Backup Sets containing SQL database backups may expire prematurely.
When the system databases are automatically switched to a full backup method during an incremental backup job, it removes the dependency on the prior backups from the associated user database backup set. Since the prior full and incremental backups are no longer part of the dependency chain, they can be deleted if the retention period expires before the depending incremental backups.
