we are planning to migrate from an Exchange 2010 single server setup to a two server active/passive DAG environment (Exchange 2010). Both on vSphere 5.1 hosts. We are in touch with an engineer of our service partner for Exchange and he want to know if Veeam Backup & Replication can process an incremental backup of the passive node?
I read already the KB article https://www.veeam.com/blog/how-to-backup-exchange-database-availability-groups-dags-with-veeam-backup-replication.html
and learned that Veeam can do a backup of the passive node but I didn't found any hint if it works with incremental backups on the passive node also.
I'm not aware how a DAG works in detail right now but please allow the question if the behavior of incremental backups changed in a DAG environment compared to a single server setup? Normally an incremental backup deals with the transaction logs and should be no problem if the copy of the database is in use or not but this question let me took notice that this behavior could be changed in a DAG environment, especially on the passive node.
We have a meeting today with the service partner and it would be great if I could answer his question.
Thanks in advance & Bye Tom
