      Hey there,
      I encountered following:
      My Full Backup interval is 28 and my Backup Retention is 29. But after the new Full Backup interval began and the new full backup was created the next delta backup seems to point the old full Backup. Why do I think so?

      • The old Full Backup was not deleted on the remote although it dissappeared in XOA.
      • The latest change date of the old full Backup is AFTER the new full backup.

      Remote Files:

      XOA available Restore Backups

      Is this something to worry about? I'm afraid of deleting the old Full Backup.
      If this is an error: How to solve this?

        @Hannes_5253 As new delta backups are added old ones are merged into the old full backup and not just removed. So the old full backup will have a newer date because it's modified as the old delta backups are merged into it.

        You should have one or two full backups on disk (but not the restore list). The old deltas are merged into the old full until there is a newer full backup AND all older deltas are gone and it's just newer deltas after the newer full backup.

        Deltas (for XO) always work back to older fulls not forward to newer fulls.
