Is it a DLT 4000 or 7000 or, even, 8000 drive?
If it's DLT 4000, you will have difficulties - DV video can not be
compressed (I usually see an increase in volume with large digital video
collections) and so you'd need 10 tapes.
If you limit the amount of data to about 140 GB, you should be able to
fit that on 7 DLT tapes, but you'd need a very long night to save and
verify that: ~ 3.5 hours per tape to write, the same time to read
(verify), that's 7 hours - times 7 tapes...
Just make sure you use a tape drive fast enough for your backup window...
