Filesystem-Level Backups with Velero#

Create a backup#

  1. Set MSR4 to Read-Only Mode.

    Before initiating the backup, set MSR4 to Read-Only mode to prevent new data from being written during the process, minimizing inconsistencies.

    1. Log in to MSR4 as an administrator.
    2. Navigate to Administration -> Configuration.
    3. Under System Settings, enable the Repository Read-Only option.
    4. Click Save to apply the changes.

  2. Optional: Label Redis-Related Resources for Exclusion.

    To avoid backing up ephemeral data, exclude Redis-related resources from the backup.

    1. Label the Redis Pod:

      kubectl -n <MSR4-NAMESPACE> label pod <REDIS-POD-NAME> velero.io/exclude-from-backup=true

    2. Repeat the labeling process for the Redis PersistentVolumeClaim (PVC) and PersistentVolume (PV):

      kubectl -n <MSR4-NAMESPACE> label pvc <REDIS-PVC-NAME> velero.io/exclude-from-backup=true
kubectl -n <MSR4-NAMESPACE> label pv <REDIS-PV-NAME> velero.io/exclude-from-backup=true

  3. Create a backup.

    Create a Full Backup

    Run the following command to create a full backup:

    velero backup create msr4-full-backup --include-namespaces harbor --default-volumes-to-fs-backup --wait

    Create an Incremental Backup

    After the full backup, incremental backups happen automatically. They capture only the changes since the last backup:

    velero backup create msr4-incremental-backup --include-namespaces harbor --default-volumes-to-fs-backup --wait

  4. Complete backup by unsetting Read-Only mode.

    Once the backup is complete, revert MSR4 to its normal operational state:

    1. Navigate to Administration -> Configuration.
    2. Under System Settings, disable the Repository Read-Only option by unchecking it.
    3. Click Save to apply the changes.
