Options
/DEVICE
Backs up or restores (with the /RESTORE option) an entire volume in image
mode.
The backup operation backs up everything on a volume, including empty blocks
and directory blocks. You can back up volumes to disks, diskettes, or magtapes.
BUP copies the input volume to one or more output volumes. If there is more
data than will fit on the output volume, BUP verifies the output data it has
already copied (if you have specified /VERIFY) and then prompts you to remove
the backup volume and insert another. BUP repeats this process until the entire
input volume has been copied.
Examples
1. The following command backs up a DU0 volume to several diskettes, using
DU1. The backup volumes will contain the saveset file DU0.BUP when the
backup operation is complete:
.BACKUP/DEVICE DU0: DU1:
