Right. I started to say something about that earlier (I have an
automated b/u script I wrote way-back-when that takes advantage of the
snapshot facility) but decided that mentioning that to the OP might lead
to some unexpected hardships for him/her. I decided that just letting
h{im | er } know that it didn't have the full FS was a better choice of
information to pass on.

And in all honesty, it's been so long since I read up on it (vers 1,
IIRC) and looked at the script, I really didn't feel qualified to
suggest anything useful with any certainty.
