Hello,

  Please advice, i have an Exchange 2010 server with 2 DAG servers - DAG1 and DAG2 - backup with 2 DPM servers, one for DAG1 and one for DAG2 is it possible ?

Hi,

I confirmed with Exchange support team that DAGs could be backed up separately.

Meanwhile backup database is important if you need to recover both Exchange server settings and database. See:
