And you shouldn't be using RAID5 or RAID6 at all if your drives are 
750-1000GB or larger.

Mail and database servers would be two good places to make use of 
snapshotting filesystems.  Note that some email systems that use message 
stores go insane if the message store is not in the state that the rest 
of the email system presumes it's in, so you have to make sure that your 
backup/recovery scheme doesn't capture messages and message 
metadata/index in different states.
