    If an online catalog backup policy includes both full backups and incremental backups, the disaster recovery email may indicate either a full backup or an incremental backup for recovery. An incremental backup recovery completely recovers the entire catalog because it references information from the last full backup. You don't need to first recover the last full catalog backup, then follow with subsequent incremental backups.

    I'll try it on my server when I get a few mins.
