worked like a charm with most of the servers and exchange (thanks for the post regarding disable service. It was actually enough to just disable topology service).
all servers was 2012.

My two 2012 R2 servers, fully patched, do not work yet, as they are not seeing that specific update yet.

Which is the latest rollup you have installed on those R2 servers?

had 1Gb left with updates after waiting a day :) after installing these, backups went just fine. so the issue is now the domain controller, as the original thread is related too.
We will wait for Microsoft here :)

by the way; storage spaces direct and 4X800 sata ssd + veeam gives almost 1Gbit in read speed during backup, pretty nice :)

Frank,

Glad to see that you are getting somewhere :-). Is the DC now the only one left (or is the TS also still a problem?)

the DC is the only one lef, the ts (2008 R2) was also much more happy after the KB3037623 install :)
have creatt a new domain controller (DC02) which runs on a small HP Microserver (200 USD) with free hyper-v 2012 r2 as host. Then we also have a 100% good backup of the dc for this customer as long as Microsoft has not released the update to solve the issue.

I find myself in the same position:

- Hyper-V host running Windows Server 2016
- VM running Windows Server 2012 R2 and Microsoft Exchange 2013 CU15
- Microsoft patch KB3037623 (referenced in prior posts) was already installed via Windows updates
- AAP still fails on backups

I was considering uninstall that patch and re-installing using the guidelines from the post by SALM (microsoft-hyper-v-f25/9-5-hyper-v-known-issues-t38927-45.html#p230347 , see below). What do folks think?
=======================================
My own Exchange runs on 2012 R2 and Exchange 2016 RTM and CU3.

I have confirmed that backups with AAP work for Exchange 2013 and 2016 (latest CU) on Windows Server 2012 R2, provided KB3037623 is installed on the guest OS (this KB updates integration services).

If the KB has not yet been installed, the vss will fail with the following error
Failed to create VM recovery checkpoint (mode: Veeam application-aware processing) Details: Job failed (''). Error code: '32768'. Failed to create VM recovery snapshot, VM ID '064dac1c-9652-4378-a69c-fa3429ca32a9'.
Retrying snapshot creation attempt (Failed to create production checkpoint.)


The KB is unable to be properly installed if Exchange is already installed (OS will hang on reboot)

The following service must be disabled prior to KB installation
AD Topology.
These services should be set to manual :
Microsoft Exchange Diagnostics
Microsoft Exchange Transport
Microsoft Filtering Management Service
Microsoft Exchange Search Host Controller

The services should be set to Automatic after successful KB installation.

I do not have any information on 2008 R2 Guest OS or previous versions of Exchange.

Thanks Frank!

Glad to hear that TS is solved also. Make sure that you are ready to seize the roles in a worst case scenario (I am assuming that DC01 still has the FISMO roles running) and you should be good to go for now. Obviously, just like you, I'm hoping MSFT to fix this as soon as possible!

What's the error you get ?
AAP should work if the guest OS is up to date.

To add to @salm's questions:

If you indeed have already installed KB3037623 on the VM and you still are getting issues as described in this thread then please log a support call. Let us also know what the exact error is you are getting. It might be something else

Thanks
Mike

I have already started a support call as I figured that was the next step. :)

I'm puzzled why KB3037623 would not be installed. The KB articles indicates this was released in March 2015.

I had a good support call with Veeam even though it hasn't resolved the issue yet. You can read the relevant verbiage from the ticket below. I am going to try using hyper-v quiescence and will let you know how that goes.

"Here's the recap for our WebEx today, and what information I'll need and what steps we're going to take to move forward on this case.

1) We confirmed that VSS is working as expected on both the guest and the host by initiating the same workflow on both sides independently of Veeam
2) We confirmed production checkpoints, which trigger VSS on the guest when taking the host level snapshot, were also working as expected
3) We confirmed the issue we're facing is a known Microsoft issue with backing up Windows 2012 R2 guests on Hyper-V 2016.
While the specific error we were facing (error 32770 creating production checkpoint) is known to affect DCs mainly, it appears we're facing the same issue and same behavior on your Exchange 2013 server. This has been acknowledge by Microsoft and will be fixed in a future update."

"As for our steps moving forward, we're going to reconfigure the job to utilize Hyper-V Quiescence on your Exchange guest. The manual production checkpoint executed properly and engaged VSS on the guest, and as far as our needs for Exchange go, this should be sufficient to make sure a transaction-safe backup is taken. This will not impact your ability to perform Exchange item restores as the Veeam Explorer for Exchange utilizes our file-level restore process to mount the Exchange database locally. As long as the Exchange database was properly prepared for hot backup, it'll be in a state that VEX can safely mount and utilize.

Here's the instructions on how to enable this:
https://helpcenter.veeam.com/docs/backu ... tml?ver=95

Make sure that VSS is disabled on the Exchange server under AAIP, as we reenabled it after correcting the DC settings to ignore the SQL server present. You'll still receive the warning on the DC about the SQL VSS writer not being present, but that's harmless. If you really want to eliminate the warning I believe there's a registry key to disable checking for SQL VSS writer presence, I'll do some digging to find it and let you know if I do."

My position now:

- Hyper-V host running Windows Server 2016
- VM running Windows Server 2012 R2 and Microsoft SQL Server 2014
- Microsoft patch KB3037623 (referenced in earlier posts) has been installed through Windows updates
- Veeam B&R 9.5 Update 1 running without any problems (after upgrate KB3037623) :D

Thanks all!

It seems the problem is the creation of production checkpoints.

Have you tried manually creating one ?

If it doesn't work, have you tried switching the VM back to pre-2016 checkpoint creation mode ?

Since I've been struggling as well to backup our DCs on Windows Server 2012 and Windows Server 2012 R2 on Hyper-V 2016, I thought to share my current workaround.
The mentioned KB3037623 has never been offered on any of the two servers ia Windows Updates, no matter what I did.
As of today, both servers are fully updated, having installed all optional updates as well and we are not using WSUS, so basically there is nothing more that could be installed apart from manual installations.

Initially found here the right comment: https://www.reddit.com/r/Veeam/comments ... ler_issue/

How I did it:
Reboot service EventSystem in the GUI, which will also restart its 3 to 4 dependent services
AFTER restarting the service EventSystem, only then restart also service VSS
It's important to note that you restart VSS as a last step, otherwise it won't work or if you did it the other way around you have to restart VSS once more, which also fixes the problem.
That's it, backups now run smoothly with AAIP enabled on both DCs.

Since this procedure has to be done on every VM reboot, it's rather handy to have a batch at hand that will be run on system boot as an automated task.
So I created a simple batch file with the following entries:
net stop BITS
net stop SENS
net stop NtFrs
net stop DFSR
net stop EventSystem
net start EventSystem
net start DFSR
net start NtFrs
net start SENS
net start BITS
net stop VSS
net start VSS

Afterwards setup a task that runs on every system boot. I added a 2 minutes delay, just in case the above service restarts could be executed to early, but I'm not sure on that and didn't spend the time to find out.
Hopefully that comes in handy to some of you.

Cheers Juri
