There are three RMU Backup commands, as follows:

    o  An RMU Backup command without the After_Journal qualifier
       creates a database backup file.

    o  An RMU Backup command with the After_Journal qualifier creates
       a backup of the after-image journal (.aij) file. The .aij
       can reside on disk or on tape. The RMU Backup command with
       the After_Journal qualifier supports a two-stage journaling
       technique that saves disk space and creates a backup journal
       on tape.

    o  An RMU Backup command with the Plan qualifier allows you to
       execute a List_Plan previously created with a parallel backup
       operation. This form of the Backup command does not accept a
       database name as a parameter. Instead, it requires the name of
       a list plan.
