If you looked at the URL's I sent earlier you would see that Sun also
recommends *not* to use ufsdump in problematic situations. I'm sorry but
anecdotal evidence that it's ok just isn't good enough for me at work
(me at home is different) ... not when there's clear indications that some
people*do* have problems with it.

If it's not a big deal, why does fssnap exist ? Yes there are other uses
for fssnap (for example to overcome the consistency problem of
file-by-file backups), but I suspect that if ufsdump was problem free
you wouldn't see it.

Yes but what qualifies as "low load" ? A number please (and I'm really
asking Sun who'll probably say zero)."low load" means different things
to different people.
