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/.
