSL is not the aim of this design. 
+
+## Detailed Design
+### Backup
+During backup, the main change is the backup-generated VSCs should not kept anymore.
+
+The reasons is we don't need them to ensure the snapshots clean up during backup deletion. Please reference to the [Backup Deletion section](#backup-deletion) section for detail.
+
+As a result, we can simplify the VS deletion logic in the backup. Before, we need to not only delete the VS, but also recreate a static VSC pointing a non-exiting VS.
+
+The deletion code in VS BackupItemAction can be simplify to the following:
+
+``` go
+	if backup.Status.Phase == velerov1api.BackupPhaseFinalizing ||
+		backup.Status.Phase == velerov1api.BackupPhaseFinalizingPartiallyFailed {
+		p.log.
+			WithField("Backup", fmt.Sprintf("%s/%s", backup.Namespace, backup.Name)).
+			WithField("BackupPhase", backup.Status.Phase).Debugf("Cleaning VolumeSnapshots.")
+
+		if vsc == nil {
+			vsc = &snapshotv1api.VolumeSnapshotContent{}
+		}
+
+		csi.DeleteReadyVolumeSnapshot(*vs, *vsc, p.crClient, p.log)
+		return item, nil, "", nil, nil
+	}
+
+
+func DeleteReadyVolumeSnapshot(
+	vs snapshotv1api.VolumeSnapshot,
+	vsc snapshotv1api.VolumeSnapshotContent,
+	client crclient.Client,
+	logger logrus.FieldLogger,
+) {
+	logger.Infof("Deleting Volumesnapshot %s/%s", vs.Namespace, vs.Name)
+	if vs.Status == nil ||
+		vs.Status.BoundVolumeSnapshotContentName == nil ||
+		len(*vs.Status.BoundVolumeSnapshotContentName) <= 0 {
+		logger.Errorf("VolumeSnapshot %s/%s is not ready. This is not expected.",
+			vs.Namespace, vs.Name)
+		return
+	}
+
+	if vs.Status != nil && vs.Status.BoundVolumeSnapshotContentName != nil {
+		// Patch the DeletionPolicy of the VolumeSnapshotContent to set it to Retain.
+		// This ensures that the volume snapshot in the storage provider is kept.
+		if err := SetVolumeSnapshotContentDeletionPolicy(
+			vsc.Name,
+			client,
+			snapshotv1api.VolumeSnapshotContentRetain,
+		); err != nil {
+			logger.Warnf("Failed to patch DeletionPolicy of volume snapshot %s/%s",
+				vs.Namespace, vs.Name)
+			return
+		}
+
+		if err := client.Delete(context.TODO(), &vsc); err != nil {
+			logger.Warnf("Failed to delete the VSC %s: %s", vsc.Name, err.Error())
+		}
+	}
+	if err := client.Delete(context.TODO(), &vs); err != nil {
+		logger.Warnf("Failed to delete volumesnapshot %s/%s: %v", vs.Namespace, vs.Name, err)
+	} else {
+		logger.Infof("Deleted volumesnapshot with volumesnapshotContent %s/%s",
+			vs.Namespace, vs.Name)
+	}
+}
+```
+
+### Restore
+
+#### Restore the VolumeSnapshotContent
+The current behavior of VSC restoration is that the VSC from the backup is restore, and the restored VS also triggers creating a new VSC dynamically.
+
+Two VSCs created for the same VS in one restore seems not right.
+
+Skip restore the VSC from the backup is not a viable alternative, because VSC may reference to a [snapshot create secret](https://kubernetes-csi.github.io/docs/secrets-and-credentials-volume-snapshot-class.html?highlight=snapshotter-secret-name#createdelete-volumesnapshot-secret).
+
+If the `SkipRestore` is set true in the restore action's result, the secret returned in the additional items is ignored too.
+
+As a result, restore the VSC from the backup, and setup the VSC and the VS's relation is a better choice.
+
+Another consideration is the VSC name should not be the same as the backed-up VSC's, because the older version Velero's restore and backup keep the VSC after completion.
+
+There's high possibility that the restore will fail due to the VSC already exists in the cluster.
+
+Multiple restores of the same backup will also meet the same problem.
+
+The proposed solution is using the restore's UID and the VS's name to generate sha256 hash value as the new VSC name. Both the VS and VSC RestoreItemAction can access those UIDs, and it will avoid the conflicts issues.
+
+The restored VS name also shares the same generated name.
+
+The VS-referenced VSC name and the VSC's snapshot handle name are in their status.
+
+Velero restore process purges the restore resources' metadata and status before running the RestoreItemActions.
+
+As a result, we cannot read these information in the VS and VSC RestoreItemActions.
+
+Fortunately, RestoreItemAction input parameters includes the `ItemFromBackup`. The status is intact in `ItemFromBackup`.
+
+``` go
+func (p *volumeSnapshotRestoreItemAction) Execute(
+	input *velero.RestoreItemActionExecuteInput,
+) (*velero.RestoreItemActionExecuteOutput, error) {
+	p.log.Info("Starting VolumeSnapshotRestoreItemAction")

+	if boolptr.IsSetToFalse(input.Restore.Spec.RestorePVs) {

+	}

+	// the dynamic VolumeSnapshotContent to the static one.
+	resetVolumeSnapshotSpecForRestore(&vs, &newVSCName)

+```
+
+
+### Backup Sync
+csi-volumesnapshotclasses.json, csi-volumesnapshotcontents.json, and csi-volumesnapshots.json are CSI-related metadata files in the BSL for each backup.
+
+csi-volumesnapshotcontents.json and csi-volumesnapshots.json are not needed anymore, but csi-volumesnapshotclasses.json is still needed.
+
+One concrete scenario is that a backup is created in cluster-A, then the backup is synced to cluster-B, and the backup is deleted in the cluster-B. In this case, we don't have a chance to create the VS and VSC needed VolumeSnapshotClass.
+
+The VSC deletion workflow proposed by this design needs to create the VSC first. If the VSC's referenced VolumeSnapshotClass doesn't exist in cluster, the creation of VSC will fail.
+
+As a result, the VolumeSnapshotClass should still be synced in the backup sync process.
+
+### Backup Deletion
+Two factors are worthy for consideration for the backup deletion change:
+* Because the VSCs generated by the backup are not synced anymore, and the VSCs generated during the backup will not be kept too. The backup deletion needs to generate a VSC, then deletes it to make sure the snapshots in the storage provider are clean too.
+* The VSs generated by the backup are already deleted in the backup process, we don't need a DeleteItemAction for the VS anymore. As a result, the `velero.io/csi-volumesnapshot-delete` plugin is unneeded.
+
+For the VSC DeleteItemAction, we need to generate a VSC. Because we only care about the snapshot deletion, we don't need to create a VS associated with the VSC.
+
+Create a static VSC, then point it to a pseudo VS, and reference to the snapshot handle should be enough.
+
+To avoid the created VSC conflict with older version Velero B/R generated ones, the VSC name is set to `vsc-uuid`.
+
+The following is an example of the implementation.
+``` go
+	uuid, err := uuid.NewRandom()
+	if err != nil {
+		p.log.WithError(err).Errorf("Fail to generate the UUID to create VSC %s", snapCont.Name)
+		return errors.Wrapf(err, "Fail to generate the UUID to create VSC %s", snapCont.Name)
+	}
+	snapCont.Name = "vsc-" + uuid.String()
+
+	snapCont.Spec.DeletionPolicy = snapshotv1api.VolumeSnapshotContentDelete
+
+	snapCont.Spec.Source = snapshotv1api.VolumeSnapshotContentSource{
+		SnapshotHandle: snapCont.Status.SnapshotHandle,
+	}
+
+	snapCont.Spec.VolumeSnapshotRef = corev1api.ObjectReference{
+		APIVersion: snapshotv1api.SchemeGroupVersion.String(),
+		Kind:       "VolumeSnapshot",
+		Namespace:  "ns-" + string(snapCont.UID),
+		Name:       "name-" + string(snapCont.UID),
+	}
+
+	snapCont.ResourceVersion = ""
+
+	if err := p.crClient.Create(context.TODO(), &snapCont); err != nil {
+		return errors.Wrapf(err, "fail to create VolumeSnapshotContent %s", snapCont.Name)
+	}
+
+	// Read resource timeout from backup annotation, if not set, use default value.
+	timeout, err := time.ParseDuration(
+		input.Backup.Annotations[velerov1api.ResourceTimeoutAnnotation])
+	if err != nil {
+		p.log.Warnf("fail to parse resource timeout annotation %s: %s",
+			input.Backup.Annotations[velerov1api.ResourceTimeoutAnnotation], err.Error())
+		timeout = 10 * time.Minute
+	}
+	p.log.Debugf("resource timeout is set to %s", timeout.String())
+
+	interval := 5 * time.Second
+
+	// Wait until VSC created and ReadyToUse is true.
+	if err := wait.PollUntilContextTimeout(
+		context.Background(),
+		interval,
+		timeout,
+		true,
+		func(ctx context.Context) (bool, error) {
+			tmpVSC := new(snapshotv1api.VolumeSnapshotContent)
+			if err := p.crClient.Get(ctx, crclient.ObjectKeyFromObject(&snapCont), tmpVSC); err != nil {
+				return false, errors.Wrapf(
+					err, "failed to get VolumeSnapshotContent %s", snapCont.Name,
+				)
+			}
+
+			if tmpVSC.Status != nil && boolptr.IsSetToTrue(tmpVSC.Status.ReadyToUse) {
+				return true, nil
+			}
+
+			return false, nil
+		},
+	); err != nil {
+		return errors.Wrapf(err, "fail to wait VolumeSnapshotContent %s becomes ready.", snapCont.Name)
+	}
+```
+
+## Security Considerations
+Security is not relevant to this design.
+
+## Compatibility
+In this design, no new information is added in backup and restore. As a result, this design doesn't have any compatibility issue.
+
+## Open Issues
+Please notice the CSI snapshot backup and restore mechanism not supporting all file-store-based volume, e.g. Azure Files, EFS or vSphere CNS File Volume. Only block-based volumes are supported.
+Refer to [this comment](https://github.com/vmware-tanzu/velero/issues/3151#issuecomment-2623507686) for more details.

+# Concurrent Backup Processing
+
+This enhancement will enable Velero to process multiple backups at the same time. This is largely a usability enhancement rather than a performance enhancement, since the overall backup throughput may not be significantly improved over the current implementation, since we are already processing individual backup items in parallel. It is a significant usability improvement, though, as with the current design, a user who submits a small backup may have to wait significantly longer than expected if the backup is submitted immediately after a large backup.
+
+## Background
+
+With the current implementation, only one backup may be `InProgress` at a time. A second backup created will not start processing until the first backup moves on to `WaitingForPluginOperations` or `Finalizing`. This is a usability concern, especially in clusters when multiple users are initiating backups. With this enhancement, we intend to allow multiple backups to be processed concurrently. This will allow backups to start processing immediately, even if a large backup was just submitted by another user. This enhancement will build on top of the prior parallel item processing feature by creating a dedicatede ItemBlock worker pool for each running backup. The pool will be created at the beginning of the backup reconcile, and the input channel will be passed to the Kubernetes backupper just like it is in the current release.
+
+The primary challenge is to make sure that the same workload in multiple backups is not backed up concurrently. If that were to happen, we would risk data corruption, especially around the processing of pod hooks and volume backup. For this first release we will take a conservative, high-level approach to overlap detection. Two backups will not run concurrently if there is any overlap in included namespaces. For example, if a backup that includes `ns1` and `ns2` is running, then a second backup for `ns2` and `ns3` will not be started. If a backup which does not filter namespaces is running (either a whole cluster backup or a non-namespace-limited backup with a label selector) then no other backups will be started, since a backup across all namespaces overlaps with any other backup. Calculating item-level overlap for queued backups is problematic since we don't know which items are included in a backup until backup processing has begun. A future release may add ItemBlock overlap detection, where at the item block worker level, the same item will not be processed by two different workers at the same time. This works together with workload conflict detection to further detect conflicts in a more granular level for shared resources between backups. Eventually, with a more complete understanding of individual workloads (either via ItemBlocks or some higher level model), the namespace level overlap detection may be relaxed in future versions.
+
+## Goals
+- Process multiple backups concurrently
+- Detect namespace overlap to avoid conflicts
+- For queued backups (not yet runnable due to concurrency limits or overlap), indicate the queue position in status
+
+## Non Goals
+- Handling NFS PVs when more than one PV point to the same underlying NFS share
+- Handling VGDP cancellation for failed backups on restart
+- Mounting a PVC for scenarios in which /tmp is too small for the number of concurrent backups
+- Providing a mechanism to identify high priority backups which get preferential treatment in terms of ItemBlock worker availability
+- Item-level overlap detection (future feature)
+- Providing the ability to disable namespace-level overlap detection once Item-level overlap detection is in place (although this may be supported in a future version).
+
+## High-Level Design
+
+### Backup CRD changes
+
+Two new backup phases will be added: `Queued` and `ReadyToStart`. In the Backup workflow, new backups will be moved to the Queued phase when they are added to the backup queue. When a backup is removed from the queue because it is now able to run, it will be moved to the `ReadyToStart` phase, which will allow the backup controller to start processing it.
+
+In addition, a new Status field, `QueuePosition`, will be added to track the backup's current position in the queue.
+
+### New Controller: `backupQueueReconciler`
+
+A new reconciler will be added, `backupQueueReconciler` which will use the current `backupReconciler` logic for reconciling `New` backups but instead of running the backup, it will move the Backup to the `Queued` phase and set `QueuePosition`.
+
+In addition, this reconciler will periodically reconcile all queued backups (on some configurable time interval) and if there is a runnable backup, remove it from the queue, update `QueuePosition` for any queued backups behind it, and update its phase to `ReadyToStart`.
+
+Queued backups will be reconciled in order based on `QueuePosition`, so the first runnable backup found will be processed. A backup is runnable if both of the following conditions are true:
+1) The total number of backups either `InProgress` or `ReadyToStart` is less than the configured number of concurrent backups.
+2) The backup has no overlap with any backups currently `InProgress` or `ReadyToStart` or with any `Queued` backups with a higher (i.e. closer to 1) queue position than this backup.
+
+### Updates to Backup controller
+
+The current `backupReconciler` will change its reconciling rules. Instead of watching and reconciling New backups, it will reconcile `ReadyToStart` backups. In addition, it will be configured to run in parallel by setting `MaxConcurrentReconciles` based on the `concurrent-backups` server arg.
+
+The startup (and shutdown) of the ItemBlock worker pool will be moved from reconciler startup to the backup reconcile, which will give each running backup its own dedicated worker pool. The per-backup worker pool will will use the existing `--item-block-worker-count` installer/server arg. This means that the maximum number of ItemBlock workers for the entire Velero pod will be the ItemBlock worker count multiplied by concurrentBackups. For example, if concurrentBackups is 5, and itemBlockWorkerCount is 6, then there will be, at most, 30 worker threads active, 5 dedicated to each InProgress backup, but this maximum will only be achieved when the maximum number of backups are InProgress. This also means that each InProgress backup will have a dedicated ItemBlock input channel with the same fixed buffer size.
+
+## Detailed Design
+
+### New Install/Server configuration args
+
+A new install/server arg, `concurrent-backups` will be added. This will be an int-valued field specifying the number of backups which may be processed concurrently (with phase `InProgress`). If not specified, the default value of 1 will be used.
+
+### Consideration of backup overlap and concurrent backup processing
+
+The primary consideration for running additional backups concurrently is the configured `concurrent-backups` parameter. If the total number of `InProgress` and `ReadyToStart` backups is equal to `concurrent-backups` then any `Queued` backups will remain in the queue.
+
+The second consideration is backup overlap. In order to prevent interaction between running backups (particularly around volume backup and pod hooks), we cannot allow two overlapping backups to run at the same time. For now, we will define overlap broadly -- requiring that two concurrent backups don't include any of the same namespaces. A backup for `ns1` can run concurrently with a backup for `ns2`, but a backup for `[ns1,ns2]` cannot run concurrently with a backup for `ns1`. One consequence of this approach is that a backup which includes all namespaces (even if further filtered by resource or label) cannot run concurrently with *any other backup*.
+
+When determining which queued backup to run next, velero will look for the next queued backup which has no overlap with any InProgress backup or any Queued backup ahead of it. The reason we need to consider queued as well as running backups for overlap detection is as follows.
+
+Consider the following scenario. These are the current not-completed backups (ordered from oldest to newest)
+1. backup1, includedNamespaces: [ns1, ns2], phase: InProgress
+2. backup2, includedNamespaces: [ns2, ns3, ns5], phase: Queued, QueuePosition: 1
+3. backup3, includedNamespaces: [ns4, ns3], phase: Queued, QueuePosition: 2
+4. backup4, includedNamespaces: [ns5, ns6], phase: Queued, QueuePosition: 2
+5. backup5, includedNamespaces: [ns8, ns9], phase: Queued, QueuePosition: 3
+
+Assuming `concurrent-backups` is 2, on the next reconcile, Velero will be able to start a second backup if there is one with no overlap. `backup2` cannot run, since `ns2` overlaps between it and the running `backup1`. If we only considered running overlap (and not queued overlap), then `backup3` could run now. It conflicts with the queued `backup2` on `ns3` but it does not conflict with the running backup. However, if it runs now, then when `backup1` completes, then `backup2` still can't run (since it now overlaps with running `backup3`on `ns3`), so `backup4` starts instead. Now when `backup3` completes, `backup2` still can't run (since it now conflicts with `backup4` on `ns5`). This means that even though it was the second backup created, it's the fourth to run -- providing worse time to completion than without parallel backups. If a queued backup has a large number of namespaces (a full-cluster backup for example), it would never run as long as new single-namespace backups keep being added to the queue.
+
+To resolve this problem we consider both running backups as well as backups ahead in the queue when resolving overlap conflicts. In the above scenario, `backup2` can't run yet since it overlaps with the running backup on `ns2`. In addition, `backup3` and `backup4` also can't run yet since they overlap with queued `backup2`. Therefore, `backup5` will run now. Once `backup1` completes, `backup2` will be free to run.
+
+### Backup CRD changes
+
+New Backup phases:
+```go
+const (
+	// BackupPhaseQueued means the backup has been added to the
+	// queue by the BackupQueueReconciler.
+	BackupPhaseQueued BackupPhase = "Queued"
+
+	// BackupPhaseReadyToStart means the backup has been removed from the
+	// queue by the BackupQueueReconciler and is ready to start.
+	BackupPhaseReadyToStart BackupPhase = "ReadyToStart"
+)
+```
+
+In addition, a new Status field, `queuePosition`, will be added to track the backup's current position in the queue.
+```go
+	// QueuePosition is the position held by the backup in the queue.
+	// QueuePosition=1 means this backup is the next to be considered.
+	// Only relevant when Phase is "Queued"
+	// +optional
+	QueuePosition int `json:"queuePosition,omitempty"`
+```
+
+### New Controller: `backupQueueReconciler`
+
+A new reconciler will be added, `backupQueueReconciler` which will reconcile backups under these conditions:
+1) Watching Create/Update for backups in `New` (or empty) phase
+2) Watching for Backup phase transition from `InProgress` to something else to reconcile all `Queued` backups
+2) Watching for Backup phase transition from `New` (or empty) to `Queued` to reconcile all `Queued` backups
+2) Periodic reconcile of `Queued` backups to handle backups queued at server startup as well as to make sure we never have a situation where backups are queued indefinitely because of a race condition or was otherwise missed in the reconcile on prior backup completion.
+
+The reconciler will be set up as follows -- note that New backups are reconciled on Create/Update, while Queued backups are reconciled when an InProgress backup moves on to another state or when a new backup moves to the Queued state. We also reconcile Queued backups periodically to handle the case of a Velero pod restart with Queued backups, as well as to handle possible edge cases where a queued backup doesn't get moved out of the queue at the point of backup completion or an error occurs during a prior Queued backup reconcile.
+
+```go
+func (c *backupOperationsReconciler) SetupWithManager(mgr ctrl.Manager) error {
+        // only consider Queued backups, order by QueuePosition
+	gp := kube.NewGenericEventPredicate(func(object client.Object) bool {

+```
+
+New backups will be queued: Phase will be set to `Queued`, and `QueuePosition` will be set to a int value incremented from the highest current `QueuePosition` value among Queued backups.
+
+Queued backups will be removed from the queue if runnable:
+1) If the total number of backups either InProgress or ReadyToStart is greater than or equal to the concurrency limit, then exit without removing from the queue.
+2) If the current backup overlaps with any InProgress, ReadyToStart, or Queued backup with `QueuePosition < currentBackup.QueuePosition` then exit without removing from the queue.
+3) If we get here, the backup is runnable. To resolve a potential race condition where an InProgress backup completes between reconciling the backup with QueuePosition `n-1` and reconciling the current backup with QueuePosition `n`, we also check to see whether there are any runnable backups in the queue ahead of this one. The only time this will happen is if a backup completes immediately before reconcile starts which either frees up a concurrency slot or removes a namespace conflict. In this case, we don't want to run the current backup since the one ahead of this one in the queue (which was recently passed over before the InProgress backup completed) must run first. In this case, exit without removing from the queue.
+4) If we get here, remove the backup from the queue by setting Phase to `ReadyToStart` and `QueuePosition` to zero. Decrement the `QueuePosition` of any other Queued backups with a `QueuePosition` higher than the current backup's queue position prior to dequeuing. At this point, the backup reconciler will start the backup.
+
+`if len(inProgressBackups)+len(pendingStartBackups) >= concurrentBackups`
+
+```
+	switch original.Status.Phase {
+	case "", velerov1api.BackupPhaseNew:
+		// enqueue backup -- set phase=Queued, set queuePosition=maxCurrentQueuePosition+1
+	}
+	// We should only ever get these events when added in order by the periodical enqueue source
+	// so as long as the current backup has not conflicts ahead of it or running, we should be good to
+	// dequeue
+	case "", velerov1api.BackupPhaseQueued:
+		// list backups, filter on Queued, ReadyToStart, and InProgress
+		// if number of InProgress backups + number of ReadyToStart backups >= concurrency limit, exit
+		// generate list of all namespaces included in InProgress, ReadyToStart, and Queued backups with
+		// queuePosition < backup.Status.QueuePosition
+		// if overlap found, exit
+		// check backups ahead of this one in the queue for runnability. If any are runnable, exit
+		// dequeue backup: set Phase to ReadyToStart, QueuePosition to 0, and decrement QueuePosition
+		// for all QueuedBackups behind this one in the queue
+	}
+
+```
+
+The queue controller will run as a single reconciler thread, so we will not need to deal with concurrency issues when moving backups from New to Queued or from Queued to ReadyToStart, and all of the updates to QueuePosition will be from a single thread.
+
+### Updates to Backup controller
+
+The Reconcile logic will be updated to respond to ReadyToStart backups instead of New backups:

+
+### Resilience to restart of velero pod
+
+The new backup phases (`Queued` and `ReadyToStart`) will be resilient to velero pod restarts. If the velero pod crashes or is restarted, only backups in the `InProgress` phase will be failed, so there is no change to current behavior. Queued backups will retain their queue position on restart, and ReadyToStart backups will move to InProgress when reconciled.
+
+### Observability
+
+#### Logging
+
+When a backup is dequeued, an info log message will also include the wait time, calculated as `now - creationTimestamp`. When a backup is passed over due to overlap, an info log message will indicate which namespaces were in conflict.
+
+#### Velero CLI
+
+The `velero backup describe` output will include the current queue position for queued backups.

+# Proposal to add include exclude policy to resource policy
+
+This enhancement will allow the user to set include and exclude filters for resources in a resource policy configmap, so that
+these filters are reusable and the user will not need to set them each time they create a backup.
+
+## Background
+As mentioned in issue [#8610](https://github.com/vmware-tanzu/velero/issues/8610).  When there's a long list of resources 
+to include or exclude in a backup, it can be cumbersome to set them each time a backup is created.  There's a requirement to
+set these filters in a separate data structure so that they can be reused in multiple backups.
+
+## High-Level Design
+We may extend the data structure of resource policy to add `includeExcludePolicy`, which include the include and exclude filters 
+in the BackupSpec.  When the user creates a backup which references the resource policy config `velero backup create --resource-policies-configmap <configmap-name>`,
+the filters in "includeExcludePolicy" will take effect to filter the resources when velero collects the resources to backup.
+
+## Detailed Design
+
+### Data Structure
+The map `includeExcludePolicy` contains four fields `includedClusterScopedResources`, `excludedClusterScopedResources`, 
+`includedNamespaceScopedResources`,`excludedNamespaceScopedResources`.  These filters work exactly as the filters defined BackupSpec with
+the same names.  An example of the policy looks like:
+```yaml
+#omitted other irrelevant fields like 'version', 'volumePolicies'
+includeExcludePolicy:
+  includedClusterScopedResources:
+    - "cr"
+    - "crd"
+    - "pv"
+  excludedClusterScopedResources:
+    - "volumegroupsnapshotclass"
+    - "ingressclass"
+  includedNamespaceScopedResources:
+    - "pod"
+    - "service"
+    - "deployment"
+    - "pvc"
+  excludedNamespaceScopedResources:
+    - "configmap"
+```
+These filters are in the form of scoped include/exclude filters, which by design will not work with the "old" resource filters.
+Therefore, when a Backup references a resource policy configmap which has `includeExcludePolicy`, and at the same time it has 
+the "old" resource filters, i.e. `includedResources`, `excludedResources`, `includeClusterResources` set in the BackupSpec, the
+Backup will fail with a validation error.
+
+### Priorities 
+A user may set the include/exclude filters in Backupspec and also in the resource policy configmap.  In this case, the filters 
+in both the Backupspec and the resource policy configmap will take effect.  When there's a conflict, the filters in the Backupspec 
+will take precedence.  For example, if resource X is in the list of `includedNamespaceScopedResources` filter in the Backupspec, but 
+it's also in the list of `excludedClusterScopedResources` in the resource policy configmap, then resource X will be included in the backup.
+In this way, users can set the filters in the resource policy configmap to cover most of their use cases, and then override them 
+in the Backupspec when needed.
+
+### Implementation
+In addition to the data structure change, we will need to implement the following changes:
+1. A new function `CombineWithPolicy` will be added to the struct `ScopeIncludesExcludes`, which will combine the include/exclude filters
+in the resource policy configmap with the include/exclude filters in the Backupspec:  
+```go
+func (ie *ScopeIncludesExcludes) CombineWithPolicy(policy resourcepolicies.IncludeExcludePolicy) {
+	mapFunc := scopeResourceMapFunc(ie.helper)
+	for _, item := range policy.ExcludedNamespaceScopedResources {
+		resolvedItem := mapFunc(item, true)
+		if resolvedItem == "" {
+			continue
+		}
+		if !ie.ShouldInclude(resolvedItem) && !ie.ShouldExclude(resolvedItem) {
+			// The existing includeExcludes in the struct has higher priority, therefore, we should only add the item to the filter
+			// when the struct does not include this item and this item is not yet in the excludes filter.
+			ie.namespaceScopedResourceFilter.excludes.Insert(resolvedItem)
+		}
+		
+	}
+.....
+```
+This function will be called in the `kubernetesBackupper.BackupWithResolvers` function, to make sure the combined `ScopeIncludesExcludes` 
+filter will be assigned to the `ResourceIncludesExcludes` filter of the Backup request.
+
+2. Extra validation code will be added to the function `prepareBackupRequest` of `BackupReconciler` to check if there are "old"
+Resource filters in the BackupSpec when the Backup references a resource policy configmap which has `includeExcludePolicy`.
+
+## Alternatives Considered
+We may put `includeExcludePolicy` in a separate configmap, but it will require adding extra field to BackupSpec to reference the configmap,
+which is not necessary.

+## Abstract
+Velero introduced the concept of Resource Modifiers in v1.12.0. This feature allows the user to specify a configmap with a set of rules to modify the resources during restore. The user can specify the filters to select the resources and then specify the JSON Patch to apply on the resource. This feature is currently limited to the operations supported by JSON Patch RFC.
+This proposal is to add support for JSON Merge Patch and Strategic Merge Patch in the Resource Modifiers. This will allow the user to use the same configmap to apply JSON Merge Patch and Strategic Merge Patch on the resources during restore.
+
+## Goals
+- Allow the user to specify a JSON patch, JSON Merge Patch or Strategic Merge Patch for modification.
+- Allow the user to specify multiple JSON Patch, JSON Merge Patch or Strategic Merge Patch.
+- Allow the user to specify mixed JSON Patch, JSON Merge Patch and Strategic Merge Patch in the same configmap.
+
+## Non Goals
+- Deprecating the existing RestoreItemAction plugins for standard substitutions(like changing the namespace, changing the storage class, etc.)
+
+## User Stories
+
+### Scenario 1
+- Alice has some Pods and part of them have an annotation `{"for": "bar"}`.
+- Alice wishes to restore these Pods to a different cluster without this annotation.
+- Alice can use this feature to remove this annotation during restore.
+
+### Scenario 2
+- Bob has a Pod with several containers and one container with name nginx has an image `repo1/nginx`.
+- Bob wishes to restore this Pod to a different cluster, but new cluster can not access repo1, so he pushes the image to repo2.
+- Bob can use this feature to update the image of container nginx to `repo2/nginx` during restore.
+
+## Detailed Design
+- The design and approach is inspired by kubectl patch command and [this doc](https://kubernetes.io/docs/tasks/manage-kubernetes-objects/update-api-object-kubectl-patch/).
+- New fields `MergePatches` and `StrategicPatches` will be added to the `ResourceModifierRule` struct to support all three patch types.
+- Only one of the three patch types can be specified in a single `ResourceModifierRule`.
+- Add wildcard support for `groupResource` in `conditions` struct.
+- The workflow to create Resource Modifier ConfigMap and reference it in RestoreSpec will remain the same as described in document [Resource Modifiers](https://github.com/vmware-tanzu/velero/blob/main/site/content/docs/main/restore-resource-modifiers.md).
+
+### How to choose the right patch type
+- [JSON Merge Patch](https://datatracker.ietf.org/doc/html/rfc7386) is a naively simple format, with limited usability. Probably it is a good choice if you are building something small, with very simple JSON Schema.
+- [JSON Patch](https://datatracker.ietf.org/doc/html/rfc6902) is a more complex format, but it is applicable to any JSON documents. For a comparison of JSON patch and JSON merge patch, see [JSON Patch and JSON Merge Patch](https://erosb.github.io/post/json-patch-vs-merge-patch/).
+- Strategic Merge Patch is a Kubernetes defined patch type, mainly used to process resources of type list. You can replace/merge a list, add/remove items from a list by key, change the order of items in a list, etc. Strategic merge patch is not supported for custom resources. For more details, see [this doc](https://kubernetes.io/docs/tasks/manage-kubernetes-objects/update-api-object-kubectl-patch/).
+
+### New Field MergePatches
+MergePatches is a list to specify the merge patches to be applied on the resource. The merge patches will be applied in the order specified in the configmap. A subsequent patch is applied in order and if multiple patches are specified for the same path, the last patch will override the previous patches.
+
+Example of MergePatches in ResourceModifierRule
+```yaml
+version: v1
+resourceModifierRules:
+- conditions:
+    groupResource: pods
+    namespaces:
+    - ns1
+  mergePatches:
+  - patchData: |
+      {
+        "metadata": {
+          "annotations": {
+            "foo": null
+          }
+        }
+      }
+```
+- The above configmap will apply the Merge Patch to all the pods in namespace ns1 and remove the annotation `foo` from the pods.
+- Both json and yaml format are supported for the patchData.
+
+### New Field StrategicPatches
+StrategicPatches is a list to specify the strategic merge patches to be applied on the resource. The strategic merge patches will be applied in the order specified in the configmap. A subsequent patch is applied in order and if multiple patches are specified for the same path, the last patch will override the previous patches.
+
+Example of StrategicPatches in ResourceModifierRule
+```yaml
+version: v1
+resourceModifierRules:
+- conditions:
+    groupResource: pods
+    resourceNameRegex: "^my-pod$"
+    namespaces:
+    - ns1
+  strategicPatches:
+  - patchData: |
+      {
+        "spec": {
+          "containers": [
+            {
+              "name": "nginx",
+              "image": "repo2/nginx"
+            }
+          ]
+        }
+      }
+```
+- The above configmap will apply the Strategic Merge Patch to the pod with name my-pod in namespace ns1 and update the image of container nginx to `repo2/nginx`.
+- Both json and yaml format are supported for the patchData.
+
+### Conditional Patches in ALL Patch Types
+Since JSON Merge Patch and Strategic Merge Patch do not support conditional patches, we will use the `test` operation of JSON Patch to support conditional patches in all patch types by adding it to `Conditions` struct in `ResourceModifierRule`.
+
+Example of test in conditions
+```yaml
+version: v1
+resourceModifierRules:
+- conditions:
+    groupResource: persistentvolumeclaims.storage.k8s.io
+    matches:
+    - path: "/spec/storageClassName"
+      value: "premium"
+  mergePatches:
+  - patchData: |
+      {
+        "metadata": {
+          "annotations": {
+            "foo": null
+          }
+        }
+      }
+```
+- The above configmap will apply the Merge Patch to all the PVCs in all namespaces with storageClassName premium and remove the annotation `foo` from the PVCs.
+- You can specify multiple rules in the `matches` list. The patch will be applied only if all the matches are satisfied.
+
+### Wildcard Support for GroupResource
+The user can specify a wildcard for groupResource in the conditions' struct. This will allow the user to apply the patches for all the resources of a particular group or all resources in all groups. For example, `*.apps` will apply to all the resources in the `apps` group, `*` will apply to all the resources in all groups.
+
+### Helper Command to Generate Merge Patch and Strategic Merge Patch
+The patchData of Strategic Merge Patch is sometimes a bit complex for user to write. We can provide a helper command to generate the patchData for Strategic Merge Patch. The command will take the original resource and the modified resource as input and generate the patchData.
+It can also be used in JSON Merge Patch.
+
+Here is a sample code snippet to achieve this:
+```go
+package main
+
+import (
+	"fmt"
+
+	corev1 "k8s.io/api/core/v1"
+	"sigs.k8s.io/controller-runtime/pkg/client"
+)
+
+func main() {
+	pod := &corev1.Pod{
+		Spec: corev1.PodSpec{
+			Containers: []corev1.Container{
+				{
+					Name:  "web",
+					Image: "nginx",
+				},
+			},
+		},
+	}
+	newPod := pod.DeepCopy()
+	patch := client.StrategicMergeFrom(pod)
+	newPod.Spec.Containers[0].Image = "nginx1"
+
+	data, _ := patch.Data(newPod)
+	fmt.Println(string(data))
+	// Output:
+	// {"spec":{"$setElementOrder/containers":[{"name":"web"}],"containers":[{"image":"nginx1","name":"web"}]}}
+}
+```
+
+## Security Considerations
+No security impact.
+
+## Compatibility
+Compatible with current Resource Modifiers.
+
+## Implementation
+- Use "github.com/evanphx/json-patch" to support JSON Merge Patch.
+- Use "k8s.io/apimachinery/pkg/util/strategicpatch" to support Strategic Merge Patch.
+- Use glob to support wildcard for `groupResource` in `conditions` struct.
+- Use `test` operation of JSON Patch to calculate the `matches` in `conditions` struct.
+
+## Future enhancements
+- add a Velero subcommand to generate/validate the patchData for Strategic Merge Patch and JSON Merge Patch.
+- add jq support for more complex conditions or patches, to meet the situations that the current conditions or patches can not handle. like [this issue](https://github.com/vmware-tanzu/velero/issues/6344)

+# Multi-arch Build and Windows Build Support
+
+## Background
+
+At present, Velero images could be built for linux-amd64 and linux-arm64. We need to support other platforms, i.e., windows-amd64.  
+At present, for linux image build, we leverage Buildkit's `--platform` option to create the image manifest list in one build call. However, it is a limited way and doesn't fully support all multi-arch scenarios. Specifically, since the build is done in one call with the same parameters, it is impossbile to build images with different configurations (e.g., Windows build requires a different Dockerfile).   
+At present, Velero by default build images locally, or no image or manifest is pushed to registry. However, docker doesn't support multi-arch build locally. We need to clarify the behavior of local build.    
+
+## Goals
+- Refactor the `make container` process to fully support multi-arch build
+- Add Windows build to the existing build process
+- Clarify the behavior of local build with multi-arch build capabilities
+- Don't change the pattern of the final image tag to be used by users
+
+## Non-Goals
+- There may be some workarounds to make the multi-arch image/manifest fully available locally. These workarounds will not be adopted, so local build always build single-arch images
+
+## Local Build
+
+For local build, two values of `--output` parameter for `docker buildx build` are supported:
+- `docker`: a docker format image is built, but the image is only built for the platform (`<os>/<arch>`) as same as the building env. E.g., when building from linux-amd64 env, a single manifest of linux-amd64 is created regardless how the input parameters are configured.  
+- `tar`: one or more images are built as tarballs according to the input platform (`<os>/<arch>`) parameters. Specifically, one tarball is generated for each platform. The build process is the same with the `Build Separate Manifests` of `Push Build` as detailed below. Merely, the `--output` parameter diffs, as `type=tar;dest=<tarball generated path>`. The tarball is generated to the `_output` folder and named with the platform info, e.g., `_output/velero-main-linux-amd64.tar`.  
+
+## Push Build
+
+For push build, the `--output` parameter for `docker buildx build` is always `registry`. And build will go according to the input parameters and create multi-arch manifest lists.    
+
+### Step 1: Build Separate Manifests
+
+Instead of specifying multiple platforms (`<os>/<arch>`) to `--platform` option, we add multiple `container-%` targets in Makefile and each target builds one platform representively.  
+
+The goal here is to build multiple manifests through the multiple targets. However, `docker buildx build` by default creates a manifest list even though there is only one element in `--platform`. Therefore, two flags `--provenance=false` and `--sbom=false` will be set additionally to force `docker buildx build` to create manifests.  
+
+Each manifest has a unique tag, the OS type and arch is added to the tag, in the pattern `$(REGISTRY)/$(BIN):$(VERSION)-$(OS)-$(ARCH)`. For example, `velero/velero:main-linux-amd64`.  
+
+All the created manifests will be pushed to registry so that the all-in-one manifest list could be created.  
+
+### Step 2: Create All-In-One Manifest List
+
+The next step is to create a manifest list to include all the created manifests. This could be done by `docker manifest create` command, the tags created and pushed at Step 1 are passed to this command.  
+A tag is also created for the manifest list, in the pattern `$(REGISTRY)/$(BIN):$(VERSION)`. For example, `velero/velero:main`.  
+
+### Step 3: Push All-In-One Manifest List
+
+The created manifest will be pushed to registry by command `docker manifest push`.  
+
+## Input Parameters
+
+Below are the input parameters that are configurable to meet different build purposes during Dev and release cycle:
+- BUILD_OUTPUT_TYPE: the type of output for the build, i.e., `docker`, `tar`, `registry`, while `docker` and `tar` is for local build; `registry` means push build. Default value is `docker`  
+- BUILD_OS: which types of OS should be built for. Multiple values are accepted, e.g., `linux,windows`. Default value is `linux`  
+- BUILD_ARCH: which types of architecture should be built for. Multiple values are accepted, e.g., `amd64,arm64`. Default value is `amd64`  
+- BUILDX_INSTANCE: an existing buildx instance to be used by the build. Default value is <empty> which indicates the build to create a new buildx instance  
+
+## Windows Build
+
+Windows container images vary from Windows OS versions, e.g., `ltsc2022` for Windows server 2022 and `1809` for Windows server 2019. Images for different OS versions should be built separately.  
+Therefore, separate build targets are added for each OS version, like `container-windows-%`.  
+For the same reason, a new input parameter is added, `BUILD_WINDOWS_VERSION`. The default value is `ltsc2022`. Windows server 2022 is the only base image we will deliver officially, Windows server 2019 is not supported. In future, we may need to support Windows server 2025 base image.  
+For local build to tar, the Windows OS version is also added to the name of the tarball, e.g., `_output/velero-main-windows-ltsc2022-amd64.tar`.  
+
+At present, Windows container image only supports `amd64` as the architecture, so `BUILD_ARCH` is ignored for Windows.  
+
+The Windows manifests need to be annotated with os type, arch, and os version. This will be done through `docker manifest annotate` command.  
+
+## Use Malti-arch Images
+
+In order to use the images, the manifest list's tag should be provided to `velero install` command or helm, the individual manifests are covered by the manifest list. During launch time, the container engine will load the right image to the container according to the platform of the running node.  
+
+## Build Samples
+
+**Local build to docker**
+```
+make container
+```
+The built image could be listed by `docker image ls`.  
+
+**Local build for linux-amd64 and windows-amd64 to tar**
+```
+BUILD_OUTPUT_TYPE=tar BUILD_OS=linux,windows make container
+```
+Under `_output` directory, below files are generated:  
+```
+velero-main-linux-amd64.tar
+velero-main-windows-ltsc2022-amd64.tar
+``` 
+
+**Local build for linux-amd64, linux-arm64 and windows-amd64 to tar**
+```
+BUILD_OUTPUT_TYPE=tar BUILD_OS=linux,windows BUILD_ARCH=amd64,arm64 make container
+```
+Under `_output` directory, below files are generated:  
+```
+velero-main-linux-amd64.tar
+velero-main-linux-arm64.tar
+velero-main-windows-ltsc2022-amd64.tar
+```
+
+**Push build for linux-amd64 and windows-amd64**  
+Prerequisite: login to registry, e.g., through `docker login`  
+```
+BUILD_OUTPUT_TYPE=registry REGISTRY=<registry> BUILD_OS=linux,windows make container

+# Node-agent Load Affinity Design
+
+## Glossary & Abbreviation
+
+**Velero Generic Data Path (VGDP)**: VGDP is the collective modules that is introduced in [Unified Repository design][1]. Velero uses these modules to finish data transfer for various purposes (i.e., PodVolume backup/restore, Volume Snapshot Data Movement). VGDP modules include uploaders and the backup repository.  
+
+**Exposer**: Exposer is a module that is introduced in [Volume Snapshot Data Movement Design][2]. Velero uses this module to expose the volume snapshots to Velero node-agent pods or node-agent associated pods so as to complete the data movement from the snapshots.    
+
+## Background
+
+Velero node-agent is a daemonset hosting controllers and VGDP modules to complete the concrete work of backups/restores, i.e., PodVolume backup/restore, Volume Snapshot Data Movement backup/restore.  
+Specifically, node-agent runs DataUpload controllers to watch DataUpload CRs for Volume Snapshot Data Movement backups, so there is one controller instance in each node. One controller instance takes a DataUpload CR and then launches a VGDP instance, which initializes a uploader instance and the backup repository connection, to finish the data transfer. The VGDP instance runs inside a node-agent pod or in a pod associated to the node-agent pod in the same node.  
+
+Varying from the data size, data complexity, resource availability, VGDP may take a long time and remarkable resources (CPU, memory, network bandwidth, etc.).  
+Technically, VGDP instances are able to run in any node that allows pod schedule. On the other hand, users may want to constrain the nodes where VGDP instances run for various reasons, below are some examples:  
+- Prevent VGDP instances from running in specific nodes because users have more critical workloads in the nodes  
+- Constrain VGDP instances to run in specific nodes because these nodes have more resources than others  
+- Constrain VGDP instances to run in specific nodes because the storage allows volume/snapshot provisions in these nodes only  
+
+Therefore, in order to improve the compatibility, it is worthy to configure the affinity of VGDP to nodes, especially for backups for which VGDP instances run frequently and centrally.  
+
+## Goals
+
+- Define the behaviors of node affinity of VGDP instances in node-agent for volume snapshot data movement backups  
+- Create a mechanism for users to specify the node affinity of VGDP instances for volume snapshot data movement backups  
+
+## Non-Goals
+- It is also beneficial to support VGDP instances affinity for PodVolume backup/restore, however, it is not possible since VGDP instances for PodVolume backup/restore should always run in the node where the source/target pods are created.  
+- It is also beneficial to support VGDP instances affinity for data movement restores, however, it is not possible in some cases. For example, when the `volumeBindingMode` in the StorageClass is `WaitForFirstConsumer`, the restore volume must be mounted in the node where the target pod is scheduled, so the VGDP instance must run in the same node. On the other hand, considering the fact that restores may not frequently and centrally run, we will not support data movement restores.  
+- As elaborated in the [Volume Snapshot Data Movement Design][2], the Exposer may take different ways to expose snapshots, i.e., through backup pods (this is the only way supported at present). The implementation section below only considers this approach currently, if a new expose method is introduced in future, the definition of the affinity configurations and behaviors should still work, but we may need a new implementation.  
+
+## Solution
+
+We will use the ConfigMap specified by `velero node-agent` CLI's parameter `--node-agent-configmap` to host the node affinity configurations.
+This configMap is not created by Velero, users should create it manually on demand. The configMap should be in the same namespace where Velero is installed. If multiple Velero instances are installed in different namespaces, there should be one configMap in each namespace which applies to node-agent in that namespace only.  
+Node-agent server checks these configurations at startup time and use it to initiate the related VGDP modules. Therefore, users could edit this configMap any time, but in order to make the changes effective, node-agent server needs to be restarted.  
+Inside the ConfigMap we will add one new kind of configuration as the data in the configMap, the name is ```loadAffinity```.  
+Users may want to set different LoadAffinity configurations according to different conditions (i.e., for different storages represented by StorageClass, CSI driver, etc.), so we define ```loadAffinity``` as an array. This is for extensibility consideration, at present, we don't implement multiple configurations support, so if there are multiple configurations, we always take the first one in the array.  
+
+The data structure is as below:
+```go
+type Configs struct {
+	// LoadConcurrency is the config for load concurrency per node.
+	LoadConcurrency *LoadConcurrency `json:"loadConcurrency,omitempty"`
+
+	// LoadAffinity is the config for data path load affinity.
+	LoadAffinity []*LoadAffinity `json:"loadAffinity,omitempty"`    
+}
+
+type LoadAffinity struct {
+    // NodeSelector specifies the label selector to match nodes
+    NodeSelector metav1.LabelSelector `json:"nodeSelector"`
+}
+```
+
+### Affinity
+Affinity configuration means allowing VGDP instances running in the nodes specified. There are two ways to define it:
+-  It could be defined by `MatchLabels` of `metav1.LabelSelector`. The labels defined in `MatchLabels` means a `LabelSelectorOpIn` operation by default, so in the current context, they will be treated as affinity rules.  
+- It could be defined by `MatchExpressions` of `metav1.LabelSelector`. The labels are defined in `Key` and `Values` of `MatchExpressions` and the `Operator` should be defined as `LabelSelectorOpIn` or `LabelSelectorOpExists`. 
+
+### Anti-affinity
+Anti-affinity configuration means preventing VGDP instances running in the nodes specified. Below is the way to define it:  
+- It could be defined by `MatchExpressions` of `metav1.LabelSelector`. The labels are defined in `Key` and `Values` of `MatchExpressions` and the `Operator` should be defined as `LabelSelectorOpNotIn` or `LabelSelectorOpDoesNotExist`.   
+
+### Sample
+A sample of the ConfigMap is as below:
+```json
+{
+    "loadAffinity": [
+        {
+            "nodeSelector": {
+                "matchLabels": {
+                    "beta.kubernetes.io/instance-type": "Standard_B4ms"
+                },
+                "matchExpressions": [
+                    {
+                        "key": "kubernetes.io/hostname",
+                        "values": [
+                            "node-1",
+                            "node-2",
+                            "node-3"
+                        ],
+                        "operator": "In"
+                    },
+                    {
+                        "key": "xxx/critial-workload",
+                        "operator": "DoesNotExist"
+                    }
+                ]          
+            }
+        }
+    ]
+}
+```
+This sample showcases two affinity configurations:
+- matchLabels: VGDP instances will run only in nodes with label key `beta.kubernetes.io/instance-type` and value `Standard_B4ms`
+- matchExpressions: VGDP instances will run in node `node1`, `node2` and `node3` (selected by `kubernetes.io/hostname` label)
+
+This sample showcases one anti-affinity configuration:
+- matchExpressions: VGDP instances will not run in nodes with label key `xxx/critial-workload`
+
+To create the configMap, users need to save something like the above sample to a json file and then run below command:
+```
+kubectl create cm <ConfigMap name> -n velero --from-file=<json file name>
+``` 
+
+### Implementation
+As mentioned in the [Volume Snapshot Data Movement Design][2], the exposer decides where to launch the VGDP instances. At present, for volume snapshot data movement backups, the exposer creates backupPods and the VGDP instances will be initiated in the nodes where backupPods are scheduled. So the loadAffinity will be translated (from `metav1.LabelSelector` to `corev1.Affinity`) and set to the backupPods.  
+
+It is possible that node-agent pods, as a daemonset, don't run in every worker nodes, users could fulfil this by specify `nodeSelector` or `nodeAffinity` to the node-agent daemonset spec. On the other hand, at present, VGDP instances must be assigned to nodes where node-agent pods are running. Therefore, if there is any node selection for node-agent pods, users must consider this into this load affinity configuration, so as to guarantee that VGDP instances are always assigned to nodes where node-agent pods are available. This is done by users, we don't inherit any node selection configuration from node-agent daemonset as we think daemonset scheduler works differently from plain pod scheduler, simply inheriting all the configurations may cause unexpected result of backupPod schedule.    
+Otherwise, if a backupPod are scheduled to a node where node-agent pod is absent, the corresponding DataUpload CR will stay in `Accepted` phase until the prepare timeout (by default 30min).  
+
+At present, as part of the expose operations, the exposer creates a volume, represented by backupPVC, from the snapshot. The backupPVC uses the same storageClass with the source volume. If the `volumeBindingMode` in the storageClass is `Immediate`, the volume is immediately allocated from the underlying storage without waiting for the backupPod. On the other hand, the loadAffinity is set to the backupPod's affinity. If the backupPod is scheduled to a node where the snapshot volume is not accessible, e.g., because of storage topologies, the backupPod won't get into Running state, concequently, the data movement won't complete.  
+Once this problem happens, the backupPod stays in `Pending` phase, and the corresponding DataUpload CR stays in `Accepted` phase until the prepare timeout (by default 30min). Below is an example of the backupPod's status when the problem happens:   
+```
+  status:
+    conditions:
+    - lastProbeTime: null
+      message: '0/2 nodes are available: 1 node(s) didn''t match Pod''s node affinity/selector,
+        1 node(s) had volume node affinity conflict. preemption: 0/2 nodes are available:
+        2 Preemption is not helpful for scheduling..'
+      reason: Unschedulable
+      status: "False"
+      type: PodScheduled
+    phase: Pending
+```    
+
+On the other hand, the backupPod is deleted after the prepare timeout, so there is no way to tell the cause is one of the above problems or others.  
+To help the troubleshooting, we can add some diagnostic mechanism to discover the status of the backupPod and node-agent in the same node before deleting it as a result of the prepare timeout.

+# Node-agent Concurrency Design
+
+## Glossary & Abbreviation
+
+**Velero Generic Data Path (VGDP)**: VGDP is the collective of modules that is introduced in [Unified Repository design][1]. Velero uses these modules to finish data transfer for various purposes (i.e., PodVolume backup/restore, Volume Snapshot Data Movement). VGDP modules include uploaders and the backup repository.  
+
+## Background
+
+Velero node-agent is a daemonset hosting controllers and VGDP modules to complete the concrete work of backups/restores, i.e., PodVolume backup/restore, Volume Snapshot Data Movement backup/restore.  
+For example, node-agent runs DataUpload controllers to watch DataUpload CRs for Volume Snapshot Data Movement backups, so there is one controller instance in each node. One controller instance takes a DataUpload CR and then launches a VGDP instance, which initializes a uploader instance and the backup repository connection, to finish the data transfer. The VGDP instance runs inside the node-agent pod or in a pod associated to the node-agent pod in the same node.  
+
+Varying from the data size, data complexity, resource availability, VGDP may take a long time and remarkable resources (CPU, memory, network bandwidth, etc.).  
+Technically, VGDP instances are able to run in concurrent regardless of the requesters. For example, a VGDP instance for a PodVolume backup could run in parallel with another VGDP instance for a DataUpload. Then the two VGDP instances share the same resources if they are running in the same node.  
+
+Therefore, in order to gain the optimized performance with the limited resources, it is worthy to configure the concurrent number of VGDP per node. When the resources are sufficient in nodes, users can set a large concurrent number, so as to reduce the backup/restore time; otherwise, the concurrency should be reduced, otherwise, the backup/restore may encounter problems, i.e., time lagging, hang or OOM kill.  
+
+## Goals
+
+- Define the behaviors of concurrent VGDP instances in node-agent
+- Create a mechanism for users to specify the concurrent number of VGDP per node
+
+## Non-Goals
+- VGDP instances from different nodes always run in concurrent since in most common cases the resources are isolated. For special cases that some resources are shared across nodes, there is no support at present
+- In practice, restores run in prioritized scenarios, e.g., disaster recovery. However, the current design doesn't consider this difference, a VGDP instance for a restore is blocked if it reaches to the limit of the concurrency, even though the ones block it are for backups. If users do meet some problems here, they should consider to stop the backups first
+- Sometimes, users wants to totally block backups/restores from running in a specific node, this is out of the scope the current design. To archive this, more modules need to be considered (i.e., expoers of data movers), simply blocking the VGDP (e.g., by setting its concurrent number to 0) doesn't work. E.g., for a fs backup, VGDP instance must run in the node the source pod is running in, if we simply block from VGDP instance, the PodVolumeBackup CR is still submitted but never processed.  
+
+## Solution
+
+We introduce a ConfigMap specified by `velero node-agent` CLI's parameter `--node-agent-configmap` for users to specify the node-agent related configurations. This configMap is not created by Velero, users should create it manually on demand. The configMap should be in the same namespace where Velero is installed. If multiple Velero instances are installed in different namespaces, there should be one configMap in each namespace which applies to node-agent in that namespace only.  
+Node-agent server checks these configurations at startup time and use it to initiate the related VGDP modules. Therefore, users could edit this configMap any time, but in order to make the changes effective, node-agent server needs to be restarted.  
+The ConfigMap may be used for other purpose of configuring node-agent in future, at present, there is only one kind of configuration as the data in the configMap, the name is ```loadConcurrency```.  
+
+The data structure is as below:
+```go
+type Configs struct {
+	// LoadConcurrency is the config for load concurrency per node.
+	LoadConcurrency *LoadConcurrency `json:"loadConcurrency,omitempty"`
+}
+
+type LoadConcurrency struct {
+    // GlobalConfig specifies the concurrency number to all nodes for which per-node config is not specified
+    GlobalConfig int `json:"globalConfig,omitempty"`
+
+    // PerNodeConfig specifies the concurrency number to nodes matched by rules
+    PerNodeConfig []RuledConfigs `json:"perNodeConfig,omitempty"`
+}
+
+type RuledConfigs struct {
+    // NodeSelector specifies the label selector to match nodes
+    NodeSelector metav1.LabelSelector `json:"nodeSelector"`
+
+    // Number specifies the number value associated to the matched nodes
+    Number int `json:"number"`
+}
+```
+
+### Global concurrent number
+We allow users to specify a concurrent number that will be applied to all nodes if the per-node number is not specified. This number is set through ```globalConfig```.  
+The number starts from 1 which means there is no concurrency, only one instance of VGDP is allowed. There is no roof limit.    
+If this number is not specified or not valid, a hard-coded default value will be used, the value is set to 1. 
+
+### Per-node concurrent number
+We allow users to specify different concurrent number per node, for example, users can set 3 concurrent instances in Node-1, 2 instances in Node-2 and 1 instance in Node-3. This is for below considerations:
+- The resources may be different among nodes. Then users could specify smaller concurrent number for nodes with less resources while larger number for the ones with more resources
+- Help users to isolate critical environments. Users may run some critical workloads in some specified nodes, since VGDP instances may take large resource consumption, users may want to run less number of instances in the nodes with critical workloads
+
+The range of Per-node concurrent number is the same with Global concurrent number.  
+Per-node concurrent number is preferable to Global concurrent number, so it will overwrite the Global concurrent number for that node.  
+
+Per-node concurrent number is implemented through ```perNodeConfig``` field.  
+
+```perNodeConfig``` is a list of ```RuledConfigs``` each item of which matches one or more nodes by label selectors and specify the concurrent number for the matched nodes. This means, the nodes are identified by labels.  
+
+For example, the ```perNodeConfig`` could have below elements:
+```
+"nodeSelector: kubernetes.io/hostname=node1; number: 3"
+"nodeSelector: beta.kubernetes.io/instance-type=Standard_B4ms; number: 5"
+```
+The first element means the node with host name ```node1``` gets the Per-node concurrent number of 3.  
+The second element means all the nodes with label ```beta.kubernetes.io/instance-type``` of value ```Standard_B4ms``` get the Per-node concurrent number of 5. 
+At least one node is expected to have a label with the specified ```RuledConfigs``` element (rule). If no node is with this label, the Per-node rule makes no effect.  
+If one node falls into more than one rules, e.g., if node1 also has the label ```beta.kubernetes.io/instance-type=Standard_B4ms```, the smallest number (3) will be used.  
+
+### Sample
+A sample of the ConfigMap is as below:
+```json
+{
+    "loadConcurrency": {
+        "globalConfig": 2,
+        "perNodeConfig": [
+            {
+                "nodeSelector": {
+                    "matchLabels": {
+                        "kubernetes.io/hostname": "node1"
+                    }
+                },
+                "number": 3
+            },
+            {
+                "nodeSelector": {
+                    "matchLabels": {
+                        "beta.kubernetes.io/instance-type": "Standard_B4ms"
+                    }
+                },
+                "number": 5
+            }
+        ]
+    }
+}
+```
+To create the configMap, users need to save something like the above sample to a json file and then run below command:
+```
+kubectl create cm <ConfigMap name> -n velero --from-file=<json file name>
+```
+
+### Global data path manager
+As for the code implementation, data path manager is to maintain the total number of the running VGDP instances and ensure the limit is not excceeded. At present, there is one data path manager instance per controller, as a result, the concurrent numbers are calculated separately for each controller. This doesn't help to limit the concurrency among different requesters.  
+Therefore, we need to create one global data path manager instance server-wide, and pass it to different controllers. The instance will be created at node-agent server startup.  
+The concurrent number is required to initiate a data path manager, the number comes from either Per-node concurrent number or Global concurrent number.    
+Below are some prototypes related to data path manager:  
+
+```go
+func NewManager(cocurrentNum int) *Manager
+func (m *Manager) CreateFileSystemBR(jobName string, requestorType string, ctx context.Context, client client.Client, namespace string, callbacks Callbacks, log logrus.FieldLogger) (AsyncBR, error)
+```

+# Node-agent Load Soothing Design
+
+## Glossary & Abbreviation
+
+**Velero Generic Data Path (VGDP)**: VGDP is the collective of modules that is introduced in [Unified Repository design][1]. Velero uses these modules to finish data transfer for various purposes (i.e., PodVolume backup/restore, Volume Snapshot Data Movement). VGDP modules include uploaders and the backup repository.  
+
+## Background
+
+As mentioned in [node-agent Concurrency design][2], [CSI Snapshot Data Movement design][3], [VGDP Micro Service design][4] and [VGDP Micro Service for fs-backup design][5], all data movement activities for CSI snapshot data movement backups/restores and fs-backup respect the `loadConcurrency` settings configured in the `node-agent-configmap`. Once the number of existing loads exceeds the corresponding `loadConcurrency` setting, the loads will be throttled and some loads will be held until VGDP quotas are available.  
+However, this throttling only happens after the data mover pod is started and gets to `running`. As a result, when there are large number of concurrent volume backups, there may be many data mover pods get created but the VGDP instances inside them are actually on hold because of the VGDP throttling.  
+This could cause below problems:
+- In some environments, there is a pod limit in each node of the cluster or a pod limit throughout the cluster, too many of the inactive data mover pods may block other pods from running
+- In some environments, the system disk for each node of the cluster is limited, while pods also occupy system disk space, etc., many of the inactive data mover pods also take unnecessary space from system disk and cause other critical pods evicted
+- For CSI snapshot data movement backup, before creation of the data mover pod, the volume snapshot has also created, this means excessive number of snapshots may also be created and live for longer time since the VGDP won't start until the quota is available. However, in some environments, large number of snapshots is not allowed or may cause degradation of the storage peroformance
+
+On the other hand, the VGDP throttling mentioned in [node-agent Concurrency design][2] is an accurate controlling mechanism, that is, exactly the required number of data mover pods are throttled.  
+
+Therefore, another mechanism is required to soothe the creation of the data mover pods and volume snapshots before the VGDP throttling. It doesn't need to accurately control these creations but should effectively reduce the excessive number of inactive data mover pods and volume snapshots.  
+It is not practical to make an accurate control as it is almost impossible to predict which group of nodes a data mover pod is scheduled to, under the consideration of many complex factors, i.e., selected node, affinity, node OS, etc.  
+
+
+## Goals
+
+- Allow users to configure the expected number of loads pending on waiting for VGDP load concurrency quota
+- Create a soothing mechanism to prevent new loads from starting if the number of existing loads excceds the expected number
+
+## Non-Goals
+- Accurately controlling the loads from initiation is not a goal  
+
+## Solution
+
+We introduce a new field `prepareQueueLength` in `loadConcurrency` of `node-agent-configmap` as the allowed number of loads that are under preparing (expose). Specifically, loads are in this situation after its CR is in `Accepted` and `Prepared` phase. The `prepareQueueLength` should be a positive number, negative numbers will be ignored.  
+Once the value is set, the soothing mechanism takes effect, as the best effort, only the allowed number of CRs go into `Accepted` or `Prepared` phase, others will wait and stay as `New` state; and thereby only the allowed number of data mover pods, volume snapshots are created.  
+Otherwise, node-agent works the same as the legacy behavior, CRs go to `Accepted` or `Prepared` state as soon as the controllers process them and data mover pods and volume snapshots are also created without any constraints.  
+If users want to constrain the excessive number of pending data mover pods and volume snapshots, they could set a value by considering the VGDP load concurrency; otherwise, if they don't see constrains for pods or volume snapshots in their environment, they don't need to use this feature, in parallel preparing could also be beneficial for increasing the concurrency.  
+
+Node-agent server checks this configuration at startup time and use it to initiate the related VGDP modules. Therefore, users could edit this configMap any time, but in order to make the changes effective, node-agent server needs to be restarted.  
+
+The data structure is as below:
+```go
+type LoadConcurrency struct {
+    // GlobalConfig specifies the concurrency number to all nodes for which per-node config is not specified
+    GlobalConfig int `json:"globalConfig,omitempty"`
+
+    // PerNodeConfig specifies the concurrency number to nodes matched by rules
+    PerNodeConfig []RuledConfigs `json:"perNodeConfig,omitempty"`
+
+    // PrepareQueueLength specifies the max number of loads that are under expose
+	PrepareQueueLength int `json:"prepareQueueLength,omitempty"`    
+}
+```
+
+### Sample
+A sample of the ConfigMap is as below:
+```json
+{
+    "loadConcurrency": {
+        "globalConfig": 2,
+        "perNodeConfig": [
+            {
+                "nodeSelector": {
+                    "matchLabels": {
+                        "kubernetes.io/hostname": "node1"
+                    }
+                },
+                "number": 3
+            },
+            {
+                "nodeSelector": {
+                    "matchLabels": {
+                        "beta.kubernetes.io/instance-type": "Standard_B4ms"
+                    }
+                },
+                "number": 5
+            }
+        ],
+        "prepareQueueLength": 2
+    }
+}
+```
+To create the configMap, users need to save something like the above sample to a json file and then run below command:
+```
+kubectl create cm <ConfigMap name> -n velero --from-file=<json file name>
+```
+
+## Detailed Design
+Changes apply to the DataUpload Controller, DataDownload Controller, PodVolumeBackup Controller and PodVolumeRestore Controller, as below:
+1. The soothe happens to data mover CRs (DataUpload, DataDownload, PodVolumeBackup or PodVolumeRestore) that are in `New` state
+2. Before starting processing the CR, the corresponding controller counts the existing CRs under or pending for expose in the cluster, that is a total number of existing DataUpload, DataDownload, PodVolumeBackup and PodVolumeRestore that are in either `Accepted` or `Preparing` state  
+3. If the total number doesn't exceed the allowed number, the controller set the CR's phase to `Accepted`
+4. Once the total number exceeds the allowed number, the controller gives up processing the CR and have it requeued later. The delay for the requeue is 5 seconds
+
+The count happens for all the controllers in all nodes, to prevent the checks drain out the API server, the count happens to controller client caches for those CRs. And the count result is also cached, so that the count only happens whenever necessary. Below shows how it judges the necessity:
+- When one or more CRs' phase change to `Accepted`
+- When one or more CRs' phase change from `Accepted` to one of the terminal phases
+- When one or more CRs' phase change from `Prepared` to one of the terminal phases
+- When one or more CRs' phase change from `Prepared` to `InProgress`
+
+Ideally, 2~3 in the above steps need to be synchornized among controllers in all nodes. However, this synchronization is not implemented, the consideration is as below:    
+1. It is impossible to accurately synchronize the count among controllers in different nodes, because the client cache is not coherrent among nodes.  
+2. It is possible to synchronize the count among controllers in the same node. However, it is too expensive to make this synchronization, because 2~3 are part of the expose workflow, the synchronization impacts the performance and stability of the existing workflow. 
+3. Even without the synchronization, the soothing mechanism still works eventually -- when the controllers see all the discharged loads (expected ones and over-discharged ones), they will stop creating new loads until the quota is available again.  
+4. Step 2~3 that need to be synchronized could complete very quickly.    
+
+This is why we say this mechanism is not an accurate control. Or in another word, it is possible that more loads than the number of `prepareQueueLength` are discharged if controllers make the count and expose in the overlapped time (step 2~3).  
+For example, when multiple controllers of the same type (DataUpload, DataDownload, PodVolumeBackup or PodVolumeRestore) from different nodes make the count:  
+```
+max number of waiting loads = number defined by `prepareQueueLength` + number of nodes in cluster
+```
+As another example, when hybrid loads are running the count concurrently, e.g., mix of data mover backups, data mover restores, pod volume backups or pod volume restores, more loads may be discharged and the number depends on the number of concurrent hybrid loads.  
+In either case, because step 2~3 is short in time, it is less likely to reach the theoretically worset result.

+# PriorityClass Support Design Proposal
+
+## Abstract
+
+This design document outlines the implementation of priority class name support for Velero components, including the Velero server deployment, node agent daemonset, and maintenance jobs. This feature allows users to specify a priority class name for Velero components, which can be used to influence the scheduling and eviction behavior of these components.
+
+## Background
+
+Kubernetes allows users to define priority classes, which can be used to influence the scheduling and eviction behavior of pods. Priority classes are defined as cluster-wide resources, and pods can reference them by name. When a pod is created, the priority admission controller uses the priority class name to populate the priority value for the pod. The scheduler then uses this priority value to determine the order in which pods are scheduled.
+
+Currently, Velero does not provide a way for users to specify a priority class name for its components. This can be problematic in clusters where resource contention is high, as Velero components may be evicted or not scheduled in a timely manner, potentially impacting backup and restore operations.
+
+## Goals
+
+- Add support for specifying priority class names for Velero components
+- Update the Velero CLI to accept priority class name parameters for different components
+- Update the Velero deployment, node agent daemonset, maintenance jobs, and data mover pods to use the specified priority class names
+
+## Non Goals
+
+- Creating or managing priority classes
+- Automatically determining the appropriate priority class for Velero components
+
+## High-Level Design
+
+The implementation will add new fields to the Velero options struct to store the priority class names for the server deployment and node agent daemonset. The Velero CLI will be updated to accept new flags for these components. For data mover pods and maintenance jobs, priority class names will be configured through existing ConfigMap mechanisms (`node-agent-configmap` for data movers and `repo-maintenance-job-configmap` for maintenance jobs). The Velero deployment, node agent daemonset, maintenance jobs, and data mover pods will be updated to use their respective priority class names.
+
+## Detailed Design
+
+### CLI Changes
+
+New flags will be added to the `velero install` command to specify priority class names for different components:
+
+```go
+flags.StringVar(
+    &o.ServerPriorityClassName,
+    "server-priority-class-name",
+    o.ServerPriorityClassName,
+    "Priority class name for the Velero server deployment. Optional.",
+)
+
+flags.StringVar(
+    &o.NodeAgentPriorityClassName,
+    "node-agent-priority-class-name",
+    o.NodeAgentPriorityClassName,
+    "Priority class name for the node agent daemonset. Optional.",
+)
+```
+
+Note: Priority class names for data mover pods and maintenance jobs will be configured through their respective ConfigMaps (`--node-agent-configmap` for data movers and `--repo-maintenance-job-configmap` for maintenance jobs).
+
+### Velero Options Changes
+
+The `VeleroOptions` struct in `pkg/install/resources.go` will be updated to include new fields for priority class names:
+
+```go
+type VeleroOptions struct {
+    // ... existing fields ...
+    ServerPriorityClassName       string
+    NodeAgentPriorityClassName    string
+}
+```
+
+### Deployment Changes
+
+The `podTemplateConfig` struct in `pkg/install/deployment.go` will be updated to include a new field for the priority class name:
+
+```go
+type podTemplateConfig struct {
+    // ... existing fields ...
+    priorityClassName string
+}
+```
+
+A new function, `WithPriorityClassName`, will be added to set this field:
+
+```go
+func WithPriorityClassName(priorityClassName string) podTemplateOption {
+    return func(c *podTemplateConfig) {
+        c.priorityClassName = priorityClassName
+    }
+}
+```
+
+The `Deployment` function will be updated to use the priority class name:
+
+```go
+deployment := &appsv1api.Deployment{
+    // ... existing fields ...
+    Spec: appsv1api.DeploymentSpec{
+        // ... existing fields ...
+        Template: corev1api.PodTemplateSpec{
+            // ... existing fields ...
+            Spec: corev1api.PodSpec{
+                // ... existing fields ...
+                PriorityClassName: c.priorityClassName,
+            },
+        },
+    },
+}
+```
+
+### DaemonSet Changes
+
+The `DaemonSet` function will use the priority class name passed via the podTemplateConfig (from the CLI flag):
+
+```go
+daemonSet := &appsv1api.DaemonSet{
+    // ... existing fields ...
+    Spec: appsv1api.DaemonSetSpec{
+        // ... existing fields ...
+        Template: corev1api.PodTemplateSpec{
+            // ... existing fields ...
+            Spec: corev1api.PodSpec{
+                // ... existing fields ...
+                PriorityClassName: c.priorityClassName,
+            },
+        },
+    },
+}
+```
+
+### Maintenance Job Changes
+
+The `JobConfigs` struct in `pkg/repository/maintenance/maintenance.go` will be updated to include a field for the priority class name:
+
+```go
+type JobConfigs struct {
+    // LoadAffinities is the config for repository maintenance job load affinity.
+    LoadAffinities []*kube.LoadAffinity `json:"loadAffinity,omitempty"`
+
+    // PodResources is the config for the CPU and memory resources setting.
+    PodResources *kube.PodResources `json:"podResources,omitempty"`
+    
+    // PriorityClassName is the priority class name for the maintenance job pod
+    // Note: This is only read from the global configuration, not per-repository
+    PriorityClassName string `json:"priorityClassName,omitempty"`
+}
+```
+
+The `buildJob` function will be updated to use the priority class name from the global job configuration:
+
+```go
+func buildJob(cli client.Client, ctx context.Context, repo *velerov1api.BackupRepository, bslName string, config *JobConfigs,
+    podResources kube.PodResources, logLevel logrus.Level, logFormat *logging.FormatFlag) (*batchv1.Job, error) {
+    // ... existing code ...
+    
+    // Use the priority class name from the global job configuration if available
+    // Note: Priority class is only read from global config, not per-repository
+    priorityClassName := ""
+    if config != nil && config.PriorityClassName != "" {
+        priorityClassName = config.PriorityClassName
+    }
+    
+    // ... existing code ...
+    
+    job := &batchv1.Job{
+        // ... existing fields ...
+        Spec: batchv1.JobSpec{
+            // ... existing fields ...
+            Template: corev1api.PodTemplateSpec{
+                // ... existing fields ...
+                Spec: corev1api.PodSpec{
+                    // ... existing fields ...
+                    PriorityClassName: priorityClassName,
+                },
+            },
+        },
+    }
+    
+    // ... existing code ...
+}
+```
+
+Users will be able to configure the priority class name for all maintenance jobs by creating the repository maintenance job ConfigMap before installation. For example:
+
+```bash
+# Create the ConfigMap before running velero install
+cat <<EOF | kubectl create configmap repo-maintenance-job-config -n velero --from-file=config.json=/dev/stdin
+{
+    "global": {
+        "priorityClassName": "low-priority",
+        "podResources": {
+            "cpuRequest": "100m",
+            "memoryRequest": "128Mi"
+        }
+    }
+}
+EOF
+
+# Then install Velero referencing this ConfigMap
+velero install --provider aws \
+    --repo-maintenance-job-configmap repo-maintenance-job-config \
+    # ... other flags
+```
+
+The ConfigMap can be updated after installation to change the priority class for future maintenance jobs. Note that only the "global" configuration is used for priority class - all maintenance jobs will use the same priority class regardless of which repository they are maintaining.
+
+### Node Agent ConfigMap Changes
+
+We'll update the `Configs` struct in `pkg/nodeagent/node_agent.go` to include a field for the priority class name in the node-agent-configmap:
+
+```go
+type Configs struct {
+    // ... existing fields ...
+    
+    // PriorityClassName is the priority class name for the data mover pods 
+    // created by the node agent
+    PriorityClassName string `json:"priorityClassName,omitempty"`
+}
+```
+
+This will allow users to configure the priority class name for data mover pods through the node-agent-configmap. Note that the node agent daemonset itself gets its priority class from the `--node-agent-priority-class-name` CLI flag during installation, not from this configmap. For example:
+
+```bash
+# Create the ConfigMap before running velero install
+cat <<EOF | kubectl create configmap node-agent-config -n velero --from-file=config.json=/dev/stdin
+{
+    "priorityClassName": "low-priority",
+    "loadAffinity": [

+```
+
+The `createBackupPod` function in `pkg/exposer/csi_snapshot.go` will be updated to accept and use the priority class name:
+
+```go
+func (e *csiSnapshotExposer) createBackupPod(
+    ctx context.Context,
+    ownerObject corev1api.ObjectReference,
+    backupPVC *corev1api.PersistentVolumeClaim,
+    operationTimeout time.Duration,
+    label map[string]string,
+    annotation map[string]string,
+    affinity *kube.LoadAffinity,
+    resources corev1api.ResourceRequirements,
+    backupPVCReadOnly bool,
+    spcNoRelabeling bool,
+    nodeOS string,
+    priorityClassName string, // New parameter
+) (*corev1api.Pod, error) {
+    // ... existing code ...
+    
+    pod := &corev1api.Pod{
+        // ... existing fields ...
+        Spec: corev1api.PodSpec{
+            // ... existing fields ...
+            PriorityClassName: priorityClassName,
+            // ... existing fields ...
+        },
+    }
+    
+    // ... existing code ...
+}
+```
+
+The call to `createBackupPod` in the `Expose` method will be updated to pass the priority class name retrieved from the node-agent-configmap:
+
+```go
+priorityClassName, _ := kube.GetDataMoverPriorityClassName(ctx, namespace, kubeClient, configMapName)
+backupPod, err := e.createBackupPod(
+    ctx,
+    ownerObject,
+    backupPVC,
+    csiExposeParam.OperationTimeout,
+    csiExposeParam.HostingPodLabels,
+    csiExposeParam.HostingPodAnnotations,
+    csiExposeParam.Affinity,
+    csiExposeParam.Resources,
+    backupPVCReadOnly,
+    spcNoRelabeling,
+    csiExposeParam.NodeOS,
+    priorityClassName, // Priority class name from node-agent-configmap
+)
+```
+
+A new function, `GetDataMoverPriorityClassName`, will be added to the `pkg/util/kube` package (in the same file as `ValidatePriorityClass`) to retrieve the priority class name for data mover pods:
+
+```go
+// In pkg/util/kube/priority_class.go
+
+// GetDataMoverPriorityClassName retrieves the priority class name for data mover pods from the node-agent-configmap
+func GetDataMoverPriorityClassName(ctx context.Context, namespace string, kubeClient kubernetes.Interface, configName string) (string, error) {
+    // configData is a minimal struct to parse only the priority class name from the ConfigMap
+    type configData struct {
+        PriorityClassName string `json:"priorityClassName,omitempty"`
+    }
+
+    // Get the ConfigMap
+    cm, err := kubeClient.CoreV1().ConfigMaps(namespace).Get(ctx, configName, metav1.GetOptions{})
+    if err != nil {
+        if apierrors.IsNotFound(err) {
+            // ConfigMap not found is not an error, just return empty string
+            return "", nil
+        }
+        return "", errors.Wrapf(err, "error getting node agent config map %s", configName)
+    }
+
+    if cm.Data == nil {
+        // No data in ConfigMap, return empty string
+        return "", nil
+    }
+
+    // Extract the first value from the ConfigMap data
+    jsonString := ""
+    for _, v := range cm.Data {
+        jsonString = v
+        break // Use the first value found
+    }
+
+    if jsonString == "" {
+        // No data to parse, return empty string
+        return "", nil
+    }
+
+    // Parse the JSON to extract priority class name
+    var config configData
+    if err := json.Unmarshal([]byte(jsonString), &config); err != nil {
+        // Invalid JSON is not a critical error for priority class
+        // Just return empty string to use default behavior
+        return "", nil
+    }
+
+    return config.PriorityClassName, nil
+}
+```
+
+This function will get the priority class name from the node-agent-configmap. If it's not found, it will return an empty string.
+
+### Validation and Logging
+
+To improve observability and help with troubleshooting, the implementation will include:
+
+1. **Optional Priority Class Validation**: A helper function to check if a priority class exists in the cluster. This function will be added to the `pkg/util/kube` package alongside other Kubernetes utility functions:
+
+```go
+// In pkg/util/kube/priority_class.go
+
+// ValidatePriorityClass checks if the specified priority class exists in the cluster
+// Returns true if the priority class exists or if priorityClassName is empty
+// Returns false if the priority class doesn't exist or validation fails
+// Logs warnings when the priority class doesn't exist
+func ValidatePriorityClass(ctx context.Context, kubeClient kubernetes.Interface, priorityClassName string, logger logrus.FieldLogger) bool {
+    if priorityClassName == "" {
+        return true
+    }
+    
+    _, err := kubeClient.SchedulingV1().PriorityClasses().Get(ctx, priorityClassName, metav1.GetOptions{})
+    if err != nil {
+        if apierrors.IsNotFound(err) {
+            logger.Warnf("Priority class %q not found in cluster. Pod creation may fail if the priority class doesn't exist when pods are scheduled.", priorityClassName)
+        } else {
+            logger.WithError(err).Warnf("Failed to validate priority class %q", priorityClassName)
+        }
+        return false
+    }
+    logger.Infof("Validated priority class %q exists in cluster", priorityClassName)
+    return true
+}
+```
+
+2. **Debug Logging**: Add debug logs when priority classes are applied:
+
+```go
+// In deployment creation
+if c.priorityClassName != "" {
+    logger.Debugf("Setting priority class %q for Velero server deployment", c.priorityClassName)
+}
+
+// In daemonset creation
+if c.priorityClassName != "" {
+    logger.Debugf("Setting priority class %q for node agent daemonset", c.priorityClassName)
+}
+
+// In maintenance job creation
+if priorityClassName != "" {
+    logger.Debugf("Setting priority class %q for maintenance job %s", priorityClassName, job.Name)
+}
+
+// In data mover pod creation
+if priorityClassName != "" {
+    logger.Debugf("Setting priority class %q for data mover pod %s", priorityClassName, pod.Name)
+}
+```
+
+These validation and logging features will help administrators:
+
+- Identify configuration issues early (validation warnings)
+- Troubleshoot priority class application issues
+- Verify that priority classes are being applied as expected
+
+The `ValidatePriorityClass` function should be called at the following points:
+
+1. **During `velero install`**: Validate the priority classes specified via CLI flags:
+   - After parsing `--server-priority-class-name` flag
+   - After parsing `--node-agent-priority-class-name` flag
+
+2. **When reading from ConfigMaps**: Validate priority classes when loading configurations:
+   - In `GetDataMoverPriorityClassName` when reading from node-agent-configmap
+   - In maintenance job controller when reading from repo-maintenance-job-configmap
+
+3. **During pod/job creation** (optional, for runtime validation):
+   - Before creating data mover pods (PVB/PVR/CSI snapshot data movement)
+   - Before creating maintenance jobs
+
+Example usage:
+
+```go
+// During velero install
+if o.ServerPriorityClassName != "" {
+    _ = kube.ValidatePriorityClass(ctx, kubeClient, o.ServerPriorityClassName, logger.WithField("component", "server"))
+    // For install command, we continue even if validation fails (warnings are logged)
+}
+
+// When reading from ConfigMap in node-agent server
+priorityClassName, err := kube.GetDataMoverPriorityClassName(ctx, namespace, kubeClient, configMapName)
+if err == nil && priorityClassName != "" {
+    // Validate the priority class exists in the cluster
+    if kube.ValidatePriorityClass(ctx, kubeClient, priorityClassName, logger.WithField("component", "data-mover")) {
+        dataMovePriorityClass = priorityClassName
+        logger.WithField("priorityClassName", priorityClassName).Info("Using priority class for data mover pods")
+    } else {
+        logger.WithField("priorityClassName", priorityClassName).Warn("Priority class not found in cluster, data mover pods will use default priority")
+        // Clear the priority class to prevent pod creation failures
+        priorityClassName = ""
+    }
+}
+```
+
+Note: The validation function returns a boolean to allow callers to decide how to handle missing priority classes. For the install command, validation failures are ignored (only warnings are logged) to allow for scenarios where priority classes might be created after Velero installation. For runtime components like the node-agent server, the priority class is cleared if validation fails to prevent pod creation failures.
+
+## Alternatives Considered
+
+1. **Using a single flag for all components**: We could have used a single flag for all components, but this would not allow for different priority classes for different components. Since maintenance jobs and data movers typically require lower priority than the Velero server, separate flags provide more flexibility.
+
+2. **Using a configuration file**: We could have added support for specifying the priority class names in a configuration file. However, this would have required additional changes to the Velero CLI and would have been more complex to implement.
+
+3. **Inheriting priority class from parent components**: We initially considered having maintenance jobs inherit their priority class from the Velero server, and data movers inherit from the node agent. However, this approach doesn't allow for the appropriate prioritization of different components based on their importance and resource requirements.
+
+## Security Considerations
+
+There are no security considerations for this feature.
+
+## Compatibility
+
+This feature is compatible with all Kubernetes versions that support priority classes. The PodPriority feature became stable in Kubernetes 1.14. For more information, see the [Kubernetes documentation on Pod Priority and Preemption](https://kubernetes.io/docs/concepts/scheduling-eviction/pod-priority-preemption/).
+
+## ConfigMap Update Strategy
+
+### Static ConfigMap Reading at Startup
+
+The node-agent server reads and parses the ConfigMap once during initialization and passes configurations (like `podResources`, `loadAffinity`, and `priorityClassName`) directly to controllers as parameters. This approach ensures:
+
+- Single ConfigMap read to minimize API calls
+- Consistent configuration across all controllers
+- Validation of priority classes at startup with fallback behavior
+- No need for complex update mechanisms or watchers
+
+ConfigMap changes require a restart of the node-agent to take effect.
+
+### Implementation Approach
+
+1. **Data Mover Controllers**: Receive priority class as a string parameter from node-agent server at initialization
+2. **Maintenance Job Controller**: Read fresh configuration from repo-maintenance-job-configmap at job creation time
+3. ConfigMap changes require restart of components to take effect
+4. Priority class validation happens at startup with automatic fallback to prevent failures
+
+## Implementation
+
+The implementation will involve the following steps:
+
+1. Add the priority class name fields for server and node agent to the `VeleroOptions` struct
+2. Add the priority class name field to the `podTemplateConfig` struct
+3. Add the `WithPriorityClassName` function for the server deployment and daemonset
+4. Update the `Deployment` function to use the server priority class name
+5. Update the `DaemonSet` function to use the node agent priority class name
+6. Update the `JobConfigs` struct to include `PriorityClassName` field
+7. Update the `buildJob` function in maintenance job to use the priority class name from JobConfigs (global config only)
+8. Update the `Configs` struct in node agent to include `PriorityClassName` field for data mover pods
+9. Update the data mover pod creation to use the priority class name from node-agent-configmap
+10. Update the PodVolumeBackup controller to retrieve and apply priority class name from node-agent-configmap
+11. Update the PodVolumeRestore controller to retrieve and apply priority class name from node-agent-configmap
+12. Add the `GetDataMoverPriorityClassName` utility function to retrieve priority class from configmap
+13. Add the priority class name flags for server and node agent to the `velero install` command
+14. Add unit tests for:
+    - `WithPriorityClassName` function
+    - `GetDataMoverPriorityClassName` function
+    - Priority class application in deployment, daemonset, and job specs
+15. Add integration tests to verify:
+    - Priority class is correctly applied to all component pods
+    - ConfigMap updates are reflected in new pods
+    - Empty/missing priority class names are handled gracefully
+16. Update user documentation to include:
+    - How to configure priority classes for each component
+    - Examples of creating ConfigMaps before installation
+    - Expected priority class hierarchy recommendations
+    - Troubleshooting guide for priority class issues
+17. Update CLI documentation for new flags (`--server-priority-class-name` and `--node-agent-priority-class-name`)
+
+Note: The server deployment and node agent daemonset will have CLI flags for priority class. Data mover pods and maintenance jobs will use their respective ConfigMaps for priority class configuration.
+
+This approach ensures that different Velero components can use different priority class names based on their importance and resource requirements:
+
+1. The Velero server deployment can use a higher priority class to ensure it continues running even under resource pressure.
+2. The node agent daemonset can use a medium priority class.
+3. Maintenance jobs can use a lower priority class since they should not run when resources are limited.
+4. Data mover pods can use a lower priority class since they should not run when resources are limited.
+
+### Implementation Considerations
+
+Priority class names are configured through different mechanisms:
+
+1. **Server Deployment**: Uses the `--server-priority-class-name` CLI flag during installation.
+
+2. **Node Agent DaemonSet**: Uses the `--node-agent-priority-class-name` CLI flag during installation.
+
+3. **Data Mover Pods**: Will use the node-agent-configmap (specified via the `--node-agent-configmap` flag). This ConfigMap controls priority class for all data mover pods (including PVB and PVR) created by the node agent.
+
+4. **Maintenance Jobs**: Will use the repository maintenance job ConfigMap (specified via the `--repo-maintenance-job-configmap` flag). Users should create this ConfigMap before running `velero install` with the desired priority class configuration. The ConfigMap can be updated after installation to change priority classes for future maintenance jobs. While the ConfigMap structure supports per-repository configuration for resources and affinity, priority class is intentionally only read from the global configuration to ensure all maintenance jobs have the same priority.
+
+#### ConfigMap Pre-Creation Guide
+
+For components that use ConfigMaps for priority class configuration, the ConfigMaps must be created before running `velero install`. Here's the recommended workflow:
+
+```bash
+# Step 1: Create priority classes in your cluster (if not already existing)
+kubectl apply -f - <<EOF
+apiVersion: scheduling.k8s.io/v1
+kind: PriorityClass
+metadata:
+  name: velero-critical
+value: 100
+globalDefault: false
+description: "Critical priority for Velero server"
+---
+apiVersion: scheduling.k8s.io/v1
+kind: PriorityClass
+metadata:
+  name: velero-standard
+value: 50
+globalDefault: false
+description: "Standard priority for Velero node agent"
+---
+apiVersion: scheduling.k8s.io/v1
+kind: PriorityClass
+metadata:
+  name: velero-low
+value: 10
+globalDefault: false
+description: "Low priority for Velero data movers and maintenance jobs"
+EOF
+
+# Step 2: Create the namespace
+kubectl create namespace velero
+
+# Step 3: Create ConfigMaps for data movers and maintenance jobs
+kubectl create configmap node-agent-config -n velero --from-file=config.json=/dev/stdin <<EOF
+{
+    "priorityClassName": "velero-low"
+}
+EOF
+
+kubectl create configmap repo-maintenance-job-config -n velero --from-file=config.json=/dev/stdin <<EOF
+{
+    "global": {
+        "priorityClassName": "velero-low"
+    }
+}
+EOF
+
+# Step 4: Install Velero with priority class configuration
+velero install \
+    --provider aws \
+    --server-priority-class-name velero-critical \
+    --node-agent-priority-class-name velero-standard \
+    --node-agent-configmap node-agent-config \
+    --repo-maintenance-job-configmap repo-maintenance-job-config \
+    --use-node-agent
+```
+
+#### Recommended Priority Class Hierarchy
+
+When configuring priority classes for Velero components, consider the following hierarchy based on component criticality:
+
+1. **Velero Server (Highest Priority)**:
+   - Example: `velero-critical` with value 100
+   - Rationale: The server must remain running to coordinate backup/restore operations
+
+2. **Node Agent DaemonSet (Medium Priority)**:
+   - Example: `velero-standard` with value 50
+   - Rationale: Node agents need to be available on nodes but are less critical than the server
+
+3. **Data Mover Pods & Maintenance Jobs (Lower Priority)**:
+   - Example: `velero-low` with value 10
+   - Rationale: These are temporary workloads that can be delayed during resource contention
+
+This hierarchy ensures that core Velero components remain operational even under resource pressure, while allowing less critical workloads to be preempted if necessary.
+
+This approach has several advantages:
+
+- Leverages existing configuration mechanisms, minimizing new CLI flags
+- Provides a single point of configuration for related components (node agent and its pods)
+- Allows dynamic configuration updates without requiring Velero reinstallation
+- Maintains backward compatibility with existing installations
+- Enables administrators to set up priority classes during initial deployment
+- Keeps configuration simple by using the same priority class for all maintenance jobs
+
+The priority class name for data mover pods will be determined by checking the node-agent-configmap. This approach provides a centralized way to configure priority class names for all data mover pods. The same approach will be used for PVB (PodVolumeBackup) and PVR (PodVolumeRestore) pods, which will also retrieve their priority class name from the node-agent-configmap.
+
+For PVB and PVR pods specifically, the implementation follows this approach:
+
+1. **Controller Initialization**: Both PodVolumeBackup and PodVolumeRestore controllers are updated to accept a priority class name as a string parameter. The node-agent server reads the priority class from the node-agent-configmap once at startup:
+
+```go
+// In node-agent server startup (pkg/cmd/cli/nodeagent/server.go)
+dataMovePriorityClass := ""
+if s.config.nodeAgentConfig != "" {
+    ctx, cancel := context.WithTimeout(context.Background(), time.Second*30)
+    defer cancel()
+    priorityClass, err := kube.GetDataMoverPriorityClassName(ctx, s.namespace, s.kubeClient, s.config.nodeAgentConfig)
+    if err != nil {
+        s.logger.WithError(err).Warn("Failed to get priority class name from node-agent-configmap, using empty value")
+    } else if priorityClass != "" {
+        // Validate the priority class exists in the cluster
+        if kube.ValidatePriorityClass(ctx, s.kubeClient, priorityClass, s.logger.WithField("component", "data-mover")) {
+            dataMovePriorityClass = priorityClass
+            s.logger.WithField("priorityClassName", priorityClass).Info("Using priority class for data mover pods")
+        } else {
+            s.logger.WithField("priorityClassName", priorityClass).Warn("Priority class not found in cluster, data mover pods will use default priority")
+        }
+    }
+}
+
+// Pass priority class to controllers
+pvbReconciler := controller.NewPodVolumeBackupReconciler(
+    s.mgr.GetClient(), s.mgr, s.kubeClient, ..., dataMovePriorityClass)
+pvrReconciler := controller.NewPodVolumeRestoreReconciler(
+    s.mgr.GetClient(), s.mgr, s.kubeClient, ..., dataMovePriorityClass)
+```
+
+2. **Controller Structure**: Controllers store the priority class name as a field:
+
+```go
+type PodVolumeBackupReconciler struct {
+    // ... existing fields ...
+    dataMovePriorityClass string
+}
+```
+
+3. **Pod Creation**: The priority class is included in the pod spec when creating data mover pods.
+
+### VGDP Micro-Service Considerations
+
+With the introduction of VGDP micro-services (as described in the VGDP micro-service design), data mover pods are created as dedicated pods for volume snapshot data movement. These pods will also inherit the priority class configuration from the node-agent-configmap. Since VGDP-MS pods (backupPod/restorePod) inherit their configurations from the node-agent, they will automatically use the priority class name specified in the node-agent-configmap.
+
+This ensures that all pods created by Velero for data movement operations (CSI snapshot data movement, PVB, and PVR) use a consistent approach for priority class name configuration through the node-agent-configmap.
+
+### How Exposers Receive Configuration
+
+CSI Snapshot Exposer and Generic Restore Exposer do not directly watch or read ConfigMaps. Instead, they receive configuration through their parent controllers:
+
+1. **Controller Initialization**: Controllers receive the priority class name as a parameter during initialization from the node-agent server.
+
+2. **Configuration Propagation**: During reconciliation of resources:
+   - The controller calls `setupExposeParam()` which includes the `dataMovePriorityClass` value
+   - For CSI operations: `CSISnapshotExposeParam.PriorityClassName` is set
+   - For generic restore: `GenericRestoreExposeParam.PriorityClassName` is set
+   - The controller passes these parameters to the exposer's `Expose()` method
+
+3. **Pod Creation**: The exposer creates pods with the priority class name provided by the controller.
+
+This design keeps exposers stateless and ensures:
+- Exposers remain simple and focused on pod creation
+- All configuration flows through controllers consistently
+- No complex state synchronization between components
+- Configuration changes require component restart to take effect

+# PersistentVolume backup information design
+
+## Abstract
+Create a new metadata file in the backup repository's backup name sub-directory to store the backup-including PVC and PV information. The information includes the way of backing up the PVC and PV data, snapshot information, and status. The needed snapshot status can also be recorded there, but the Velero-Native snapshot plugin doesn't provide a way to get the snapshot size from the API, so it's possible that not all snapshot size information is available.
+
+This new additional metadata file is needed when:
+* Get a summary of the backup's PVC and PV information, including how the data in them is backed up, or whether the data in them is skipped from backup.
+* Find out how the PVC and PV should be restored in the restore process.
+* Retrieve the PV's snapshot information for backup.
+
+## Background
+There is already a [PR](https://github.com/vmware-tanzu/velero/pull/6496) to track the skipped PVC in the backup. This design will depend on it and go further to get a summary of PVC and PV information, then persist into a metadata file in the backup repository.
+
+In the restore process, the Velero server needs to decide how the PV resource should be restored according to how the PV is backed up. The current logic is to check whether it's backed up by Velero-native snapshot, by file-system backup, or having `DeletionPolicy` set as `Delete`.
+
+The checks are made by the backup-generated PVBs or Snapshots. There is no generic way to find this information, and the CSI backup and Snapshot data movement backup are not covered.
+
+Another thing that needs noticing is when describing the backup, there is no generic way to find the PV's snapshot information.
+
+## Goals
+- Create a new metadata file to store backup's PVCs and PVs information and volume data backing up method. The file can be used to let downstream consumers generate a summary.
+- Create a generic way to let the Velero server know how the PV resources are backed up.
+- Create a generic way to let the Velero server find the PV corresponding snapshot information.
+
+## Non Goals
+- Unify how to get snapshot size information for all PV backing-up methods, and all other currently not ready PVs' information.
+
+## High-Level Design
+Create _backup-name_-volumes-info.json metadata file in the backup's repository. This file will be encoded to contain all the PVC and PV information included in the backup. The information covers whether the PV or PVC's data is skipped during backup, how its data is backed up, and the backed-up detail information.
+
+Please notice that the new metadata file includes all skipped volume information. This is used to address [the second phase needs of skipped volumes information](https://github.com/vmware-tanzu/velero/issues/5834#issuecomment-1526624211).
+
+The `restoreItem` function can decode the _backup-name_-volumes-info.json file to determine how to handle the PV resource. 
+
+## Detailed Design
+
+### The VolumeInfo structure
+_backup-name_-volumes-info.json file is a structure that contains an array of structure `VolumeInfo`.
+
+``` golang
+type VolumeInfo struct {
+    PVCName        string    // The PVC's name.
+    PVCNamespace   string    // The PVC's namespace.
+    PVName         string    // The PV name.
+    BackupMethod   string    // The way the volume data is backed up. The valid value includes `VeleroNativeSnapshot`, `PodVolumeBackup` and `CSISnapshot`.
+    SnapshotDataMoved bool   // Whether the volume's snapshot data is moved to specified storage.
+
+    Skipped         boolean   // Whether the Volume is skipped in this backup.
+    SkippedReason   string    // The reason for the volume is skipped in the backup.
+    StartTimestamp  *metav1.Time // Snapshot starts timestamp.
+
+    OperationID     string   // The Async Operation's ID.
+
+    CSISnapshotInfo          CSISnapshotInfo
+    SnapshotDataMovementInfo SnapshotDataMovementInfo
+    NativeSnapshotInfo       VeleroNativeSnapshotInfo
+    PVBInfo                  PodVolumeBackupInfo
+    PVInfo                   PVInfo
+}
+
+// CSISnapshotInfo is used for displaying the CSI snapshot status
+type CSISnapshotInfo struct {
+    SnapshotHandle  string       // It's the storage provider's snapshot ID for CSI.
+    Size            int64        // The snapshot corresponding volume size.
+
+    Driver          string  // The name of the CSI driver.
+    VSCName         string // The name of the VolumeSnapshotContent. 
+}
+
+// SnapshotDataMovementInfo is used for displaying the snapshot data mover status.
+type SnapshotDataMovementInfo struct {

+
+### How the VolumeInfo array is generated.
+The function `persistBackup` has `backup *pkgbackup.Request` in parameters.
+From it, the `VolumeSnapshots`, `PodVolumeBackups`, `CSISnapshots`, `itemOperationsList`, and `SkippedPVTracker` can be read. All of them will be iterated and merged into the `VolumeInfo` array, and then persisted into backup repository in function `persistBackup`.
+
+Please notice that the change happened in async operations are not reflected in the new metadata file. The file only covers the volume changes happen in the Velero server process scope.
+
+A new methods are added to BackupStore to download the VolumeInfo metadata file.
+Uploading the metadata file is covered in the exiting `PutBackup` method.
+
+``` golang
+type BackupStore interface {
+    ...
+    GetVolumeInfos(name string) ([]*VolumeInfo, error)
+    ...
+}
+```
+
+### How the VolumeInfo array is used.
+
+#### Generate the PVC backed-up information summary
+The downstream tools can use this VolumeInfo array to format and display their volume information. This is not in the scope of this feature.
+
+#### Retrieve volume backed-up information for `velero backup describe` command
+The `velero backup describe` can also use this VolumeInfo array structure to display the volume information. The snapshot data mover volume should use this structure at first, then the Velero native snapshot, CSI snapshot, and PodVolumeBackup can also use this structure. The detailed implementation is also not in this feature's scope.
+
+#### Let restore know how to restore the PV
+In the function `restoreItem`, it will determine whether to restore the PV resource by checking it in the Velero native snapshots list, PodVolumeBackup list, and its DeletionPolicy. This logic is still kept. The logic will be used when the new `VolumeInfo` metadata cannot be found to support backward compatibility.
+
+``` golang
+	if groupResource == kuberesource.PersistentVolumes {
+		switch {
+		case hasSnapshot(name, ctx.volumeSnapshots):
+            ...
+        case hasPodVolumeBackup(obj, ctx):
+            ...
+        case hasDeleteReclaimPolicy(obj.Object):
+            ...
+        default:
+            ...
+```
+
+After introducing the VolumeInfo array, the following logic will be added.
+``` golang
+	if groupResource == kuberesource.PersistentVolumes {
+        volumeInfo := GetVolumeInfo(pvName)
+		switch volumeInfo.BackupMethod {
+		case VeleroNativeSnapshot:
+            ...
+        case PodVolumeBackup:
+            ...
+        case CSISnapshot:
+            ...
+        default:
+            // Need to check whether the volume is backed up by the SnapshotDataMover.
+            if volumeInfo.SnapshotDataMovement:
+
+            // Check whether the Velero server should restore the PV depending on the DeletionPolicy setting.
+            if volumeInfo.Skipped:
+```
+
+### How the VolumeInfo metadata file is deleted
+_backup-name_-volumes-info.json file is deleted during backup deletion.
+
+## Alternatives Considered
+The restore process needs more information about how the PVs are backed up to determine whether this PV should be restored. The released branches also need a similar function, but backporting a new feature into previous releases may not be a good idea, so according to [Anshul Ahuja's suggestion](https://github.com/vmware-tanzu/velero/issues/6595#issuecomment-1731081580), adding more cases here to support checking PV backed-up by CSI plugin and CSI snapshot data mover: https://github.com/vmware-tanzu/velero/blob/5ff5073cc3f364bafcfbd26755e2a92af68ba180/pkg/restore/restore.go#L1206-L1324.
+
+## Security Considerations
+There should be no security impact introduced by this design.
+
+## Compatibility
+After this design is implemented, there should be no impact on the existing [skipped PVC summary feature](https://github.com/vmware-tanzu/velero/pull/6496).
+
+To support older version backup, which doesn't have the VolumeInfo metadata file, the old logic, which is checking the Velero native snapshots list, PodVolumeBackup list, and PVC DeletionPolicy, is still kept, and supporting CSI snapshots and snapshot data mover logic will be added too.
+
+## Implementation
+This will be implemented in the Velero v1.13 development cycle.
+
+## Open Issues
+There are no open issues identified by now.

+# Volume information for restore design
+
+## Background
+Velero has different ways to handle data in the volumes during restore.  The users want to have more clarity in terms of how
+the volumes are handled in restore process via either Velero CLI or other downstream product which consumes Velero.
+
+## Goals
+- Create new metadata to store the information of the restored volume, which will have the same life-cycle as the restore CR.
+- Consume the metadata in velero CLI to enable it display more details for volumes in the output of `velero restore describe --details`
+
+## Non Goals
+- Provide finer grained control of the volume restore process. The focus of the design is to enable displaying more details.
+- Persist additional metadata like podvolume, datadownloads etc to the restore folder in backup-location.
+
+## Design
+
+### Structure of the restore volume info
+The restore volume info will be stored in a file named like `${restore_name}-vol-info.json`. The content of the file will
+be a list of volume info objects, each of which will map to a volume that is restored, and will contain the information 
+like name of the restored PV/PVC, restore method and related objects to provide details depending on the way it's restored,
+it will look like this:
+```
+[
+  {
+    "pvcName": "nginx-logs-2",
+    "pvcNamespace": "nginx-app-restore",
+    "pvName": "pvc-e320d75b-a788-41a3-b6ba-267a553efa5e",
+    "restoreMethod": "PodVolumeRestore",
+    "snapshotDataMoved": false,
+    "pvrInfo": {
+      "snapshotHandle": "81973157c3a945a5229285c931b02c68",
+      "uploaderType": "kopia",
+      "volumeName": "nginx-logs",
+      "podName": "nginx-deployment-79b56c644b-mjdhp",
+      "podNamespace": "nginx-app-restore"
+    }
+  },
+  {
+    "pvcName": "nginx-logs-1",
+    "pvcNamespace": "nginx-app-restore",
+    "pvName": "pvc-98c151f4-df47-4980-ba6d-470842f652cc",
+    "restoreMethod": "CSISnapshot",
+    "snapshotDataMoved": false,
+    "csiSnapshotInfo": {
+      "snapshotHandle": "snap-01a3b21a5e9f85528",
+      "size": 2147483648,
+      "driver": "ebs.csi.aws.com",
+      "vscName": "velero-velero-nginx-logs-1-jxmbg-hx9x5"
+    }
+  }
+......  
+]
+```
+Each field will have the same meaning as the corresponding field in the backup volume info.  It will not have the fields 
+that were introduced to help with the backup process, like `pvInfo`, `dataupload` etc.
+
+### How the restore volume info is generated
+Two steps are involved in generating the restore volume info, the first is "collection", which is to gather the information 
+for restoration of the volumes, the second is "generation", which is to iterate through the data collected in the first step
+and generate the volume info list as is described above.
+
+Unlike backup, the CR objects created during the restore process will not be persisted to the backup storage location.  
+Therefore, to gather the information needed to generate volume information, we either need to collect the CRs in the middle
+of the restore process, or retrieve the objects based on the `resouce-list.json` of the restore via API server.
+The information to be collected are:
+- **PV/PVC mapping relationship:** It will be collected via the `restore-resource-list.json`, b/c at the time the json is ready, all
+PVCs and PVs are already created.
+- **Native snapshot information:** It will be collected in the restore workflow when each snapshot is restored.
+- **podvolumerestore CRs:** It will be collected in the restore workflow after each pvr is created.
+- **volumesnapshot CRs for CSI snapshot:** It will be collected in the step of collecting PVC info, by reading the `dataSource`
+field in the spec of the PVC.
+- **datadownload CRs** It will be collected in the phase of collecting PVC info, by querying the API-server to list the datadownload
+CRs labeled with the restore name.
+
+After the collection step, the generation step is relatively straight-forward, as we have all the information needed in 
+the data structures.  
+
+The whole collection and generation steps will be done with the "best-effort" manner, i.e. if there are any failures we 
+will only log the error in restore log, rather than failing the whole restore process, we will not put these errors or warnings
+into the `result.json`, b/c it won't impact the restored resources.
+
+Depending on the number of the restored PVCs the "collection" step may involve many API calls, but it's considered acceptable
+b/c at that time the resources are already created, so the actual RTO is not impacted.  By using the client of controller runtime
+we can make the collection step more efficient by using the cache of the API server.  We may consider to make improvements if 
+we observe performance issues, like using multiple go-routines in the collection.
+
+### Implementation
+Because the restore volume info shares the same data structures with the backup volume info, we will refactor the code in 
+package `internal/volume` to make the sub-components in backup volume info shared by both backup and restore volume info.  
+
+We'll introduce a struct called `RestoreVolumeInfoTracker` which encapsulates the logic of collecting and generating the restore volume info:
+```
+// RestoreVolumeInfoTracker is used to track the volume information during restore.
+// It is used to generate the RestoreVolumeInfo array.
+type RestoreVolumeInfoTracker struct {
+	*sync.Mutex
+	restore *velerov1api.Restore
+	log     logrus.FieldLogger
+	client  kbclient.Client
+	pvPvc   *pvcPvMap
+
+	// map of PV name to the NativeSnapshotInfo from which the PV is restored
+	pvNativeSnapshotMap map[string]NativeSnapshotInfo
+	// map of PV name to the CSISnapshot object from which the PV is restored
+	pvCSISnapshotMap map[string]snapshotv1api.VolumeSnapshot
+	datadownloadList *velerov2alpha1.DataDownloadList
+	pvrs             []*velerov1api.PodVolumeRestore
+}
+```
+The `RestoreVolumeInfoTracker` will be created when the restore request is initialized, and it will be passed to the `restoreContext`
+and carried over the whole restore process.  
+
+The `client` in this struct is to be used to query the resources in the restored namespace, and the current client in restore 
+reconciler only watches the resources in the namespace where velero is installed.  Therefore, we need to introduce the 
+`CrClient` which has the same life-cycle of velero server to the restore reconciler, because this is the client that watches all the 
+resources on the cluster.
+
+In addition to that, we will make small changes in the restore workflow to collect the information needed.  We'll make the 
+changes un-intrusive and make sure not to change the logic of the restore to avoid break change or regression.
+We'll also introduce routine changes in the package `pkg/persistence` to persist the restore volume info to the backup storage location.
+
+Last but not least, the `velero restore describe --details` will be updated to display the volume info in the output.  
+
+## Alternatives Considered
+There used to be suggestion that to provide more details about volume, we can query the `backup-vol-info.json` with the resource 
+identifier in `restore-resource-list.json`.  This will not work when there're resource modifiers involved in the restore process,
+which may change the metadata of PVC/PV.  In addition, we may add more detailed restore-specific information about the volumes that is not available
+in the `backup-vol-info.json`.  Therefore, the `restore-vol-info.json` is a better approach.
+
+## Security Considerations
+There should be no security impact introduced by this design.
+
+## Compatibility
+The restore volume info will be consumed by Velero CLI and downstream products for displaying details.  So the functionality 
+of backup and restore will not be impacted for restores created by older versions of Velero which do not have the restore volume info
+metadata.  The client should properly handle the case when the restore volume info does not exist.
+
+The data structures referenced by volume info is shared between both restore and backup and it's not versioned, so in the future 
+we must make sure there will only be incremental changes to the metadata, such that no break change will be introduced to the client.
