Database Availability Groups (DAGs) are the primary fault-tolerant mechanism used for protecting mailbox databases in Exchange Server 2010 and 2013. DAGs allow for so much redundancy, in fact, that some people (both inside and outside of Microsoft) have expressed the idea that DAGs render Exchange Server backups obsolete, but that’s not strictly true. This article examines how backups work in a DAG environment, and whether or not you should be backing up your DAG members.
