f6367ca396 Use PVC to track the CSI snapshot in restore
This commit fixes #7849.
It will use PVC instead of PV to track CSI snapshots to generate restore
volume info metadata.  So that in the case the PVC is not bound to PV
the metadata can be populated correctly.

* 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why the feature is no longer needed or has become detrimental to Velero, as well as whether and how it has been superseded.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`.
## Updating Governance
All substantive changes in Governance require a supermajority agreement by all maintainers.

### Documentation
https://velero.io/docs/v1.15/
### 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
### Runtime and dependencies
Golang runtime: v1.22.8
kopia: v0.17.0
### Limitations/Known issues
#### Read-only backup PVC may not work on SELinux environments
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.

## v1.16
### Download
https://github.com/vmware-tanzu/velero/releases/tag/v1.16.0
### 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

## 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

# 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 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 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) {
p.log.Infof("Restore %s/%s did not request for PVs to be restored.",
input.Restore.Namespace, input.Restore.Name)
return &velero.RestoreItemActionExecuteOutput{SkipRestore: true}, nil
}
var vs snapshotv1api.VolumeSnapshot

}

sha256Bytes := sha256.Sum256([]byte(restoreUID + "/" + vsUID))
return "vsc-" + hex.EncodeToString(sha256Bytes[:])
}
```

len(additionalItems))
return &velero.RestoreItemActionExecuteOutput{

}, nil
}
```
### 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.

# 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.

# 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

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.

# 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": [
{
"nodeSelector": {
"matchLabels": {
"node-role.kubernetes.io/worker": "true"
}
}
}
]
}
EOF
# Then install Velero referencing this ConfigMap
velero install --provider aws \
--node-agent-configmap node-agent-config \
--use-node-agent \
# ... other flags
```
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

# Repository maintenance job configuration design
## Abstract
Add this design to make the repository maintenance job can read configuration from a dedicate ConfigMap and make the Job's necessary parts configurable, e.g. `PodSpec.Affinity` and `PodSpec.Resources`.
## Background
Repository maintenance is split from the Velero server to a k8s Job in v1.14 by design [repository maintenance job](repository-maintenance.md).
The repository maintenance Job configuration was read from the Velero server CLI parameter, and it inherits the most of Velero server's Deployment's PodSpec to fill un-configured fields.
This design introduces a new way to let the user to customize the repository maintenance behavior instead of inheriting from the Velero server Deployment or reading from `velero server` CLI parameters.
The configurations added in this design including the resource limitations, node selection.
It's possible new configurations are introduced in future releases based on this design.
For the node selection, the repository maintenance Job also inherits from the Velero server deployment before, but the Job may last for a while and cost noneligible resources, especially memory.
The users have the need to choose which k8s node to run the maintenance Job.
This design reuses the data structure introduced by design [Velero Generic Data Path affinity configuration](node-agent-affinity.md) to make the repository maintenance job can choose which node running on.
## Goals
- Unify the repository maintenance Job configuration at one place.
- Let user can choose repository maintenance Job running on which nodes.
## Non Goals
- There was an [issue](https://github.com/vmware-tanzu/velero/issues/7911) to require the whole Job's PodSpec should be configurable. That's not in the scope of this design.
- Please notice this new configuration is dedicated for the repository maintenance. Repository itself configuration is not covered.
## Compatibility
v1.14 uses the `velero server` CLI's parameter to pass the repository maintenance job configuration.
In v1.15, those parameters are still kept, including `--maintenance-job-cpu-request`, `--maintenance-job-mem-request`, `--maintenance-job-cpu-limit`, `--maintenance-job-mem-limit`, and `--keep-latest-maintenance-jobs`.
But the parameters read from the ConfigMap specified by `velero server` CLI parameter `--repo-maintenance-job-configmap` introduced by this design have a higher priority.
If there `--repo-maintenance-job-configmap` is not specified, then the `velero server` parameters are used if provided.
If the `velero server` parameters are not specified too, then the default values are used.
* `--keep-latest-maintenance-jobs` default value is 3.
* `--maintenance-job-cpu-request` default value is 0.
* `--maintenance-job-mem-request` default value is 0.
* `--maintenance-job-cpu-limit` default value is 0.
* `--maintenance-job-mem-limit` default value is 0.
## Deprecation
Propose to deprecate the `velero server` parameters `--maintenance-job-cpu-request`, `--maintenance-job-mem-request`, `--maintenance-job-cpu-limit`, `--maintenance-job-mem-limit`, and `--keep-latest-maintenance-jobs` in release-1.15.
That means those parameters will be deleted in release-1.17.
After deletion, those resources-related parameters are replaced by the ConfigMap specified by `velero server` CLI's parameter `--repo-maintenance-job-configmap`.
`--keep-latest-maintenance-jobs` is deleted from `velero server` CLI. It turns into a non-configurable internal parameter, and its value is 3.
Please check [issue 7923](https://github.com/vmware-tanzu/velero/issues/7923) for more information why deleting this parameter.
## Design
This design introduces a new ConfigMap specified by `velero server` CLI parameter `--repo-maintenance-job-configmap` as the source of the repository maintenance job configuration. The specified ConfigMap is read from the namespace where Velero is installed.
If the ConfigMap doesn't exist, the internal default values are used.
Example of using the parameter `--repo-maintenance-job-configmap`:
```
velero server \
...
--repo-maintenance-job-configmap repo-job-config
...
```
**Notice**
* Velero doesn't own this ConfigMap. If the user wants to customize the repository maintenance job, the user needs to create this ConfigMap.
* Velero reads this ConfigMap content at starting a new repository maintenance job, so the ConfigMap change will not take affect until the next created job.
### Structure
The data structure is as below:
```go
type Configs struct {
// LoadAffinity is the config for data path load affinity.
LoadAffinity []*LoadAffinity `json:"loadAffinity,omitempty"`
// PodResources is the config for the CPU and memory resources setting.
PodResources *kube.PodResources `json:"podResources,omitempty"`
}
type LoadAffinity struct {
// NodeSelector specifies the label selector to match nodes
NodeSelector metav1.LabelSelector `json:"nodeSelector"`
}
type PodResources struct {
CPURequest string `json:"cpuRequest,omitempty"`
MemoryRequest string `json:"memoryRequest,omitempty"`
CPULimit string `json:"cpuLimit,omitempty"`
MemoryLimit string `json:"memoryLimit,omitempty"`
}
```
The ConfigMap content is a map.
If there is a key value as `global` in the map, the key's value is applied to all BackupRepositories maintenance jobs that cannot find their own specific configuration in the ConfigMap.
The other keys in the map is the combination of three elements of a BackupRepository:
* The namespace in which BackupRepository backs up volume data.
* The BackupRepository referenced BackupStorageLocation's name.
* The BackupRepository's type. Possible values are `kopia` and `restic`.
Those three keys can identify a [unique BackupRepository](https://github.com/vmware-tanzu/velero/blob/2fc6300f2239f250b40b0488c35feae59520f2d3/pkg/repository/backup_repo_op.go#L32-L37).
If there is a key match with BackupRepository, the key's value is applied to the BackupRepository's maintenance jobs.
By this way, it's possible to let user configure before the BackupRepository is created.
This is especially convenient for administrator configuring during the Velero installation.
For example, the following BackupRepository's key should be `test-default-kopia`.
``` yaml
- apiVersion: velero.io/v1
kind: BackupRepository
metadata:
generateName: test-default-kopia-
labels:
velero.io/repository-type: kopia
velero.io/storage-location: default
velero.io/volume-namespace: test
name: test-default-kopia-kgt6n
namespace: velero
spec:
backupStorageLocation: default
maintenanceFrequency: 1h0m0s
repositoryType: kopia
resticIdentifier: gs:jxun:/restic/test
volumeNamespace: test
```
The `LoadAffinity` structure is reused from design [Velero Generic Data Path affinity configuration](node-agent-affinity.md).
It's possible that the users want to choose nodes that match condition A or condition B to run the job.
For example, the user want to let the nodes is in a specified machine type or the nodes locate in the us-central1-x zones to run the job.
This can be done by adding multiple entries in the `LoadAffinity` array.
### Affinity Example
A sample of the ConfigMap is as below:
``` bash
cat <<EOF > repo-maintenance-job-config.json
{
"global": {
podResources: {
"cpuRequest": "100m",

This sample showcases two affinity configurations:
- matchLabels: maintenance job runs on nodes with label key `cloud.google.com/machine-family` and value `e2`.
- matchLabels: maintenance job runs on nodes located in `us-central1-a`, `us-central1-b` and `us-central1-c`.
The nodes matching one of the two conditions are selected.
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 repo-maintenance-job-config -n velero --from-file=repo-maintenance-job-config.json
```
### Value assigning rules
If the Velero BackupRepositoryController cannot find the introduced ConfigMap, the following default values are used for repository maintenance job:
``` go
config := Configs {
// LoadAffinity is the config for data path load affinity.
LoadAffinity: nil,
// Resources is the config for the CPU and memory resources setting.
PodResources: &kube.PodResources{
// The repository maintenance job CPU request setting
CPURequest: "0m",
// The repository maintenance job memory request setting
MemoryRequest: "0Mi",
// The repository maintenance job CPU limit setting
CPULimit: "0m",
// The repository maintenance job memory limit setting
MemoryLimit: "0Mi",
},
}
```
If the Velero BackupRepositoryController finds the introduced ConfigMap with only `global` element, the `global` value is used.
If the Velero BackupRepositoryController finds the introduced ConfigMap with only element matches the BackupRepository, the matched element value is used.
If the Velero BackupRepositoryController finds the introduced ConfigMap with both `global` element and element matches the BackupRepository, the matched element defined values overwrite the `global` value, and the `global` value is still used for matched element undefined values.
For example, the ConfigMap content has two elements.
``` json
{
"global": {
"loadAffinity": [
{
"nodeSelector": {
"matchExpressions": [
{
"key": "cloud.google.com/machine-family",
"operator": "In",
"values": [
"e2"
]
}
]
}
},
],
"podResources": {
"cpuRequest": "100m",
"cpuLimit": "200m",
"memoryRequest": "100Mi",
"memoryLimit": "200Mi"
}
},
"ns1-default-kopia": {
"podResources": {
"memoryRequest": "400Mi",
"memoryLimit": "800Mi"
}
}
}
```
The config value used for BackupRepository backing up volume data in namespace `ns1`, referencing BSL `default`, and the type is `Kopia`:
``` go
config := Configs {
// LoadAffinity is the config for data path load affinity.
LoadAffinity: []*kube.LoadAffinity{
{
NodeSelector: metav1.LabelSelector{
MatchExpressions: []metav1.LabelSelectorRequirement{
{
Key: "cloud.google.com/machine-family",
Operator: metav1.LabelSelectorOpIn,
Values: []string{"e2"},
},
},
},
},
},
PodResources: &kube.PodResources{
// The repository maintenance job CPU request setting
CPURequest: "",
// The repository maintenance job memory request setting
MemoryRequest: "400Mi",
// The repository maintenance job CPU limit setting
CPULimit: "",
// The repository maintenance job memory limit setting
MemoryLimit: "800Mi",
}
}
```
### Implementation
During the Velero repository controller starts to maintain a repository, it will call the repository manager's `PruneRepo` function to build the maintenance Job.
The ConfigMap specified by `velero server` CLI parameter `--repo-maintenance-job-configmap` is get to reinitialize the repository `MaintenanceConfig` setting.
``` go
jobConfig, err := getMaintenanceJobConfig(
context.Background(),
m.client,
m.log,
m.namespace,
m.repoMaintenanceJobConfig,
repo,
)
if err != nil {
log.Infof("Cannot find the ConfigMap %s with error: %s. Use default value.",
m.namespace+"/"+m.repoMaintenanceJobConfig,
err.Error(),
)
}
log.Info("Start to maintenance repo")
maintenanceJob, err := m.buildMaintenanceJob(
jobConfig,
param,
)
if err != nil {
return errors.Wrap(err, "error to build maintenance job")
}
```
## Alternatives Considered
An other option is creating each ConfigMap for a BackupRepository.
This is not ideal for scenario that has a lot of BackupRepositories in the cluster.

# Allow Object-Level Resource Status Restore in Velero
## Abstract
This design proposes a way to enhance Veleros restore functionality by enabling object-level resource status restoration through annotations.
Currently, Velero allows restoring resource statuses only at a resource type level, which lacks granularity of restoring the status of specific resources.
By introducing an annotation that controllers can set on individual resource objects, this design aims to improve flexibility and autonomy for users/resource-controllers, providing a more way
to enable resource status restore.
## Background
Velero provides the `restoreStatus` field in the Restore API to specify resource types for status restoration. However, this feature is limited to resource types as a whole, lacking the granularity needed to restore specific objects of a resource type. Resource controllers, especially those managing custom resources with external dependencies, may need to restore status on a per-object basis based on internal logic and dependencies.
This design adds an annotation-based approach to allow controllers to specify status restoration at the object level, enabling Velero to handle status restores more flexibly.
## Goals
- Provide a mechanism to specify the restoration of a resources status at an object level.
- Maintain backwards compatibility with existing functionality, allowing gradual adoption of this feature.
- Integrate the new annotation-based objects-level status restore with Veleros existing resource-type-level `restoreStatus` configuration.
## Non-Goals
- Alter Veleros existing resource type-level status restoration mechanism for resources without annotations.
## Use-Cases/Scenarios
1. Controller managing specific Resources
- A resource controller identifies that a specific object of a resource should have its status restored due to particular dependencies
- The controller automatically sets the `velero.io/restore-status: true` annotation on the resource.
- During restore, Velero restores the status of this object, while leaving other resources unaffected.
- The status for the annotated object will be restored regardless of its inclusion/exclusion in `restoreStatus.includedResources`
2. A specific object must not have its status restored even if its included in `restoreStatus.includedResources`
- A user specifies a resource type in the `restoreStatus.includedResources` field within the Restore custom resource.
- A particular object of that resource type is annotated with `velero.io/restore-status: false` by the user.
- The status of the annotated object will not restored even though its included in `restoreStatus.includedResources` because annotation is `false` and it takes precedence.
4. Default Behavior for objects Without the Annotation
- Objects without the `velero.io/restore-status` annotation behave as they currently do: Velero skips their status restoration unless the resource type is specified in the `restoreStatus.includedResources` field.
## High-Level Design
- Object-Level Status Restore Annotation: We are introducing the `velero.io/restore-status` annotation at the resource object level to mark specific objects for status restoration.
- `true`: Indicates that the status should be restored for this object
- `false`: Skip restoring status for this specific object
- Invalid or missing annotations defer to the meaning of existing resource type-level logic.
- Restore logic precedence:
- Annotations take precedence when they exist with valid values (`true` or `false`).
- Restore spec `restoreStatus.includedResources` is only used when annotations are invalid or missing.
- Velero Restore Logic Update: During a restore operation, Velero will:
- Extend the existing restore logic to parse and prioritize annotations introduced in this design.
- Update resource objects accordingly based on their annotation values or fallback configuration.
## Detailed Design
- Annotation for object-Level Status Restore: The `velero.io/restore-status` annotation will be set on individual resource objects by users/controllers as needed:
```yaml
metadata:
annotations:
velero.io/restore-status: "true"
```
- Restore Logic Modifications: During the restore operation, the restore controller will follow these steps:
- Parse the `restoreStatus.includedResources` spec to determine resource types eligible for status restoration.
- For each resource object:
- Check for the `velero.io/restore-status` annotation.
- If the annotation value is:
- `true`: Restore the status of the object
- `false`: Skip restoring the status of the object
- If the annotation is invalid or missing:
- Default to the `restoreStatus.includedResources` configuration
## Implementation
We are targeting the implementation of this design for Velero 1.16 release.
Current restoreStatus logic resides here: https://github.com/vmware-tanzu/velero/blob/32a8c62920ad96c70f1465252c0197b83d5fa6b6/pkg/restore/restore.go#L1652
The modified logic would look somewhat like:
```go
// Determine whether to restore status from resource type configuration
shouldRestoreStatus := ctx.resourceStatusIncludesExcludes != nil && ctx.resourceStatusIncludesExcludes.ShouldInclude(groupResource.String())
// Check for object-level annotation
annotations := obj.GetAnnotations()
objectAnnotation := annotations["velero.io/restore-status"]
annotationValid := objectAnnotation == "true" || objectAnnotation == "false"
// Determine restore behavior based on annotation precedence
shouldRestoreStatus = (annotationValid && objectAnnotation == "true") || (!annotationValid && shouldRestoreStatus)
ctx.log.Debugf("status field for %s: exists: %v, should restore: %v (by annotation: %v)", newGR, statusFieldExists, shouldRestoreStatus, annotationValid)
if shouldRestoreStatus && statusFieldExists {
if err := unstructured.SetNestedField(obj.Object, objStatus, "status"); err != nil {
ctx.log.Errorf("Could not set status field %s: %v", kube.NamespaceAndName(obj), err)
errs.Add(namespace, err)
return warnings, errs, itemExists
}
obj.SetResourceVersion(createdObj.GetResourceVersion())
updated, err := resourceClient.UpdateStatus(obj, metav1.UpdateOptions{})
if err != nil {
ctx.log.Infof("Status field update failed %s: %v", kube.NamespaceAndName(obj), err)
warnings.Add(namespace, err)
} else {
createdObj = updated
}
}

# Backup Restore Status Patch Retrying Configuration
## Abstract
When a backup/restore completes, we want to ensure that the custom resource progresses to the correct status.
If a patch call fails to update status to completion, it should be retried up to a certain time limit.
This design proposes a way to configure timeout for this retry time limit.
## Background
Original Issue: https://github.com/vmware-tanzu/velero/issues/7207
Velero was performing a restore when the API server was rolling out to a new version.
It had trouble connecting to the API server, but eventually, the restore was successful.
However, since the API server was still in the middle of rolling out, Velero failed to update the restore CR status and gave up.
After the connection was restored, it didn't attempt to update, causing the restore CR to be stuck at "In progress" indefinitely.
This can lead to incorrect decisions for other components that rely on the backup/restore CR status to determine completion.
## Goals
- Make timeout configurable for retry patching by reusing existing [`--resource-timeout` server flag](https://github.com/vmware-tanzu/velero/blob/d9ca14747925630664c9e4f85a682b5fc356806d/pkg/cmd/server/server.go#L245)
## Non Goals
- Create a new timeout flag
- Refactor backup/restore workflow
## High-Level Design
We will add retries with timeout to existing patch calls that moves a backup/restore from InProgress to a different status phase such as
- FailedValidation (final)
- Failed (final)
- WaitingForPluginOperations
- WaitingForPluginOperationsPartiallyFailed
- Finalizing
- FinalizingPartiallyFailed
and from above non final phases to
- Completed
- PartiallyFailed
Once backup/restore is in some phase it will already be reconciled again periodically and do not need additional retry
- WaitingForPluginOperations
- WaitingForPluginOperationsPartiallyFailed
## Detailed Design
Relevant reconcilers will have `resourceTimeout time.Duration` added to its struct and to parameters of New[Backup|Restore]XReconciler functions.
pkg/cmd/server/server.go in `func (s *server) runControllers(..) error` also update the New[Backup|Restore]XCReconciler with added duration parameters using value from existing `--resource-timeout` server flag.
Current calls to kube.PatchResource involving status patch will be replaced with kube.PatchResourceWithRetriesOnErrors added to package `kube` below.
Calls where there is a ...client.Patch() will be wrapped with client.RetriesPhasePatchFuncOnErrors() added to package `client` below.
pkg/util/kube/client.go
```go
// PatchResourceWithRetries patches the original resource with the updated resource, retrying when the provided retriable function returns true.
func PatchResourceWithRetries(maxDuration time.Duration, original, updated client.Object, kbClient client.Client, retriable func(error) bool) error {
return veleroPkgClient.RetryOnRetriableMaxBackOff(maxDuration, func() error { return PatchResource(original, updated, kbClient) }, retriable)
}
// PatchResourceWithRetriesOnErrors patches the original resource with the updated resource, retrying when the operation returns an error.
func PatchResourceWithRetriesOnErrors(maxDuration time.Duration, original, updated client.Object, kbClient client.Client) error {
return PatchResourceWithRetries(maxDuration, original, updated, kbClient, func(err error) bool {
// retry using DefaultBackoff to resolve connection refused error that may occur when the server is under heavy load
// TODO: consider using a more specific error type to retry, for now, we retry on all errors
// specific errors:
// - connection refused: https://pkg.go.dev/syscall#:~:text=Errno(0x67)-,ECONNREFUSED,-%3D%20Errno(0x6f
return err != nil
})
}
```
pkg/client/retry.go
```go
// CapBackoff provides a backoff with a set backoff cap
func CapBackoff(cap time.Duration) wait.Backoff {
if cap < 0 {
cap = 0
}
return wait.Backoff{
Steps: math.MaxInt,
Duration: 10 * time.Millisecond,
Cap: cap,
Factor: retry.DefaultBackoff.Factor,
Jitter: retry.DefaultBackoff.Jitter,
}
}
// RetryOnRetriableMaxBackOff accepts a patch function param, retrying when the provided retriable function returns true.
func RetryOnRetriableMaxBackOff(maxDuration time.Duration, fn func() error, retriable func(error) bool) error {
return retry.OnError(CapBackoff(maxDuration), func(err error) bool { return retriable(err) }, fn)
}
// RetryOnErrorMaxBackOff accepts a patch function param, retrying when the error is not nil.
func RetryOnErrorMaxBackOff(maxDuration time.Duration, fn func() error) error {
return RetryOnRetriableMaxBackOff(maxDuration, fn, func(err error) bool { return err != nil })
}
```
## Alternatives Considered
- Requeuing InProgress backups that is not known by current velero instance to still be in progress as failed (attempted in [#7863](https://github.com/vmware-tanzu/velero/pull/7863))
- It was deemed as making backup restore flow hard to enhance for future reconciler updates such as adding cancel or adding parallel backups.
## Security Considerations
None
## Compatibility
Retry should only trigger a restore or backup that is already in progress and not patching successfully by current instance. Prior InProgress backups/restores will not be re-processed and will remain stuck InProgress until there is another velero server (re)start.
## Implementation
There is a past implementation in [#7845](https://github.com/vmware-tanzu/velero/pull/7845/) where implementation for this design will be based upon.

**Note:** The Velero server automatically patches the `skipImmediately` field back to `false` after it's been used. This is because `skipImmediately` is designed to be a one-time operation rather than a persistent state. When the controller detects that `skipImmediately` is set to `true`, it:
1. Sets the flag back to `false`
2. Records the current time in `schedule.Status.LastSkipped`

The `LastSkipped` field is crucial for the schedule controller to determine the next run time. When a backup is skipped, this timestamp is used instead of `LastBackup` to calculate when the next backup should occur, ensuring the schedule maintains its intended cadence even after skipping a backup.
When `schedule.spec.SkipImmediately` is `true`, `LastSkipped` will be set to the current time, and `schedule.spec.SkipImmediately` set to nil so it can be used again.
The `getNextRunTime()` function below is updated so `LastSkipped` which is after `LastBackup` will be used to determine next run time.

# Adding Support For VolumeAttributes in Resource Policy
## Abstract
Currently [Velero Resource policies](https://velero.io/docs/main/resource-filtering/#creating-resource-policies) are only supporting "Driver" to be filtered for [CSI volume conditions](https://github.com/vmware-tanzu/velero/blob/8e23752a6ea83f101bd94a69dcf17f519a805388/internal/resourcepolicies/volume_resources_validator.go#L28)
If user want to skip certain CSI volumes based on other volume attributes like protocol or SKU, etc, they can't do it with the current Velero resource policies. It would be convenient if Velero resource policies could be extended to filter on volume attributes along with existing driver filter in the resource policies `conditions` to handle the backup of volumes just by `some specific volumes attributes conditions`.
## Background
As of Today, Velero resource policy already provides us the way to filter volumes based on the `driver` name. But it's not enough to handle the volumes based on other volume attributes like protocol, SKU, etc.
## Example:
- Provision Azure NFS: Define the Storage class with `protocol: nfs` under storage class parameters to provision [CSI NFS Azure File Shares](https://learn.microsoft.com/en-us/azure/aks/azure-files-csi#nfs-file-shares).
- User wants to back up AFS (Azure file shares) but only want to backup `SMB` type of file share volumes and not `NFS` file share volumes.
## Goals
- We are only bringing additional support in the resource policy to only handle volumes during backup.
- Introducing support for `VolumeAttributes` filter along with `driver` filter in CSI volume conditions to handle volumes.
## Non-Goals
- Currently, only handles volumes, and does not support other resources.
## Use-cases/Scenarios
### Skip backup volumes by some volume attributes:
Users want to skip PV with the requirements:
- option to skip specified PV on volume attributes type (like Protocol as NFS, SMB, etc)
### Sample Storage Class Used to create such Volumes
```
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: azurefile-csi-nfs
provisioner: file.csi.azure.com
allowVolumeExpansion: true
parameters:
protocol: nfs
```
## High-Level Design
Modifying the existing Resource Policies code for [csiVolumeSource](https://github.com/vmware-tanzu/velero/blob/8e23752a6ea83f101bd94a69dcf17f519a805388/internal/resourcepolicies/volume_resources_validator.go#L28C6-L28C22) to add the new `VolumeAttributes` filter for CSI volumes and adding validations in existing [csiCondition](https://github.com/vmware-tanzu/velero/blob/8e23752a6ea83f101bd94a69dcf17f519a805388/internal/resourcepolicies/volume_resources.go#L150) to match with volume attributes in the conditions from Resource Policy config map and original persistent volume.
## Detailed Design
The volume resources policies should contain a list of policies which is the combination of conditions and related `action`, when target volumes meet the conditions, the related `action` will take effection.
Below is the API Design for the user configuration:
### API Design
```go
type csiVolumeSource struct {
Driver string `yaml:"driver,omitempty"`
// [NEW] CSI volume attributes
VolumeAttributes map[string]string `yaml:"volumeAttributes,omitempty"`
}
```
The policies YAML config file would look like this:
```yaml
version: v1
volumePolicies:
- conditions:
csi:
driver: disk.csi.azure.com
action:
type: skip
- conditions:
csi:
driver: file.csi.azure.com
volumeAttributes:
protocol: nfs
action:
type: skip`
```
### New Supported Conditions
#### VolumeAttributes
Existing CSI Volume Condition can now add `volumeAttributes` which will be key and value pairs.
Specify details for the related volume source (currently only csi driver is supported filter)
```yaml
csi: // match volume using `file.csi.azure.com` and with volumeAttributes protocol as nfs
driver: file.csi.azure.com
volumeAttributes:
protocol: nfs

# Velero Generic Data Path Load Affinity Enhancement 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][1]. 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
The implemented [VGDP LoadAffinity design][3] already defined the a structure `LoadAffinity` in `--node-agent-configmap` parameter. The parameter is used to set the affinity of the backupPod of VGDP.
There are still some limitations of this design:
* The affinity setting is global. Say there are two StorageClasses and the underlying storage can only provision volumes to part of the cluster nodes. The supported nodes don't have intersection. Then the affinity will definitely not work in some cases.
* The old design focuses on the backupPod affinity, but the restorePod also needs the affinity setting.
As a result, create this design to address the limitations.
## Goals
- Enhance the node affinity of VGDP instances for volume snapshot data movement: add per StorageClass node affinity.
- Enhance the node affinity of VGDP instances for volume snapshot data movement: support the or logic between affinity selectors.
- Define the behaviors of node affinity of VGDP instances in node-agent for volume snapshot data movement restore, when the PVC restore doesn't require delay binding.
## Non-Goals
- It is also beneficial to support VGDP instances affinity for PodVolume backup/restore, this will be implemented after the PodVolume micro service completes.
## Solution
This design still uses the ConfigMap specified by `velero node-agent` CLI's parameter `--node-agent-configmap` to host the node affinity configurations.
Upon the implemented [VGDP LoadAffinity design][3] introduced `[]*LoadAffinity` structure, this design add a new field `StorageClass`. This field is optional.
* If the `LoadAffinity` element's `StorageClass` doesn't have value, it means this element is applied to global, just as the old design.
* If the `LoadAffinity` element's `StorageClass` has value, it means this element is applied to the VGDP instances' PVCs use the specified StorageClass.
* The `LoadAffinity` element whose `StorageClass` has value has higher priority than the `LoadAffinity` element whose `StorageClass` doesn't have value.
```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"`
}
```
``` go
type LoadAffinity struct {
// NodeSelector specifies the label selector to match nodes
NodeSelector metav1.LabelSelector `json:"nodeSelector"`
// StorageClass specifies the VGDPs the LoadAffinity applied to. If the StorageClass doesn't have value, it applies to all. If not, it applies to only the VGDPs that use this StorageClass.
StorageClass string `json:"storageClass"`
}
```

#### LoadAffinity interacts with LoadAffinityPerStorageClass
``` json
{
"loadAffinity": [
{
"nodeSelector": {
"matchLabels": {
"beta.kubernetes.io/instance-type": "Standard_B4ms"
}
}
},
{
"nodeSelector": {
"matchExpressions": [
{
"key": "kubernetes.io/os",
"values": [

],
"operator": "In"
}
]
},
"storageClass": "kibishii-storage-class"
},
{
"nodeSelector": {
"matchLabels": {
"beta.kubernetes.io/instance-type": "Standard_B8ms"
}
},
"storageClass": "kibishii-storage-class"
}
]
}
```
This sample demonstrates how the `loadAffinity` elements with `StorageClass` field and without `StorageClass` field setting work together.
If the VGDP mounting volume is created from StorageClass `kibishii-storage-class`, its pod will run Linux nodes or instance type as `Standard_B8ms`.
The other VGDP instances will run on nodes, which instance type is `Standard_B4ms`.
#### LoadAffinity interacts with BackupPVC
``` json
{
"loadAffinity": [
{
"nodeSelector": {
"matchLabels": {
"beta.kubernetes.io/instance-type": "Standard_B4ms"
}
},
"storageClass": "kibishii-storage-class"
},
{
"nodeSelector": {
"matchLabels": {
"beta.kubernetes.io/instance-type": "Standard_B2ms"
}
},
"storageClass": "worker-storagepolicy"
}
],
"backupPVC": {
"kibishii-storage-class": {
"storageClass": "worker-storagepolicy"
}
}
}
```
Velero data mover supports to use different StorageClass to create backupPVC by [design](https://github.com/vmware-tanzu/velero/pull/7982).
In this example, if the backup target PVC's StorageClass is `kibishii-storage-class`, its backupPVC should use StorageClass `worker-storagepolicy`. Because the final StorageClass is `worker-storagepolicy`, the backupPod uses the loadAffinity specified by `loadAffinity`'s elements with `StorageClass` field set to `worker-storagepolicy`. backupPod will be assigned to nodes, which instance type is `Standard_B2ms`.
#### LoadAffinity interacts with RestorePVC

{
"loadAffinity": [
{
"nodeSelector": {
"matchLabels": {
"beta.kubernetes.io/instance-type": "Standard_B4ms"
}
},
"storageClass": "kibishii-storage-class"
}
],
"restorePVC": {
"ignoreDelayBinding": false
}
}
```
##### StorageClass's bind mode is WaitForFirstConsumer
``` yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: kibishii-storage-class
parameters:
svStorageClass: worker-storagepolicy
provisioner: csi.vsphere.vmware.com
reclaimPolicy: Delete
volumeBindingMode: WaitForFirstConsumer
```
If restorePVC should be created from StorageClass `kibishii-storage-class`, and it's volumeBindingMode is `WaitForFirstConsumer`.
Although `loadAffinityPerStorageClass` has a section matches the StorageClass, the `ignoreDelayBinding` is set `false`, the Velero exposer will wait until the target Pod scheduled to a node, and returns the node as SelectedNode for the restorePVC.
As a result, the `loadAffinityPerStorageClass` will not take affect.
##### StorageClass's bind mode is Immediate
``` yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: kibishii-storage-class
parameters:
svStorageClass: worker-storagepolicy
provisioner: csi.vsphere.vmware.com
reclaimPolicy: Delete
volumeBindingMode: Immediate
```
Because the StorageClass volumeBindingMode is `Immediate`, although `ignoreDelayBinding` is set to `false`, restorePVC will not be created according to the target Pod.
The restorePod will be assigned to nodes, which instance type is `Standard_B4ms`.

# VGDP Micro Service For fs-backup
## Glossary & Abbreviation
**VGDP**: Velero Generic Data Path. The collective modules that is introduced in [Unified Repository design][1]. Velero uses these modules to finish data transmission for various purposes. It includes uploaders and the backup repository.
**fs-backup**: Also known as pod volume backup (PVB)/pod volume restore (PVR). It is one of the primary backup methods built-in with Velero. It has been refactored in [Unified Repository design][1].
**PVB**: Pod Volume Backup, the internal name for backup part of fs-backup.
**PVR**: Pod Volume Restore, the internal name for restore part of fs-backup.
**Exposer**: Exposer is introduced in [Volume Snapshot Data Movement design][2] and is used to expose the volume snapshots/volumes for VGDP to access locally.
**VGDP MS**: VGDP Micro Service, it is introduced in [VGDP Micro Service For Volume Snapshot Data Movement][3]. It hosts VGDP instances in dedicated backup/restore pods, instead of in node-agent pods.
## Background
As described in [VGDP Micro Service For Volume Snapshot Data Movement][3], hosting VGDP instances in dedicated pods has solved many major problems and brought significant improvements in scalability. These improvements are also effective for fs-backup. And besides the benefits listed in [VGDP Micro Service For Volume Snapshot Data Movement][3], we can also see below ones specifically for fs-backup:
- This enables fs-backup to support Windows workloads. Windows doesn't support propagate mount, so the current fs-backup solution doesn't work for Windows nodes and Windows workloads. However, if the final host-path for the source volume is mounted to the VGDP MS pods, it should work.
- This enables fs-backup to reuse the existing VGDP features seamlessly, i.e., concurrency control, node selector, etc.
By moving all VGDP instances out of node-agent pods, we would further get prepared for below important features and improvements:
- NFS support: NFS volumes are mounted to VGDP MS pods, so node-agent pods don't need to restart when a new BSL is added.
- Performance improvement for Kopia uploader restore ([#7725][9]): dedicated cache volumes could be mounted to the VGDP MS pods, without affecting node-agent pods.
- Controllable resource usage for node-agent: node-agent pods are long running and so not suitable for data path activities as the OS usually reclaim memory in a lazy reclaim behavior, so the unused memory may be shown as occupied by node-agent pods, which misleads Kubernetes or other related sub system. After this change, node-agent pods no longer require large resource (CPU/memory) usage, so no obvious memory retain will be observed.
- Simplify node-agent configuration: host-path mounts, root user and privileged mode are no longer required by node-agent; and the configuration differences of node-agent for linux and Windows nodes could be eliminated.
## Goals
- Create a solution to make VGDP instances as micro services for fs-backup
- Modify the fs-backup workflow to offload the VGDP work from node-agent to the VGDP MS
- Create the mechanism for fs-backup to control and monitor the VGDP MS in various scenarios
## Non-Goals
- The current solution covers the VGDP Micro Service for fs-backup itself, the potentional features/improvements that rely on this solution will be covered by further designs and implementations.
## Overview
The solution is based on [VGDP Micro Service For Volume Snapshot Data Movement][3], the architecture is followed as is and existing components are not changed unless it is necessary.
Below diagram shows how these components work together:
![vgdp-ms-1.png](vgdp-ms-1.png)
Below lists the changed components, why and how:
**Pod-Volume Exposer**: A new exposer, pod-volume exposer is added. It retrieves the host path of the specific volume and then creates the backupPod/restorePod and mounts the host path to the pod. The command of the backupPod/restorePod is also changed to launch VGDP MS for PVB/PVR.
**PVB/PVR Controller**: The PVB/PVR controllers are refactored to work with podVolume exposer, VGDP-MS, etc. The controllers will also support Cancel and resume. So PVB/PVR CRD is also refactored to support these scenarios.
**PVB/PVR VGDP-MS**: New commands for PVB/PVR VGDP-MS are added. The VGDP instances are started in the backupPod/restorePod as result of the commands.
The VGDP Watcher and its mechanism are fully reused.
The [Node-agent concurrency][4] is reused to control the concurrency of VGDP MS for fs-backup. When there are too many volumes in the backup/restore, which takes too much computing resources(CPU, memory, etc.) or Kubernetes resources(pods, PVCs, PVs, etc.), users could set the concurrency in each node so as to control the total number of concurrent VGDP instances in the cluster.
## Detailed Design
### Exposer
As the old behavior, the host path (e.g., `/var/lib/kubelet/pods`) for the Kubernetes pods are mounted to node-agent pods, then the VGDP instances running in the same pods access the data through subdir of the host path for a specific volume, e.g., `/var/lib/kubelet/pods/<pod UID>/volumes/kubernetes.io~csi/<PVC name>/mount`. Therefore, a node-agent pod could access all volumes attached to the same node.
For the new implementation, the exposer retrieves the host path for a specific volume directly, and then mount that host path to the backupPod/restorePod. This also means that the backupPod/restorePod could only access the volume to be backed up or restored.
The exposer creates backupPod/restorePod and sets ```velero pod-volume``` as the command run by backupPod/restorePod. And `velero` image is used for the backupPod/restorePod.
There are sub commands varying from backup and restore:
```velero pod-volume backup --volume-path xxx --pod-volume-backup xxx --resource-timeout xxx --log-format xxx --log-level xxx```
Or:
```velero pod-volume restore --volume-path xxx --pod-volume-restore xxx --resource-timeout xxx --log-format xxx --log-level xxx```
Below are the parameters of the commands:
**volume-path**: Deliver the full path inside the backupPod/restorePod for the volume to be backed up/restored.
**pod-volume-backup**: PVB CR for this backup.
**pod-volume-restore**: PVR CR for this restore.
**resource-timeout**: resource-timeout is used to control the timeout for operations related to resources. It has the same meaning with the resource-timeout for node-agent.
**log-format** and **log-level**: This is to control the behavior of log generation inside VGDP-MS.
Below pod configurations are inherited from node-agent and set to backupPod/restorePod's spec:
- Volumes: Some configMaps will be mapped as volumes to node-agent, so we add the same volumes of node-agent to the backupPod/restorePod
- Environment Variables
- Security Contexts
Since the volume data is still accessed by host path, the backupPod/restorePod may still need to run in Privileged mode in some environments. Therefore, the Privileged mode setting which is a part of Security Contexts will be inherited from node-agent.
The root user is still required, especially by the restore (in order to restore the file system attributes, owners, etc.), so we will use root user for backupPod/restorePod.
As same as [VGDP Micro Service For Volume Snapshot Data Movement][3], the backupPod/restorePods's ```RestartPolicy``` is set to ```RestartPolicyNever```, so that once VGDP-MS terminates for any reason, backupPod/restorePod won't restart and the PVB/PVR is marked as one of the terminal phases (Completed/Failed/Cancelled) accordingly.
### VGDP Watcher
The VGDP watcher is fully reused, specifically, we still use the dual mode event watcher to watch the status change from backupPod/restorePod or the VGDP instance.
The AsyncBR adapter and its interface is also fully reused.
### VGDP-MS
The VGDP-MS that is represented by ```velero pod-volume``` keeps the same workflow as [VGDP Micro Service For Volume Snapshot Data Movement][3]:
![vgdp-ms-2.png](vgdp-ms-2.png)
**Start DUCR/DDCR Watcher**: The same as [VGDP Micro Service For Volume Snapshot Data Movement][3], except that it watches PVB/PVR CRs.
**Wait DUCR/DDCR InProgress**: The same as The same as [VGDP Micro Service For Volume Snapshot Data Movement][3], VGDP-MS won't start the VGDP instance until PVB/PVR CR turns to ```InProgress```.
**Record VGDP Starts**: The same as [VGDP Micro Service For Volume Snapshot Data Movement][3].
**VGDP Callbacks**: The same as [VGDP Micro Service For Volume Snapshot Data Movement][3].
**Record VGDP Ends**: The same as [VGDP Micro Service For Volume Snapshot Data Movement][3].
**Record VGDP Progress**: The same as [VGDP Micro Service For Volume Snapshot Data Movement][3].
**Set VGDP Output**: The same as [VGDP Micro Service For Volume Snapshot Data Movement][3].
The return message for VGDP completion is also reused, except that `VolMode` is always set to `PersistentVolumeFilesystem`:
```
type BackupResult struct {
SnapshotID string `json:"snapshotID"`
EmptySnapshot bool `json:"emptySnapshot"`
Source exposer.AccessPoint `json:"source,omitempty"`
}
```
```
type RestoreResult struct {
Target exposer.AccessPoint `json:"target,omitempty"`
}
```
```
type AccessPoint struct {
ByPath string `json:"byPath"`
VolMode uploader.PersistentVolumeMode `json:"volumeMode"`
}
```
And the mechanism and data struct for Progress update is also reused:
```
type Progress struct {
TotalBytes int64 `json:"totalBytes,omitempty"`
BytesDone int64 `json:"doneBytes,omitempty"`
}
```
### Log Collection
The log collection mechanism is the same as [VGDP Micro Service For Volume Snapshot Data Movement][3].
### Resource Control
The resource control mechanism is the same as [VGDP Micro Service For Volume Snapshot Data Movement][3].
### Restic Restore
As the current Restic path deprecation process, restore is still supported. On the other hand, we don't want to support Restic path for this new VGDP MS implementation.
Therefore, the legacy PVR controller and workflow is preserved for Restic path restore. The controller watches legacy PVRs only, and then launches the legacy workflow. Meawhile, the new PVR controller should skip legacy PVRs.
After Restic path is full deprecated, the code for the legacy controller and workflow should be removed.
### Velero Server Restarts
The backup/restore stays in InProgress phase during the running of PVB/PVR, no phase changes between completion of item iteration and completion of PVB/PVR. As a result, on Velero server restarts, there is no way to resume a backup/restore.
Therefore, the backup/restore will be be marked as Failed, which is the same as the old behavior. And it is still not as good as CSI snapshot data movement for which the backup/restore could be resumed as long as it has iterated all items.
By the meanwhile, there is indeed some improvements. As the old behavior, once the backup/restore is set as Failed on Velero server restart, the running PVB/PVR will be left there, as a result, the VGDP instances may run for a long time and take lots of resource for nothing; for the new implementation, PVB/PVR will be set as Cancel immediately after the backup/restore is set as Failed.
### node-agent Restarts
As the old behavior, once a node-agent pod restarts, all the PVBs/PVRs running in the same node will be set as Failed as there is no way to resume the VGDP instances for them.
For the new implementation, since the VGDP instances run in dedicated backupPods/restorePods without affected, the PVBs/PVRs will be resumed after node-agent restarts. This includes PVBs/PVRs in all phases.
The legacy PVRs handling Restic restore are processed by the old workflow, so they will still be set as Failed on node-agent restart.
### Windows Support
Windows nodes and workloads will be supported by following the same changes for CSI snapshot data movement as listed in [Velero Windows Support][7]. There are some additional changes particularly for PVB/PVR.
#### Restore Helper
PVR requires an init-container, called `restore-wait`, to run in the workload pod. There are default configurations for the container and users could customize them by the `pod-volume-restore` RIA plugin configMap.
The `pod-volume-restore` RIA is used to config the init-container, so it should support Windows pods for all the configurations.
Meanwhile, the customized options in the configMap should also support Windows pods. If an option is not suitable for Windows pods, it will be ignored by the RIA.
By default, the init-container uses `velero` image with a binary called `velero-restore-helper` inside, so that binary should be compiled and assembled to the `velero` image for Windows.
#### Privileged mode
Privileged pods are implemented by [HostProcess Pods][8] on Windows and need to be specially configured. And there are many constrains for it.
As one of the constrains, HostProcess pods supports Windows service accounts only. As a result, restore will not be able to support it until [#8423][10] is fixed, otherwise, the restored files are not usable by workloads which run under genneral container users, e.g., `containerUser` or `containerAdministrator`.
Therefore, as the current implementation, fs-backup will not support Windows workloads in the environments where Privileged mode is required. A limitation should be documented.
## node-agent
node-agent is required to host the PVB/PVR controller which reconciles PVB/PVR and operates PVB/PVR in other steps before the VGDP instance is started, i.e., Accept, Expose, etc.
node-agent still requires host path mount because of two deprecating features [in-tree storage provider support deprecation][5] and [emptyDir volume support deprecation][6]. As a result, Privileged mode and root user are still required in some environments. Therefore, we will keep the node-agent deamonset as is, until the two deprecations complete.
## CRD Changes
In order to support the VGDP MS workflow, some elements in the PVB/PVR CRDs are added or extended:
- New phases are added for PVB/PVR: `PodVolumeBackupPhaseAccepted`, `PodVolumeBackupPhasePrepared`, `PodVolumeBackupPhaseCanceling`, `PodVolumeBackupPhaseCanceled`; `PodVolumeRestorePhaseAccepted`, `PodVolumeRestorePhasePrepared`, `PodVolumeRestorePhaseCanceling`, `PodVolumeRestorePhaseCanceled`.
- New fields are added to PVB/PVR spec to support cancel: `Cancel bool`
- New fields are added to PVB/PVR spec to support the accept phase and processing: `AcceptedTimestamp *metav1.Time`
- A new field, which records the node the PVR is running, is added to PVR Status: `Node string`
New changes happen to Backup/Restore CRDs.

# VGDP Micro Service For Volume Snapshot Data Movement
## Glossary & Abbreviation
**VGDP**: Velero Generic Data Path. The collective of modules that is introduced in [Unified Repository design][1]. Velero uses these modules to finish data transmission for various purposes. It includes uploaders and the backup repository.
**Volume Snapshot Data Movement**: The backup/restore method introduced in [Volume Snapshot Data Movement design][2]. It backs up snapshot data from the volatile and limited production environment into the durable, heterogeneous and scalable backup storage.
**VBDM**: Velero Built-in Data Mover as introduced in [Volume Snapshot Data Movement design][2], it is the built-in data mover shipped along with Velero.
**Exposer**: Exposer is introduced in [Volume Snapshot Data Movement design][2] and is used to expose the volume snapshots/target volumes for VGDP to access locally.
## Background
As the architecture introduced in [Volume Snapshot Data Movement design][2], VGDP instances are running inside the node-agent pods, however, more and more use cases require to run the VGDP instances in dedicated pods, or in another word, make them as micro services, the benefits are as below:
- This avoids VGDP to access volume data through host path, while host path access involves privilege escalations in some environments (e.g., must run under privileged mode), which makes challenge to users.
- This enable users to to control resource (i.e., cpu, memory) request/limit in a granular manner, e.g., control them per backup/restore of a volume
- This increases the resilience, crash of one VGDP activity won't affect others
- In the cases that the backup storage must be represented by a Kubernetes persistent volumes (i.e., nfs storage, [COSI][3]), this avoids to dynamically mount the persistent volumes to node-agent pods and cause node-agent pods to restart (this is not accepted since node-agent lose it current state after its pods restart)
- This prevents unnecessary full backup. Velero's fs uploaders support file level incremental backup by comparing the file name and metadata. However, at present the files are visited by host path, while pod and PVC's ID are part of the host path, so once the pod is recreated, the same file is regarded as a different file since the pod's ID has been changed. If the fs uploader is in a dedicated pod and files are visited by pod's volume path, files' full path are not changed after pod restarts, so incremental backups could continue.
## Goals
- Create a solution to make VGDP instances as micro services
- Modify the VBDM to offload the VGDP work from node-agent to the VGDP micro service
- Create the mechanism for VBDM to control and monitor the VGDP micro services in various scenarios
## Non-Goals
- The current solution covers Volume Snapshot Data Movement backup/restore type only, even though VGDP is also used by pod volume backup. It is less possible to do this for pod volume backup, since it must run inside the source workload pods.
- The current solution covers VBDM only. 3rd data movers still follow the **Replacement** section of [Volume Snapshot Data Movement design][2]. That is, 3rd data movers handle the DUCR/DDCR on their own and they are free to make themselves micro service style or monolith service style.
## Overview
The solution is based on [Volume Snapshot Data Movement design][2], the architecture is followed as is and existing components are not changed unless it is necessary.
Below lists the changed components, why and how:
**Exposer**: Exposer is to expose the snapshot/target volume as a path/device name/endpoint that are recognizable by VGDP. Varying from the type of snapshot/target volume, a pod may be created as part of the expose. Now, since we run the VGDP instance in a separate pod, a pod is created anyway, we assume exposer creates a pod all the time and make the appropriate exposing configurations to the pod so that VGDP instance could access the snapshot/target volume locally inside the pod. The pod is still called as backupPod or restorePod.
Then we need to change the command the backupPod/restorePod is running, the command launches VGDP-MS (VGDP Micro Service, see below) when the container starts up.
For CSI snapshot, the backupPod/restorePod is created as the result of expose, the only thing left is to change the backupPod/restorePod's image.
**VBDM**: VBDM contains the data mover controller, while the controller calls the Exposer and launches the VGDP instances. Now, since the VGDP instance is launched by the backupPod/restorePod, the controller should not launch the VGDP instance again. However, the controller still needs to monitor and control the VGDP instance. Moreover, in order to avoid any contest situations, the controller is still the only place to update DUCRs and DDCRs.
Besides the changes to above existing components, we need to add below new components:
**VGDP Watcher**: We create a new module to help the data mover controller to watch activities of the VGDP instance in the backupPod/restorePod. VGDP Watcher is a part of VBDM.
**VGDP-MS**: VGDP Micro Service is the binary for the command backupPod/restorePod runs. It accepts the parameters and then launches the VGDP instance according to the request type, specifically, backup or restore. VGDP-MS also runs other modules to sync-up with the data mover controller. VGDP-MS is also a part of VBDM.
Below diagram shows how these components work together:
![vgdp-ms-1.png](vgdp-ms-1.png)
The [Node-agent concurrency][4] is still used to control the concurrency of VGDP micro services. When there are too many volumes in the backup/restore, which takes too much computing resources(CPU, memory, etc.) or Kubernetes resources(pods, PVCs, PVs, etc.), users could set the concurrency in each node so as to control the total number of concurrent VGDP micro services in the cluster.
## Detailed Design
### Exposer
At present, the exposer creates backupPod/restorePod and sets ```velero-helper pause``` as the command run by backupPod/restorePod.
Now, VGDP-MS command will be used, and the ```velero``` image will be running inside the backupPod/restorePod. The command is like below:
```velero data-mover backup --volume-path xxx --volume-mode xxx --data-upload xxx --resource-timeout xxx --log-format xxx --log-level xxx```
Or:
```velero data-mover restore --volume-path xxx --volume-mode xxx --data-download xxx --resource-timeout xxx --log-format xxx --log-level xxx```
The first one is for backup and the other one is for restore.
Below are the parameters of the commands:
**volume-path**: Deliver the full path inside the backupPod/restorePod for the volume to be backed up/restored.
**volume-mode**: Deliver the mode for the volume be backed up/restored, at present either ```Filesystem``` mode or ```Block``` mode.
**data-upload**: DUCR for this backup.
**data-download**: DDCR for this backup.
**resource-timeout**: resource-timeout is used to control the timeout for operations related to resources. It has the same meaning with the resource-timeout for node-agent.
**log-format** and **log-level**: This is to control the behavior of log generation inside VGDP-MS.
In order to have the same capability and permission with node-agent, below pod configurations are inherited from node-agent and set to backupPod/restorePod's spec:
- Volumes: Some configMaps will be mapped as volumes to node-agent, so we add the same volumes of node-agent to the backupPod/restorePod
- Environment Variables
- Security Contexts
We may not actually need all the capabilities in the VGDP-MS as the node-agent. At present, we just duplicate all of them, if we find any problem in future, we can filter out the capabilities that are not required by VGDP-MS.
The backupPod/restorePod is not run in Privileged mode as it is not required since the volumes are visisted by pod path.
The root user is still required, especially by the restore (in order to restore the file system attributes, owners, etc.), so we will use root user for backupPod/restorePod.
We set backupPod/restorePod's ```RestartPolicy``` to ```RestartPolicyNever```, so that once VGDP-MS terminates in any reason, backupPod/restorePod won't restart and the DUCR/DDCR is marked as one of the terminal phases (Completed/Failed/Cancelled) accordingly.
### VGDP Watcher
#### Dual mode event watch
The primary task of VGDP Watcher is to watch the status change from backupPod/restorePod or the VGDP instance, so as to inform the data mover controller in below situations:
- backupPod/restorePod starts
- VGDP instance starts
- Progress update
- VGDP instance completes/fails/cancelled
- backupPod/restorePod stops
We use two mechanism to make the watch:
**Pod Phases**: VGDP Watcher watches the backupPod/restorePod's phases updated by Kubernetes. That is, VGDP Watcher creates an informer to watch the pod resource for the backupPod/restorePod and detect that the pod reaches to one of the terminated phases (i.e., PodSucceeded, PodFailed). We also check the availability & status of the backupPod/restorePod at the beginning of the watch so as to detect the starting of the backupPod/restorePod.
**Custom Kubernetes Events**: VGDP-MS generates Kubernetes events and associates them to the DUCR/DDCR at the time of VGDP instance starting/stopping and progress update, then VGDP Watcher creates another informer to watch the Event resource associated to the DUCR/DDCR.
Pod Phases watch covers the entire lifecycle of the backupPod/restorePod, but we don't know the status of the VGDP instance through it; and it can only deliver information by then end of the pod lifecycle.
Custom Event watch generates details of the VGDP instances and the events could be generated any time; but it cannot generate notifications before VGDP starts or in the case that VGDP crashes or shutdown abnormally.
Therefore, we adopt the both mechanisms to VGDP Watcher. In the end, there will be two sources generating the result of VGDP-MS:
- The termination message of backupPod/restorePod
- The message along with the VGDP Instance Completes/Fails/Cancelled event
On the one hand, in some cases only the backupPod/restorePod's termination message is available, e.g., the backupPod/restorePod crashes or or backupPod/restorePod quits before VGDP instance is started. So we refer to the first mechanism to get the notifications.
On the other hand, if they are both available, we have the results from them for mutual verification.
Conclusively, under the help of VGDP Watcher, data mover controller starts VGDP-MS controllably and waits until VGDP-MS ends under any circumstances.
#### AsyncBR adapter
VGDP Watcher needs to notify the data mover controller when one of the watched event happens, so that the controller could do the operations as if it receives the same callbacks from VGDP as the current behavior. In order not to break the existing code logics of data mover controllers, we make VGDP Watcher as an adapter of AsyncBR which is the interface implemented by VGDP and called by the data mover controller.
Since the parameters to call VGDP Watcher is different from the ones to call VGDP, we change the AsyncBR interface to hide some parameters from one another, the new interface is as below:
```
type AsyncBR interface {
// Init initializes an asynchronous data path instance
Init(ctx context.Context, res *exposer.ExposeResult, param interface{}) error
// StartBackup starts an asynchronous data path instance for backup
StartBackup(dataMoverConfig map[string]string, param interface{}) error
// StartRestore starts an asynchronous data path instance for restore
StartRestore(snapshotID string, dataMoverConfig map[string]string) error
// Cancel cancels an asynchronous data path instance
Cancel()
// Close closes an asynchronous data path instance
Close(ctx context.Context)
}
```
Some parameters are hidden into ```param```, but the functions and calling logics are not changed.
VGDP Watcher should be launched by the data mover controller before VGDP instance starts, otherwise, multiple corner problems may happen. E.g., VGDP-MS may run the VGDP instance immediately after the backupPod/restorePod is launched and completes it before the data mover controller starts VGDP Watcher, as a result, multiple informs are missed from VGDP Watcher.
Therefore, the controller launches VGDP Watcher first and then set the DUCR/DDCR to ```InProgress```; on the other hand, VGDP-MS waits DUCR/DDCR turns to ```InProgress``` before running the VGDP instance.
### VGDP-MS
VGDP-MS is represented by ```velero data-mover``` subcommand and has its own subcommand ```backup``` and ```restore```.
Below diagram shows the VGDP-MS workflow:
![vgdp-ms-2.png](vgdp-ms-2.png)
**Start DUCR/DDCR Watcher**: VGDP-MS needs to watch the corresponding DUCR/DDCR so as to react on some events happening to the DUCR/DDCR. E.g., when the data movement is cancelled, a ```Cancel``` flag is set to the DUCR/DDCR, by watching the DUCR/DDCR, VGDP-MS is able to see it and cancel the VGDP instance.
**Wait DUCR/DDCR InProgress**: As mentioned above, VGDP-MS won't start the VGDP instance until DUCR/DDCR turns to ```InProgress```, by which time VGDP Watcher has been started.
**Record VGDP Starts**: This generates the VGDP Instance Starts event.
**VGDP Callbacks**: When VGDP comes to one of the terminal states (i.e., completed, failed, cancelled), the corresponding callback is called.
**Record VGDP Ends**: This generates the VGDP Instance Completes/Fails/Cancelled event, and also generates backupPod/restorePod termination message.
**Record VGDP Progress**: This periodically generates/updates the Progress event with totalBytes/bytesDone to indicate the progress of the data movement.
**Set VGDP Output**: This writes the termination message to the backupPod/restorePod's termination log (by default, it is written to ```/dev/termination-log```).
If VGDP completes, VGDP Instance Completes event and backupPod/restorePod termination shares the same message as below:
```
type BackupResult struct {
SnapshotID string `json:"snapshotID"`
EmptySnapshot bool `json:"emptySnapshot"`
Source exposer.AccessPoint `json:"source,omitempty"`
}
```
```
type RestoreResult struct {
Target exposer.AccessPoint `json:"target,omitempty"`
}
```
```
type AccessPoint struct {
ByPath string `json:"byPath"`
VolMode uploader.PersistentVolumeMode `json:"volumeMode"`
}
```
The existing VGDP result structures are actually being reused, we just add the json markers so that they can be marshalled.
As mentioned above, once VGDP-MS ends in any way, the backupPod/restorePod terminates and never restarts, so the end of VGDP-MS means the end of DU/DD.
For Progress update, the existing Progress structure is being reused:
```
type Progress struct {
TotalBytes int64 `json:"totalBytes,omitempty"`
BytesDone int64 `json:"doneBytes,omitempty"`
}
```
### Log Collection
During the running of VGDP instance, some logs are generated which are important for troubleshooting. This includes all the logs generated by the uploader and repository. Therefore, it is important to collect these logs.
On the other hand, the logs are now generated in the backupPod/restorePod, while the backupPod/restorePod is deleted immediately after the data movement completes. Therefore, by default, ```velero debug``` is not able to collect these logs.
As a solution, we use logrus's hook mechanism to redirect the backupPod/restorePod's logs into node-agent's log, so that ```velero debug``` could collect VGDP logs as is without any changes.
Below diagram shows how VGDP logs are redirected:
![vgdp-ms-3.png](vgdp-ms-3.png)
This log redirecting mechanism is thread safe since the hook acquires the write lock before writing the log buffer, so it guarantees that in the node-agent log there is no corruptions after redirecting the log, and the redirected logs and the original node-agent logs are not projected into each other.
### Resource Control
The CPU/memory resource of backupPod/restorePod is configurable, which means users are allowed to configure resources per volume backup/restore.
By default, the [Best Effort policy][5] is used, and users are allowed to change it through the ConfigMap specified by `velero node-agent` CLI's parameter `--node-agent-configmap`. Specifically, we add below structures to the ConfigMap:
```
type Configs struct {
// PodResources is the resource config for various types of pods launched by node-agent, i.e., data mover pods.
PodResources *PodResources `json:"podResources,omitempty"`
}
type PodResources struct {
CPURequest string `json:"cpuRequest,omitempty"`
MemoryRequest string `json:"memoryRequest,omitempty"`
CPULimit string `json:"cpuLimit,omitempty"`
MemoryLimit string `json:"memoryLimit,omitempty"`
}
```
The string values must mactch Kubernetes Quantity expressions; for each resource, the "request" value must not be larger than the "limit" value. Otherwise, if any one of the values fail, all the resource configurations will be ignored.
The configurations are loaded by node-agent at start time, so users can change the values in the configMap any time, but the changes won't effect until node-agent restarts.
## node-agent
node-agent is still required. Even though VGDP is now not running inside node-agent, node-agent still hosts the data mover controller which reconciles DUCR/DDCR and operates DUCR/DDCR in other steps before the VGDP instance is started, i.e., Accept, Expose, etc.
Privileged mode and root user are not required for node-agent anymore by Volume Snapshot Data Movement, however, they are still required by PVB(PodVolumeBackup) and PVR(PodVolumeRestore). Therefore, we will keep the node-agent deamonset as is, for any users who don't use PVB/PVR and have concern about the privileged mode/root user, they need to manually modify the deamonset spec to remove the dependencies.
## CRD Changes
There is no changes to any CRD.
## Installation Changes
No changes to installation, the backupPod/restorePod's configurations are all inherited from node-agent.
## Upgrade
Upgrade is not impacted.
## CLI
CLI is not changed.

# Add Support for VolumeGroupSnapshots
This proposal outlines the design and implementation plan for incorporating VolumeGroupSnapshot support into Velero. The enhancement will allow Velero to perform consistent, atomic snapshots of groups of Volumes using the new Kubernetes [VolumeGroupSnapshot API](https://kubernetes.io/blog/2024/12/18/kubernetes-1-32-volume-group-snapshot-beta/). This capability is especially critical for stateful applications that rely on multiple volumes to ensure data consistency, such as databases and analytics workloads.
## Glossary & Abbreviation
Terminology used in this document:
- VGS: VolumeGroupSnapshot
- VS: VolumeSnapshot
- VGSC: VolumeGroupSnapshotContent
- VSC: VolumeSnapshotContent
- VGSClass: VolumeGroupSnapshotClass
- VSClass: VolumeSnapshotClass
## Background
Velero currently enables snapshot-based backups on an individual Volume basis through CSI drivers. However, modern stateful applications often require multiple volumes for data, logs, and backups. This distributed data architecture increases the risk of inconsistencies when volumes are captured individually. Kubernetes has introduced the VolumeGroupSnapshot(VGS) API [(KEP-3476)](https://github.com/kubernetes/enhancements/pull/1551), which allows for the atomic snapshotting of multiple volumes in a coordinated manner. By integrating this feature, Velero can offer enhanced disaster recovery for multi-volume applications, ensuring consistency across all related data.
## Goals
- Ensure that multiple related volumes are snapshotted simultaneously, preserving consistency for stateful applications via VolumeGroupSnapshots(VGS) API.
- Integrate VolumeGroupSnapshot functionality into Veleros existing backup and restore workflows.
- Allow users to opt in to volume group snapshots via specifying the group label.
## Non-Goals
- The proposal does not require a complete overhaul of Veleros CSI integration, it will extend the current mechanism to support group snapshots.
- No any changes pertaining to execution of Restore Hooks
## High-Level Design
### Backup workflow:
#### Accept the label to be used for VGS from the user:
- Accept the label from the user, we will do this in 3 ways:
- Firstly, we will have a hard-coded default label key like `velero.io/volume-group-snapshot` that the users can directly use on their PVCs.
- Secondly, we will let the users override this default VGS label via a velero server arg, `--volume-group-nsaphot-label-key`, if needed.
- And Finally we will have the option to override the default label via Backup API spec, `backup.spec.volumeGroupSnapshotLabelKey`
- In all the instances, the VGS label key will be present on the backup spec, this makes the label key accessible to plugins during the execution of backup operation.
- This label will enable velero to filter the PVC to be included in the VGS spec.
- Users will have to label the PVCs before invoking the backup operation.
- This label would act as a group identifier for the PVCs to be grouped under a specific VGS.
- It will be used to collect the PVCs to be used for a particular instance of VGS object.
**Note:**
- Modifying or adding VGS label on PVCs during an active backup operation may lead to unexpected or undesirable backup results. To avoid inconsistencies, ensure PVC labels remain unchanged throughout the backup execution.
- Label Key Precedence: When determining which label key to use for grouping PVCs into a VolumeGroupSnapshot, Velero applies overrides in the following order (highest to lowest):
- Backup API spec (`backup.spec.volumeGroupSnapshotLabelKey`)
- Server flag (`--volume-group-snapshot-label-key`)
- Built-in default (`velero.io/volume-group-snapshot`)
Whichever key wins this precedence is then injected into the Backup spec so that all Velero plugins can uniformly discover and use it during the backup execution.
#### Changes to the Existing PVC ItemBlockAction plugin:
- Currently the PVC IBA plugin is applied to PVCs and adds the RelatedItems for the particular PVC into the ItemBlock.
- At first it checks whether the PVC is bound and VolumeName is non-empty.
- Then it adds the related PV under the list of relatedItems.
- Following on, the plugin adds the pods mounting the PVC as relatedItems.
- Now we need to extend this PVC IBA plugin to add the PVCs to be grouped for a particular VGS object, so that they are processed together under an ItemBlock by Velero.
- First we will check if the PVC that is being processed by the plugin has the user specified VGS label.
- If it is present then we will execute a List call in the namespace with the label as a matching criteria and see if this results in any PVCs (other than the current one).
- If there are PVCs matching the criteria then we add the PVCs to the relatedItems list.
- This helps in building the ItemBlock we need for VGS processing, i.e. we have the relevant pods and PVCs in the ItemBlock.
**Note:** The ItemBlock to VGS relationship will not always be 1:1. There might be scenarios when the ItemBlock might have multiple VGS instances associated with it.
Lets go over some ItemBlock/VGS scenarios that we might encounter and visualize them for clarity:
1. Pod Mounts: Pod1 mounts both PVC1 and PVC2.
Grouping: PVC1 and PVC2 share the same group label (group: A)
ItemBlock: The item block includes Pod1, PVC1, and PVC2.
VolumeGroupSnapshot (VGS): Because PVC1 and PVC2 are grouped together by their label, they trigger the creation of a single VGS (labeled with group: A).

P1 -->|mounts| PVC2

```
2. Pod Mounts: Pod1 mounts each of the four PVCs.
Grouping:
Group A: PVC1 and PVC2 share the same grouping label (group: A).
Group B: PVC3 and PVC4 share the grouping label (group: B)
ItemBlock: All objects (Pod1, PVC1, PVC2, PVC3, and PVC4) are collected into a single item block.
VolumeGroupSnapshots:
PVC1 and PVC2 (group A) point to the same VGS (VGS (group: A)).
PVC3 and PVC4 (group B) point to a different VGS (VGS (group: B)).

Grouping:
Group A: PVC1 and PVC2
Group B: PVC3
ItemBlock: All objects-Pod1, Pod2, PVC1, PVC2, and PVC3, are collected into a single item block.

PVC3 -- "Group B" --> VGS_B[VGS Group B]
```
#### Updates to CSI PVC plugin:
The CSI PVC plugin now supports obtaining a VolumeSnapshot (VS) reference for a PVC in three ways, and then applies common branching for datamover and nondatamover workflows:
- Scenario 1: PVC has a VGS label and no VS (created via the VGS workflow) exists for its volume group:
- Determine VGSClass: The plugin will pick `VolumeGroupSnapshotClass` by following the same tier based precedence as it does for individual `VolumeSnapshotClasses`:
- Default by Label: Use the one VGSClass labeled
```yaml
metadata:
labels:
velero.io/csi-volumegroupsnapshot-class: "true"
```
whose `spec.driver` matches the CSI driver used by the PVCs.
- Backuplevel Override: If the Backup CR has an annotation
```yaml
metadata:
annotations:
velero.io/csi-volumegroupsnapshot-class_<driver>: <className>
```
(with <driver> equal to the PVCs CSI driver), use that class.
- PVClevel Override: Finally, if the PVC itself carries an annotation
```yaml
metadata:
annotations:
velero.io/csi-volume-group-snapshot-class: <className>
```
and that class exists, use it.
At each step, if the plugin finds zero or multiple matching classes, VGS creation is skipped and backup fails.
- Create VGS: The plugin creates a new VolumeGroupSnapshot (VGS) for the PVCs volume group. This action automatically triggers creation of the corresponding VGSC, VS, and VSC objects.
- Wait for VS Status: The plugin waits until each VS (one per PVC in the group) has its `volumeGroupSnapshotName` populated. This confirms that the snapshot controller has completed its work. `CSISnapshotTimeout` will be used here.
- Update VS Objects: Once the VS objects are provisioned, the plugin updates them by removing VGS owner references and VGS-related finalizers, and by adding backup metadata labels (including BackupName, BackupUUID, and PVC name). These labels are later used to detect an existing VS when processing another PVC of the same group.
- Patch and Cleanup: The plugin patches the deletionPolicy of the VGSC to "Retain" (ensuring that deletion of the VGSC does not remove the underlying VSC objects or storage snapshots) and then deletes the temporary VGS and VGSC objects.
- Scenario 2: PVC has a VGS label and a VS created via an earlier VGS workflow already exists:
- The plugin lists VS objects in the PVCs namespace using backup metadata labels (BackupUID, BackupName, and PVCName).
- It verifies that at least one VS has a nonempty `volumeGroupSnapshotName` in its status.
- If such a VS exists, the plugin skips creating a new VGS (or VS) and proceeds with the legacy workflow using the existing VS.
- If a VS is found but its status does not indicate it was created by the VGS workflow (i.e. its `volumeGroupSnapshotName` is empty), the backup for that PVC is failed, resulting in a partially failed backup.
- Scenario 3: PVC does not have a VGS label:
- The legacy workflow is followed, and an individual VolumeSnapshot (VS) is created for the PVC.
- Common Branching for Datamover and Nondatamover Workflows:
- Once a VS reference (`vsRef`) is determined—whether through the VGS workflow (Scenario 1 or 2) or the legacy workflow (Scenario 3)—the plugin then applies the common branching:
- Nondatamover Case: The VS reference is directly added as an additional backup item.
- Datamover Case: The plugin waits until the VSs associated VSC snapshot handle is ready (using the configured CSISnapshotTimeout), then creates a DataUpload for the VSPVC pair. The resulting DataUpload is then added as an additional backup item.

Restore workflow:
- No changes required for the restore workflow.
## Detailed Design
Backup workflow:
- Accept the label to be used for VGS from the user as a server argument:
- Set a default VGS label key to be used:
```go
// default VolumeGroupSnapshot Label
defaultVGSLabelKey = "velero.io/volume-group-snapshot"
```
- Add this as a server flag and pass it to backup reconciler, so that we can use it during the backup request execution.
```go
flags.StringVar(&c.DefaultVGSLabelKey, "volume-group-snapshot-label-key", c.DefaultVGSLabelKey, "Label key for grouping PVCs into VolumeGroupSnapshot")
```
- Update the Backup CRD to accept the VGS Label Key as a spec value:
```go
// VolumeGroupSnapshotLabelKey specifies the label key to be used for grouping the PVCs under
// an instance of VolumeGroupSnapshot, if left unspecified velero.io/volume-group-snapshot is used
// +optional
VolumeGroupSnapshotLabelKey string `json:"volumeGroupSnapshotLabelKey,omitempty"`
```
- Modify the [`prepareBackupRequest` function](https://github.com/openshift/velero/blob/8c8a6cccd78b78bd797e40189b0b9bee46a97f9e/pkg/controller/backup_controller.go#L327) to set the default label key as a backup spec if the user does not specify any value:
```go
if len(request.Spec.VolumeGroupSnapshotLabelKey) == 0 {
// set the default key value
request.Spec.VolumeGroupSnapshotLabelKey = b.defaultVGSLabelKey
}
```
- Changes to the Existing [PVC ItemBlockAction plugin](https://github.com/vmware-tanzu/velero/blob/512199723ff95d5016b32e91e3bf06b65f57d608/pkg/itemblock/actions/pvc_action.go#L64) (Update the GetRelatedItems function):
```go
// Retrieve the VGS label key from the Backup spec.
vgsLabelKey := backup.Spec.VolumeGroupSnapshotLabelKey
if vgsLabelKey != "" {
// Check if the PVC has the specified VGS label.
if groupID, ok := pvc.Labels[vgsLabelKey]; ok {
// List all PVCs in the namespace with the same label key and value (i.e. same group).
pvcList := new(corev1api.PersistentVolumeClaimList)
if err := a.crClient.List(context.Background(), pvcList, crclient.InNamespace(pvc.Namespace), crclient.MatchingLabels{vgsLabelKey: groupID}); err != nil {
return nil, errors.Wrap(err, "failed to list PVCs for VGS grouping")
}
// Add each matching PVC (except the current one) to the relatedItems.

if groupPVC.Name == pvc.Name {
continue
}

## Implementation
This design proposal is targeted for velero 1.16.
The implementation of this proposed design is targeted for velero 1.17.
**Note:**
- VGS support isn't a requirement on restore. The design does not have any VGS related elements/considerations in the restore workflow.
## Requirements and Assumptions
- Kubernetes Version:
- Minimum: v1.32.0 or later, since the VolumeGroupSnapshot API goes beta in 1.32.
- Assumption: CRDs for `VolumeGroupSnapshot`, `VolumeGroupSnapshotClass`, and `VolumeGroupSnapshotContent` are already installed.
- VolumeGroupSnapshot API Availability:
- If the VGS API group (`groupsnapshot.storage.k8s.io/v1beta1`) is not present, Velero backup will fail.
- CSI Driver Compatibility
- Only CSI drivers that implement the VolumeGroupSnapshot admission and controller support this feature.
- Upon VGS creation, we assume the driver will atomically snapshot all matching PVCs; if it does not, the plugin may time out.
## Performance Considerations
- Use VGS if you have many similar volumes that must be snapped together and you want to minimize API/server load.
- Use individual VS if you have only a few volumes, or want onevolume failures to be isolated.
## Testing Strategy
- Unit tests: We will add targeted unit tests to cover all new code paths—including existing-VS detection, VGS creation, legacy VS fallback, and error scenarios.
- E2E tests: For E2E we would need, a Kind cluster with a CSI driver that supports group snapshots, deploy an application with multiple PVCs, execute a Velero backup and restore, and verify that VGS is created, all underlying VS objects reach ReadyToUse, and every PVC is restored successfully.

# Add Label Selector as a criteria for Volume Policy
## Abstract
Veleros volume policies currently support several criteria (such as capacity, storage class, and volume source type) to select volumes for backup. This update extends the design by allowing users to specify required labels on the associated PersistentVolumeClaim (PVC) via a simple key/value map. At runtime, Velero looks up the PVC (when a PV has a ClaimRef), extracts its labels, and compares them with the user-specified map. If all key/value pairs match, the volume qualifies for backup.
## Background
PersistentVolumes (PVs) in Kubernetes are typically bound to PersistentVolumeClaims (PVCs) that include labels (for example, indicating environment, application, or region). Basing backup policies on these PVC labels enables more precise control over which volumes are processed.
## Goals
- Allow users to specify a simple key/value mapping in the volume policy YAML so that only volumes whose associated PVCs contain those labels are selected.
- Support policies that target volumes based on criteria such as environment=production or region=us-west.
## Non-Goals
- No changes will be made to the actions (skip, snapshot, fs-backup) of the volume policy engine. This update focuses solely on how volumes are selected.
- The design does not support other label selector operations (e.g., NotIn, Exists, DoesNotExist) and only allows for exact key/value matching.
## Use-cases/scenarios
1. Environment-Specific Backup:
- A user wishes to back up only those volumes whose associated PVCs have labels such as `environment=production` and `app=database`.
- The volume policy specifies a pvcLabels map with those key/value pairs; only volumes whose PVCs match are processed.
```yaml
volumePolicies:
- conditions:
pvcLabels:
environment: production
app: database
action:
type: snapshot
```
2. Region-Specific Backup:
- A user operating in multiple regions wants to back up only volumes in the `us-west` region.
- The policy includes `pvcLabels: { region: us-west }`, so only PVs bound to PVCs with that label are selected.
```yaml
volumePolicies:
- conditions:
pvcLabels:
region: us-west
action:
type: snapshot
```
3. Automated Label-Based Backups:
- An external system automatically labels new PVCs (for example, `backup: true`).
- A volume policy with `pvcLabels: { backup: true }` ensures that any new volume whose PVC contains that label is included in backup operations.
```yaml
version: v1
volumePolicies:
- conditions:
pvcLabels:
backup: true
action:
type: snapshot
```
## High-Level Design
1. Extend Volume Policy Schema:
- The YAML schema for volume conditions is extended to include an optional field pvcLabels of type `map[string]string`.
2. Implement New Condition Type:
- A new condition, `pvcLabelsCondition`, is created. It implements the `volumeCondition` interface and simply compares the user-specified key/value pairs with the actual PVC labels (populated at runtime).
3. Update Structured Volume:
- The internal representation of a volume (`structuredVolume`) is extended with a new field `pvcLabels map[string]string` to store the labels from the associated PVC.
- A new helper function (or an updated parsing function) is used to perform a PVC lookup when a PV has a ClaimRef, populating the pvcLabels field.
4. Integrate with Policy Engine:
- The policy builder is updated to create and add a `pvcLabelsCondition` if the policy YAML contains a `pvcLabels` entry.
- The matching entry point uses the updated `structuredVolume` (populated with PVC labels) to evaluate all conditions, including the new PVC labels condition.
## Detailed Design
1. Update Volume Conditions Schema: Define the conditions struct with a simple map for PVC labels:
```go
// volumeConditions defines the current format of conditions we parse.
type volumeConditions struct {
Capacity string `yaml:"capacity,omitempty"`
StorageClass []string `yaml:"storageClass,omitempty"`
NFS *nFSVolumeSource `yaml:"nfs,omitempty"`
CSI *csiVolumeSource `yaml:"csi,omitempty"`
VolumeTypes []SupportedVolume `yaml:"volumeTypes,omitempty"`
// New field: pvcLabels for simple exact-match filtering.
PVCLabels map[string]string `yaml:"pvcLabels,omitempty"`
}
```
2. New Condition: `pvcLabelsCondition`: Implement a condition that compares expected labels with those on the PVC:
```go
// pvcLabelsCondition defines a condition that matches if the PVC's labels contain all the specified key/value pairs.
type pvcLabelsCondition struct {
labels map[string]string
}
func (c *pvcLabelsCondition) match(v *structuredVolume) bool {
if len(c.labels) == 0 {
return true // No label condition specified; always match.
}
if v.pvcLabels == nil {
return false // No PVC labels found.
}
for key, expectedVal := range c.labels {
if actualVal, exists := v.pvcLabels[key]; !exists || actualVal != expectedVal {
return false
}
}
return true
}
func (c *pvcLabelsCondition) validate() error {
// No extra validation needed for a simple map.
return nil
}
```
3. Update `structuredVolume`: Extend the internal volume representation with a field for PVC labels:
```go
// structuredVolume represents a volume with parsed fields.
type structuredVolume struct {
capacity resource.Quantity
storageClass string
// New field: pvcLabels stores labels from the associated PVC.
pvcLabels map[string]string
nfs *nFSVolumeSource
csi *csiVolumeSource
volumeType SupportedVolume
}
```
4. Update PVC Lookup `parsePVWithPVC`: Modify the PV parsing function to perform a PVC lookup:
```go
func (s *structuredVolume) parsePVWithPVC(pv *corev1.PersistentVolume, client crclient.Client) error {
s.capacity = *pv.Spec.Capacity.Storage()
s.storageClass = pv.Spec.StorageClassName
if pv.Spec.NFS != nil {
s.nfs = &nFSVolumeSource{
Server: pv.Spec.NFS.Server,
Path: pv.Spec.NFS.Path,
}
}
if pv.Spec.CSI != nil {
s.csi = &csiVolumeSource{
Driver: pv.Spec.CSI.Driver,
VolumeAttributes: pv.Spec.CSI.VolumeAttributes,
}
}
s.volumeType = getVolumeTypeFromPV(pv)
// If the PV is bound to a PVC, look it up and store its labels.
if pv.Spec.ClaimRef != nil {
pvc := &corev1.PersistentVolumeClaim{}
err := client.Get(context.Background(), crclient.ObjectKey{
Namespace: pv.Spec.ClaimRef.Namespace,
Name: pv.Spec.ClaimRef.Name,
}, pvc)
if err != nil {
return errors.Wrap(err, "failed to get PVC for PV")
}
s.pvcLabels = pvc.Labels
}
return nil
}
```
5. Update the Policy Builder: Add the new condition to the policy if pvcLabels is provided:
```go
func (p *Policies) BuildPolicy(resPolicies *ResourcePolicies) error {
for _, vp := range resPolicies.VolumePolicies {
con, err := unmarshalVolConditions(vp.Conditions)
if err != nil {
return errors.WithStack(err)
}
volCap, err := parseCapacity(con.Capacity)
if err != nil {
return errors.WithStack(err)
}
var volP volPolicy
volP.action = vp.Action
volP.conditions = append(volP.conditions, &capacityCondition{capacity: *volCap})
volP.conditions = append(volP.conditions, &storageClassCondition{storageClass: con.StorageClass})
volP.conditions = append(volP.conditions, &nfsCondition{nfs: con.NFS})
volP.conditions = append(volP.conditions, &csiCondition{csi: con.CSI})
volP.conditions = append(volP.conditions, &volumeTypeCondition{volumeTypes: con.VolumeTypes})
// If a pvcLabels map is provided, add the pvcLabelsCondition.
if con.PVCLabels != nil && len(con.PVCLabels) > 0 {
volP.conditions = append(volP.conditions, &pvcLabelsCondition{labels: con.PVCLabels})
}
p.volumePolicies = append(p.volumePolicies, volP)
}
p.version = resPolicies.Version
return nil
}
```
6. Update the Matching Entry Point: Use the updated PV parsing that performs a PVC lookup:
```go
func (p *Policies) GetMatchAction(res interface{}, client crclient.Client) (*Action, error) {
volume := &structuredVolume{}
switch obj := res.(type) {
case *corev1.PersistentVolume:
if err := volume.parsePVWithPVC(obj, client); err != nil {
return nil, errors.Wrap(err, "failed to parse PV with PVC lookup")
}
case *corev1.Volume:
volume.parsePodVolume(obj)
default:
return nil, errors.New("failed to convert object")
}
return p.match(volume), nil
}
```
Note: The matching loop (p.match(volume)) iterates over all conditions (including our new pvcLabelsCondition) and returns the corresponding action if all conditions match.

# 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 controller-runtime core reconciler logic already prevents the same resource from being reconciled by two different reconciler threads, so we don't need to worry about concurrency issues at the controller level.
The workerPool reference will be moved from the backupReconciler to the backupRequest, since this will now be backup-specific, and the initialization code for the worker pool will be moved from the reconciler init into the backup reconcile. This worker pool will be shut down upon exiting the Reconcile method.
### 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.
