We dump our machines (including several Alliant FX/8s) incrementally
during the day.  There is the possibility that files can get lost
when the machine is up.  It's a risk we live with.  However, we do
level 0 dumps once a month and the machines are single-user when
that happens to insure good dump tapes so that we never lose more
than a month of work at the very worst.  Generally I think you would
be safe, but it might be reasonable to try and schedule the dumps
done while the machine is up when people are not logged in (like
early morning or late evening).
	Good luck,
