     I have 3 symbolics machines (two ivories, one non-ivory); one of
     the ivories has an exabyte drive on it.  I'd like to back up all
     three LMFSes onto the exabyte.  Is there a simple way to do this
     (preferably without a lot of mouse action)?

   I bet you really want to write some script which will automatically
   dump all three LMFSii without any operator intervention.
   Unfortunately, I don't know of any such batch facility.  Perhaps
   someone else on SLUG has already hacked up something.  Failing that,
   you could try to read the LMFS sources.  There is some good stuff in
   there.

The real problem is that you have to perform a LMFS backup on the
machine whose filesystem is being backed up.  You can connect to a
tape drive attached to some other machine, but you are still going to
have to run three separate backup operations for the three machines.
