I have two virtual Exchange 2013 servers in a DAG configuration.
I am currently backing up both servers and have the active database server also performing the message level backups.
I had problems backing up the passive database server, until support pointed out that an INI file change was needed on the passive machine.. Ugh!
Now I can back up both servers, which raises a few questions...
Can I enable "Message Level" backups on both servers?
If so does the Barracuda Backup Appliance de-duplicate the messages between the two servers?
I switch the active server when I am performing software updates to avoid downtime. Each time I do so I am forced to modify the INI files accordingly and delete and recreate the "sources" and schedules to get a reliable backup. Backups fail if I don't do these two things with "Connection Lost" errors that are not really applicable.
However doing so places the retained data out of sync so to speak, as the Barracuda appliance now thinks it is dealing with a different and new machine. How can I avoid this?
I've been told by Tier 2 support that an upcoming firmware & agent update will fix this and remove the need for the configuration changes.
