You can use (e.g.) (assuming /dev/fd0a is a 5" HD floppy, and /dev/wd0a
is mounted on /):

	dump 0ufB /dev/fd0a 1200 /

I used this for the better part of a year.  I suggest seeing the man pages
for dump and restore before doing this, though.

BEWARE:  I found that restore is not happy if the directory portion of the
dump exceeds one dump volume.  This depends on the number of files you
have, but it happened to me roughly when my dump got up to about 100 floppies.
I had to hack restore before it would restore from such a dump.  This
can be embarrassing if you don't have a running system to hack with.
Dump and restore are really awful programs, so hacking them is not pleasant.

I had posted my hack for restore to the old patchkit, but it didn't ever
appear there and in retrospect I am sure that it was not the right fix.
I don't really know now whether the bug is in dump or in restore.
To my knowledge, no one has yet fixed this problem.  It doesn't concern me
as much any more since a friend gave me an Archive tape drive to use
instead.
