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.
