Here's what my vendor told me to use:

dump <level>dsbf 43000 12000 64 /dev/nrst1 <filesystem>

The "64" can be any multiple of 8 from 8 to 120, but 64 is easy to
remember and document.  This commandline gives sensible figures for
portions of a tape used (204.64MB on 0.09 tapes, for example, said a
recent dump).  Yes, you could use a huge figure for length as well,
unless you plan on having a 2.2GB filesystem. :-)

I've been running with a commandline like this for about eight months
from 13 microvaxen and 40 sun3, sun4, and sun386 machines.  No
problem, as Alf would say.

Just another exabyte hacker,
