i've never heard of anyone having a corrupted file system because
of a bad dump, and this is across a large number of systems and
years.  while this case is certainly possible, it seems to be
highly improbable.

we've supported dump to raid for a long while now, and it's very
useful.  dump to cgd should work, too.
