NOTE

       /INCREMENTAL is valid only in restore operations. It is not
       related to the /NOINCREMENTAL qualifier, which is valid only
       in BACKUP save operations.

    Allows you to restore a disk volume from a series of incremental
    save sets. When processed correctly, the output disk volume
    will contain the same files it contained when the most recent
    incremental save operation was performed. BACKUP does not create
    files on the output disk volume that were deleted in the period
    in which the incremental backups were performed.

    When you use /INCREMENTAL in a restore operation, you must
    specify a device as the output specifier; file specifications
    are invalid. When you specify the /INCREMENTAL qualifier, BACKUP
    restores files using the /BY_OWNER=ORIGINAL qualifier.
