Here's what I use on 60m tape:
dump 0usdf 2352 593480 /dev/rst0

Divide 2352 by 12 and you get roughly 60m. The 's' param seems to be in
inches, not feet.

Dump/restore don't grok DCLZ compression. Unless you have some readout
on your drive it will basically just boost your throughput. You will also
find the file recovery speed of restore to be somewhat ridiculous, it doesn't
block address the tape, it streams it.
