     We addressed this by decreasing our snapshot interval from 1 day
to 1 hour. We rarely have a snapshot bigger than a few GB now. I keep
meaning to put together a snapshot script that takes a new snapshot
when the amount of changed data increases to a certain point (for
example, take a snapshot whenever the snapshot would contain 250 MB of
data). Not enough round toits with all the other broken stuff to fix
:-(
