	At our site we have about 30 gigabytes of disk space. We use
dump and restore exclusively for our backup needs. The way we get
multiple dumps to is as follows:
	
	o Use the "non rewind" device for our 8mm tape unit.
	o call a script from cron that consecutively performs a 
	  backup to the 8mm tape unit. We can backup all 20 of our
	  drives to two tapes this way. It is only a daily bakup,
	  but it works unattended. 

Since the tape dosn't rewind after each dump, the next dump continues
where the previous dump ended.
-
To restore just use the "s" feature of restore. This skips file marks
to the desired dump on the tape.

Restore can handle a file tree easily. Use the interactive switch when
you start the restore (i.e restore -i /dev/nrmt2h ). You will be placed
at the the "restore>" prompt. To select a tree simply "add" the node
where the tree begins:

	restore> add node

As far as VMS backup goes, I am not aware of any products out there to
support that type of environment.
