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.
