XenServer - VM Backup Options NAUBackup vs Veeam
-
So In having a discussion on a separate forum the question was raised that Snapshots are a bad practice for Domain controllers. Here's the original discussion
Yet using Veeam to backup your vDC's is "perfectly acceptable".
Now with NAUBackup or Veeam both backups are stored off host/pool. And as far as I can tell, create a full backup of the VM at it's current state.
So what specifically is acceptable with Veeam, that is not acceptable with NAUBackup? Why is one corporate tool an acceptable solution, if both result in the same output?
Do they result in the same output? What specifically is different between the solutions, besides the fact that one is a corporate solution, especially if the end result is the same?
And to clarify, we aren't using NAUBackup on any of our DC's. I'm just looking for clarification.

Databases in general. DCs are not special.

Taking a snapshot of a DC is fine. Using one tool or the other makes no difference. The thing that matters is that you can't restore from a snapshot unless you've lost all DCs. If any are left still working, you rebuild and let them sync up.

So in regards to your topic Burned by Eschewing Best Practices wouldn't Gary be burning him self?

Can AD not handle old copies? I was under the impression that it could.

Unless he lost every DC in his environment. *
In which case a DC Snapshot is the last resort. Which is understandable. I have a feeling that he (and possibly others) have a large misunderstanding on what the Snapshot and Backup tools are for.

The latest version can, but only the latest. It's a new feature that MS just added.

One problem is you used the terms snapshot and backup in the same idea.
People have been told snapshots are not backups and do not understand that all the backup tools rely on snapshots to work.

Better to refer to it as an image-based backup or a hypervisor platform backup. Those that understand still know it is a snapshot, but people will think about it as a backup not as a snapshot.

Here's a follow up (and separate topic) so we aren't stealing the OP's topic.

This is my understanding as well. As long as you only have 2012 (and maybe it's only 2012R2) DCs then you can restore backup of a DC without any issues (according to the documentation
) -
