 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.

+
+### 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
+  * Backup/restore of NTFS extended attributes/advanced features are not supported, i.e., Security Descriptors, System/Hidden/ReadOnly attributes, Creation Time, NTFS Streams, etc.

+## 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.  
+
+### Runtime and dependencies
+Golang runtime: 1.24.6  
+kopia: 0.21.1  
+
+### 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

+
+### 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

+#### 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.

+# 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.

+# 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,
+			...
+		},
+		...
+	}
+}
+```

+# 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 {
+        secret := &corev1api.Secret{}
+        key := types.NamespacedName{
+            Name:      bsl.Spec.ObjectStorage.CACertRef.Name,
+            Namespace: namespace,
+        }
+        if err := client.Get(ctx, key, secret); err != nil {
+            return "", errors.Wrap(err, "error getting certificate secret")
+        }
+
+        certData, ok := secret.Data[bsl.Spec.ObjectStorage.CACertRef.Key]
+        if !ok {
+            return "", errors.Errorf("key %s not found in secret",
+                bsl.Spec.ObjectStorage.CACertRef.Key)
+        }
+        return string(certData), nil
+    }
+
+    // Fall back to inline caCert (deprecated)
+    if bsl.Spec.ObjectStorage.CACert != nil {
+        return string(bsl.Spec.ObjectStorage.CACert), nil
+    }
+
+    return "", 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] 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.
