Synchronize Backup Volumes Manually

    After creating a backup, Longhorn creates a backup volume that corresponds to the original volume (on which the backup is based). A backup volume is an object in the backupstore that contains multiple backups of the same volume.

    Earlier Longhorn versions poll and update all backup volumes at a fixed interval. Longhorn v1.6.2 provides a way for you to manually synchronize backup volumes with the backup target.

    Important: You must set up a backup target and verify that a backup volume was created before attempting to synchronize. Longhorn returns an error when no backup target and backup volume exist.

    • Synchronize all backup volumes:

      1. On the Longhorn UI, go to Backup.
      2. Click Sync All Backup Volumes.

    • Synchronize a single backup volume:

      1. On the Longhorn UI, go to Backup.
      2. Select a backup volume.
      3. Click Sync Backup Volume.

    To check if synchronization was successful, click the name of the backup volume on the Backup screen.
