I am using Backup Exec 12 - Rev. 1364. I have a failover single copy cluster (SCC) setup for Exchange 2007. I have two identical servers (active and passive), a separate server setup as the client server, and a storage array that houses the mailbox. The way I see it, it boils down to three access points (active cluster, client, or the mailbox on the storage array). Which access point should I be trying to access to backup the mailboxes and are the mailboxes the only thing I should be backing up.
