Veeam backup of Domain Controllers

Is it safe to backup and/or replicate a Domain Controller (Win2003 & Win2008) using Veeam Replication & Backup 7?

I am aware of the Application Aware option in Veeam. We can enable, but I can't find official documentation saying that that's enough.

How would the restore be done? let's say the Domain Controller host dies and I want to restore the Veeam backup from 24 hours ago. Just restoring it and starting it would start the Active Directory replication where it left up and continue replicating normally?

Thanks.

Solution 1:

I contacted Veeam directly. Their answer is:

There is no specific recommendations regarding domain controller backups, just make sure you have application-aware image processing enabled. You may find more information here: http://helpcenter.veeam.com/backup/70/vsphere/application_aware_processing.html

In case of restore, you may encounter the situation when for the first time DC boots in safe mode. It's an expected behavior, however, which is explained here: http://www.veeam.com/kb1277

So, I believe this means that the scenario is supported, and there are no special considerations to take apart from enabling the application-aware image processing, and make sure to know the DC's restore domain admin credentials (which one should know anyways).

Solution 2:

I personally have done it a lot of times. It's absolutely safe once you use VSS (application aware). The second KB which was recommended by Veeam is worth to be checked.
