Manually Synchronize Backup Volumes

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 provides a way for you to manually synchronize backup volumes with the backup target.

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.
