The Incremental qualifier restores a database from an incremental
    backup file.

    Use the Incremental qualifier only when you have first issued an
    RMU Restore command that names the full backup file that was the
    basis for this incremental backup file. Each incremental backup
    file is tied to a particular full backup file.

    After restoring both the full and the incremental backup files,
    you have restored the database to the condition it was in when
    you performed the incremental database backup operation.

    By default, RMU Restore performs a full restore operation on the
    backup file.

    You cannot specify the After_Journal or Just_Corrupt qualifier
    with the Incremental qualifier.
