Microsoft Hyper-V • Re: Wrong registry key kills B&R Application aware processing (#08074972)

Hi,
I also encountered this problem on a newly installed SQL server on Hyper-V. Older SQL servers are backed up fine.Unfortunately, I couldn't find this post, so I spent 2 days trying to figure it out. I found that the Hyper-V Volume Shadow Copy Requestor service (vmicvss) is not running and cannot be started.

Finally I found the key mentioned here in the registry, which had a different value than on the other servers. After editing the service started and everything works.

So I was now looking for what the VeeamHvVssGroupstemNetworkRestrictedRedirectionGuard value means and came across this post.
