I am trying to get Veeam configured on our HyperV 2012 R2 cluster to use the Nimble hardware VSS provider on the hosts.
The VSS hardware provider is being called, but then get a Windows system event error 4020 stating:
Failed to create a snapshot. Reason: SOAP API error 1033.
This means the backup fails.
We are on firmware 2.3.14 and using NWT v 18.104.22.1687 on the HyperV hosts.
Does anyone know what could cause this error? I have installed KB2995388 update on the hosts (Which supersedes KB2966407)
