DPM 2012 R2 and Exchange 2013 CU3 DAG Backup

Hello ,


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.

My question is if i must choose both mbx servers so to take both active and passive database backups .

Thanks

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 ) ?

DPM is database role agnostic so no, it doesn't know and doesn't care where the passive database is, it doesn't matter what database it will backup, it can be used to protect a server that hosts a collection of active or passive mailbox databases...

But if you set it up, you can choose the passive databases...

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.
DPM behaves differently in this matter.
