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.
