Has anyone seen this kind of configuration before?
I've encountered a configuration put in place for backing up Exchange 2010 that I need some clarification on.
The backup product is Symantec BE 2010 R3. The Exchange 2010 environment is; 3 CAS servers and 3 Mail server in a DAG.
The attachment shows the "backup server", Prod-back-02, is listed as a "mail server" within exchange. I've been told that this is done to facilitate the backing up of the exchange databases. I've never heard of such a thing before. I know you need to load the Exchange Console on the backup server and have the exchange agent on the backup server. I've always had success even at a granular, single piece of email, retore, based on the previous statement.
Can anyone shed any light, point to any Symantec documentation or even an urban myth as to why you would define your backup server as a mail host inside Exchange 2010?
Thanks for any input.
