This classifies a rollback point as either a normal user-created snapshot or a backup type, defaulting to normal. This distinction matters because backup-type rollback points may be handled differently by retention or automated backup policies than the ad hoc normal snapshots an operator creates before a change. For example, an automated nightly job might create rollback points of type backup that are retained on a fixed schedule, while an admin manually saving a snapshot before a change creates one of type normal.
