In Exchange 2003, I would create multiple  databases and set policy limits to keep those databases to a reasonable size for restore purposes. This resulted in having quite a few data stores.

Is the same logic  true for Exch 2010? Having many database sized to achieve a recovery time objective? Im currently running DAG too. Any database size best practice advice is welcome.

If you have 3 or more copies MS is saying you can go backupless and not run backups.

Size wise I would think about your network speed and how long it would take to Reseed your database (copy the whole database over the network). Microsoft is saying to keep databases under 2TB, but to be honest based on Reseed times I generally go for 250Gb database size. You might as well use that 100 DB limit right? ;-)

I agree with MegaNuk3. Secondly, bigger db's corruption risks are more as MS still unable to do any change at db. Still Jet db version.

Small db's will give better performance and let time for restore.

I agree with MegaNuk3. Secondly, bigger db's - corruption risks are more, as MS still unable to do any changes at db level. Still Jet db version.

I've heard that unlike Exch 2k3, you can keep Tlogs on the same Raid5 partition as the database.  True?

RAID1/10 is better for logs. Check more from below link
