When configuring the protection group for an Exchange 2010 DAG all recommendations I've seen point to selecting the Exchange DB which selects all DAG members. When this is done say for a 2 node DAG there is a section to have one member be the Full Backup and the other to be the Copy Backup.
So once the protection begtins working I am seeing both DAG members in the protection group which have backed up the data. My question is:
Is DPM essentially backing up both members therefore I have 2 copies of the same data using up twice the space?
