I'd choose to backup the Passive databases only, which is sufficient with a DAG setup and doesn't impact your resources on the active node, that's what I do.

But what if for a reason database switch from passive to active . Does DPM know where is the passive database ( mbx1 or mbx2 ) ? <br />

As per my experience of CA brighstor, the CA backup happens on the passive copy always. If it doesn't find passive one, it does backup for active copy.<br />
DPM behaves differently in this matter.

Hello , <br />
<br />
<br />
I have an Exchange 2013 CU3 installation with 2 MBX Servers and a database inside a DAG. I want to backup this database with DPM 2012 R2 . I have installed dpm agent in both mbx servers and in dpm when i create protection group in available members i see the DAG object. I expand DAG and then database name and in the tree i see both mbx servers. <br />
<br />
My question is if i must choose both mbx servers so to take both active and passive database backups . <br />
<br />
Thanks

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
