My experience is nearly the opposite of this.  I've never lost any
active fossil data.  And I agree that once data is archived to venti,
it is safe.  But the daily archiving to venti can fail - sometimes
with "archWalk:" error messages and no dump made, but more often
silently leaving a dump with corrupted metadata in one or two
directories preventing access to anything below them in the tree.
More details in http://9fans.net/archive/2009/04/135 - I still haven't
tracked down the cause but I suspect a data race somewhere.  It's an
irritation rather than a disaster because I've always been able to
patch up the bad metadata by hand.  I quite enjoy a bit of disk
surgery now and then to keep my hand in.
