Highlights

The maintenance work for kopia/restic backup repositories is run in jobs

Since velero started using kopia as the approach for filesystem-level backup/restore, we've noticed an issue when velero connects to the kopia backup repositories and performs maintenance, it sometimes consumes excessive memory that can cause the velero pod to get OOM Killed. To mitigate this issue, the maintenance work will be moved out of velero pod to a separate kubernetes job, and the user will be able to specify the resource request in "velero install".

Volume Policies are extended to support more actions to handle volumes

In an earlier release, a flexible volume policy was introduced to skip certain volumes from a backup. In v1.14 we've made enhancement to this policy to allow the user to set how the volumes should be backed up. The user will be able to set "fs-backup" or "snapshot" as value of “action" in the policy and velero will backup the volumes accordingly. This enhancement allows the user to achieve a fine-grained control like "opt-in/out" without having to update the target workload. For more details please refer to https://velero.io/docs/v1.14/resource-filtering/#supported-volumepolicy-actions

Node Selection for Data Movement Backup

In velero the data movement flow relies on datamover pods, and these pods may take substantial resources and keep running for a long time. In v1.14, the user will be able to create a configmap to define the eligible nodes on which the datamover pods are launched. For more details refer to https://velero.io/docs/v1.14/data-movement-backup-node-selection/

VolumeInfo metadata for restored volumes

In v1.13, we introduced volumeinfo metadata for backup to help velero CLI and downstream adopter understand how velero handles each volume during backup. In v1.14, similar metadata will be persisted for each restore. velero CLI is also updated to bring more info in the output of "velero restore describe".

"Finalizing" phase is introduced to restores

The "Finalizing" phase is added to the state transition flow to restore, which helps us fix several issues: The labels added to PVs will be restored after the data in the PV is restored via volumesnapshotter. The post restore hook will be executed after datamovement is finished.

Certificate-based authentication support for Azure

Besides the service principal with secret(password)-based authentication, Velero introduces the new support for service principal with certificate-based authentication in v1.14.0. This approach enables you to adopt a phishing resistant authentication by using conditional access policies, which better protects Azure resources and is the recommended way by Azure.

Runtime and dependencies

  • Golang runtime: v1.22.2
  • kopia: v0.17.0

Limitations/Known issues

  • For the external BackupItemAction plugins that take snapshots for PVs, such as vsphere plugin. If the plugin checks the value of the field "snapshotVolumes" in the backup spec as a criteria for snapshot, the settings in the volume policy will not take effect. For example, if the "snapshotVolumes" is set to False in the backup spec, but a volume meets the condition in the volume policy for "snapshot" action, because the plugin will not check the settings in the volume policy, the plugin will not take snapshot for the volume. For more details please refer to #7818

Breaking changes

  • CSI plugin has been merged into velero repo in v1.14 release. It will be installed by default as an internal plugin, and should not be installed via "–plugins " parameter in "velero install" command.
  • The default resource requests and limitations for node agent are removed in v1.14, to make the node agent pods have the QoS class of "BestEffort", more details please refer to #7391
  • There's a change in namespace filtering behavior during backup: In v1.14, when the includedNamespaces/excludedNamespaces fields are not set and the labelSelector/OrLabelSelectors are set in the backup spec, the backup will only include the namespaces which contain the resources that match the label selectors, while in previous releases all namespaces will be included in the backup with such settings. More details refer to #7105
  • Patching the PV in the "Finalizing" state may cause the restore to be in "PartiallyFailed" state when the PV is blocked in "Pending" state, while in the previous release the restore may end up being in "Complete" state. For more details refer to #7866
