We are in the progress of migrating to Exchange 2013 and are implementing a highly available design with several exchange servers.
We will be using two servers, one DAG and 4 databases. Two databases will be active on Server 1 and two active on Server 2.
Passive copies of the databases will be hosted on the other server in the pair for quick failover.
The issue we are seeing is that Veeam is not able to detect where the active or passive copy of the database is and only back that up.
For example, if we specify that Veeam should backup both servers, it will backup 4 databases on Server 1 and 4 databases on Server 2, thus requiring a much larger amount of backup media, or a good de-duplication setup.
Is there a way to avoid this and only backup either the active or the passive copies from each server, meaning that in normal operation only 2 databases from each server will be backed up?
Any advice would be very welcome.
