And you shouldn't be using RAID5 or RAID6 at all if your drives are

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.<br>
