Veeam Replication of DC

Hi All,

I just wanted to get some opinions on Veeam Replication. I have a two server site, both servers are Hyper V hosts with two VM's on each, one VM on the first Host is a DC that holds all the FSMO roles, second server has a backup DC VM

Both of these DC's are gettings backed up with Veeam to a NAS, I also have the DC with the FSMO roles replicating to the other Hyper V Host.

Is it best practice to have this FSMO holding DC replicated which i could fail over with Veeam if i loose it, or is it better to just have the backup, if I lose the FSMO DC, rather seize the FSMO roles on the backup DC and build a new DC, transfer roles back etc.

The replication job of the FSMO DC is working perfect with Application Aware enabled.

Veeam's articles kinda suggest its ok but other forums suggest that FSMO transfer or Seize would be better.

I appreciate any advice or suggestions

First what is the Windows server? Because that is important when backup a DC. Using VM-Generation ID feature is only available in 2012 and 2016. Using VM-Generation ID will protect your DC in both options.

In my opinion you can use both options. Both will work.

But your should keep in mind these rules from Microsoft:

If a role has to be moved to a different domain controller, and the current role holder is online and available, you should transfer (not seize) the role to the new domain controller. FSMO roles should only be seized if the current role holder is not available. For more information, go to the following Microsoft website:

I have written an article regarding Backup Virtual DCs. In this article not using Veeam as an example, is Nakivo but the process is the same.
This is a good example: How to backup Virtual Domain Controllers

But I recommend that you have Global Catalog in both DCs. If you lose one with all the FMSO will be more difficult to restore.

Hope this can help.
