      Description

      In MDL-28657 was introduced a new naming style for backup files. It allowed the course short names to be used instead of IDs.

      Unfortunately it created a regression (MDL-33812) because those new backups using short names were not being deleted during cron. MDL-33812 introduces a new naming convention which forces the ID to be in the backup name along with the short name or not.

      The goal of this issue is to find a way to nicely deleting the previously created backups:

      • Make sure there are no collision as 2 short names can be confused. Example: my-course and my-course-2.
      • Make sure we keep backups according to the setting backup_auto_keep. This means combining both new and old backups.
