The message Delete backup aborted means that someone or something tries to delete an existing backup, which fails. In your case, I guess that you had Swift backup configured earlier, created a backup, then switched to Ceph. However, who/what wants to delete the backup and why, I can't say.

Perhaps you can list backups then force-delete whatever you see? Or clean the backups from the database.
