What you don't get out of this scenario is a truly independent copy of the 
data.  In the event of a disk failure, you're out everything.  I know the raid 
people would like you to believe that double drive failures never happen, but 
in reality they only almost never happen.  Or, what if the sprinkler system in 
your computer room goes haywire? (etc., etc., etc.)

To be complete, I would need something that would have a virtually unlimited 
number of multiple snapshots on a separate server from the RW.  That way I 
could store the backup data in a separate building and have both on-line 
backups and the data portion of my disaster recovery plan taken care.  I 
suppose replicated RW volumes and multiple .backup clones would get me there 
also...

Yes, I'm asking alot.
