I am running an Exchange 2010 SP3 UR6 2 member DAG. DAG member 1 has 4 active databases and DAG member 2 has the passive copy. I use DPM 2012 (not R2) to protect the DAG, we do an Express Full each night and one db gets a "Full" backup and
the other gets a "Copy" backup. I have had no issues. I just added a 3rd DAG member, it will hold the same 4 copies. Of course, at any point it could hold some or all of the Active db's. The question I have is do I need to back the databases up on
that new 3rd DAG member? It doesn't seem like I would need to since I am already backing up 2 copies of each db.
