Hi.  I would *love* to automate backups, so that all filesystems are backed-up
to one 8mm tape.  However, the non-rewindable tape devices seem to rewind
anyways.

For instance, I type:

	backup -0 -f/dev/rmt1.1 /local

and when it finishes, it says something like:

	dump finished
	rewinding tape
	dump finished

Isn't /dev/rmt1.1 a non-rewindable tape device???


I would like to have a script something like the following to backup
everything onto one tape:

	backup -0 -f/dev/rmt1.1 /local
	backup -0 -f/dev/rmt1.1 /u/staff
	backup -0 -f/dev/rmt1.1 /u/ugrad
	backup -0 -f/dev/rmt1.1 /u/grad
	backup -0 -f/dev/rmt1.1 /u/faculty
	backup -0 -f/dev/rmt1 /usr

Assuming, I eventually get non-rewinding tape devices to *not* rewind,
should the last tape device be a rewindable tape device, such as /dev/rmt1 ???

Am I missing some logic or common logic here?  I've searched through info with
no luck.  Any hints would be greatly appreciated.

Thanks in advance!
