SnapDrive and SME give you the ability
to do true online backups of Exchange without a visible outage and with
most of the I/O and backup processing happening off-host, and by integrating
with the Exchange backup API allows easy recovery of messages and/or whole
mailboxes from snapshots.
Without these tools, you can still run
Exchange on iSCSI, but your backup options are limited to:
1) Traditional "host-based"
backups, preferably using the appropriate Exchange module for your backup
products to allow "online" backups, providing you don't mind
a performance hit on Exchange while backing up.
2) Leverage snapshots the way Paul described,
which is all scriptable of course. However, you will need to post
a daily outage of a few minutes for Exchange backups. i.e. very tiny "backup
windows"

Re: Exchange and iSCSI
It's definitely possible, and some people do it. However,
you will
lose the ability to do supported backups via snapshots. So, for
backups, you'll either do your typical tape backup type solution, or
you will have to shut down Exchange and dismount the LUNs that the
information store and logs live on, then snapshot, remount the LUNs
and start Exchange...
