Microsoft Hyper-V • Wrong registry key kills B&R Application aware processing (#03839416)

Hi everyone,
After upgrading to V13, we ran into issues with Application aware processing through VBR.

No Hyper-V production Snapshots could be generated on multiple machines spread over multiple customers (we're VCSP).

After a long search and trying everything we knew of this issue with previous versions, the solution came in form of a redid post from mazvazzeg (thank you!)

The issue were not missing open firewall ports, user rights, failed vss providers or anything like this.

Veeam changed the service entry for the Hyper V Volumeshadow requestor which prevented it from running at all:

The failed entry for the registry data undercontained in the ImagePath key which prevented the service from starting at all.
after changing it back to the valuethe service is starting again and everything is back to normal.

I'm waiting for Veeam to clarify, if this is a viable solution (at least it's a working one for me) and if there is a different way to fix this.

I'll keep you posted
Michael
