You should have a standalone BACKUP kit that came with your OpenVMS
distribution kit; however, depending on the type of media you have, standalone
BACKUP boots faster if you build it on the system disk or a user disk. The
installation and upgrade supplement for your computer contains instructions for
building and booting standalone BACKUP on several types of media.
This section provides information about building standalone BACKUP on a disk
or tape and using it to back up your system disk.
11.17.2.1 Building Standalone BACKUP on a Disk (VAX Only)
Standalone BACKUP boots faster on disk than it does on tape. For this reason,
you should create a standalone BACKUP kit on disk.
You can build standalone BACKUP on either the system disk or a user disk. If
you build standalone BACKUP on a user disk, the kit occupies more disk space
than if you build it on the system disk. This is because certain files that boot the
system already exist on the system disk.
