Restoring Veeam backup of virtual WS2012R2 DC fails on boot

Post by riahc3 » Oct 21, 2015 10:08 am

Hello

Im using Veeam Backup & Replication 8 and I made a backup of a virtual machine (Hyper-V) that is a Windows Server 2012 R2 and it is my domain controller. Testing my backups (thank god), I installed Windows Server 2012 R2 on another PC and enabled Hyper-V on it as well. I installed Veeam Backup & Replication 8 on that PC as well and I tried to restore the backup. It restored but when I booted it up, it gives a BSOD 0xc00002e2

Obviously, this is worthless as I cannot restore my domain controller in a disaster emergency situation.

So, how do I make a V2V clone using Veeam?

John, have you enabled application-aware image processing in the corresponding backup job? Any chance the VM in question is configured for high availability?

So you're using VeeamZIP (free version) that doesn't have application-aware image processing logic. I would expect issues on domain controller restore in this case. However, looks like there're workarounds available.

There is no other domain controller.

Those steps are basically "start over from scratch". Its not a workaround.

The solution would be to switch Veeam B&R to full functionality mode and backup domain controller with application-aware image processing enabled, as it is always recommended to do.

My solution is powershell.

Turn off the VM

Do VeeamZIP

Turn on the VM

If DC downtime is applicable in your scenario, then you can do that as well.

[MERGED] problems after restoring Win2012 DC

Post by flubber » Dec 10, 2015 4:48 pm

Hello everybody,
I use veeam backup to obtain fast backup images of some vm (windows 7, windows 2012,...) that are running on a Win2012 HyperV host.
I have tried to restore the backup images on abother HyperV Win2012 Core, everything worked fine without issues with windows7 vm, windows 2012 server vm, etc....
The only (but BIG) problem I have is when restoring a windows 2012 server DOMAIN CONTROLLER, when you try to boot the vm the system is not able to boot completely and go into BSOD 0xc00002e2!
Browsing the internet I found several messages saying that this is due to the fact that Active Directry is very sensible about snaphots, image cloning, etc.....so I'm start to think that maybe veeam backup is NOT able to manage live backup of a domain controller efficiently....am I right or wrong?

Did somebody of you have the same problem or a similar situation?
How did you solve?
(consider that this is the ONLY DC, so unfortunaltey I cannot follow the demote / promote server roles way......)
thank in advance for your help

Re: Veeam B&R v5 recovery of a domain controller

Provided the DC was backed up with application-aware image processing enabled, there should not be any issues during restore. So I recommend contacting technical support with this.

mmmhhh....maybe I forgot to tell you one important thing :oops: : I'm currently using Veeam B&R 8.0 FREE edition.....

is this "application-aware image" function available only in the full edition?

maybe I can try to create the backup image when the vm is powered off to override this issue?

Right, free version doesn't have application-aware image processing logic. If DC downtime is acceptable, you can backup it this way.

ok I'll try to create a backup during the night, and than I will try to restore on the different hyper-V node to see if the 0xc000002e2 issue persists or not

thank you very much foggy!

I'd also recommend trying to backup with Veeam Endpoint Backup (VEB) instead of VeeamZip.

[MERGED] Application-aware processing on the free version

Post by vellum » Jan 24, 2017 12:06 am

Hello:

I'm using the free version of Veeam Backup & Replication 9.0 and I was reading through the link below about using the application-aware processing for DCs which seems to ensure AD is backed up properly.
https://www.veeam.com/blog/active-direc ... overy.html

However, the free version doesn't seem to have the application-aware processing feature though.
Have you guys used the free version to backup & restore DCs without issues?

You're right in saying that Free edition does not have Application Aware Image Processing functionality. Therefore, you need to power off DC VM prior to backing it up. Thanks.

Thanks. I see from the earlier post of using Veeam Endpoint Backup as another possible option. Would this work on a VM and the server also being a DC?

Yep, you can backup DC VM from the inside, using Veeam Endpoint Backup. However, DC will be fully supported only in forthcoming Veeam Agent for Windows 2.0 Server Edition. Thanks.

That's great news. Then for the restore (bare metal), if using the backup that was made inside the DC VM by Veeam agent for Windows 2.0, since it needs a target server to restore to when performing a restore, I should still regularly use Veeam Backup & Replication to backup the VM DC then use Veeam agent for Windows to restore over that VM DC, overwriting the existing volume?

You can perform bare-metal recovery to a computer even without any prior OS installation.
