I have an Hyper-v host, running 2016 Nano server, and 2 guest VMs - one is Exchange server 2013 running on Server 2012 R2, the other one is a Server 2016 domain controller. I was able backup both VMs with application-aware enabled once, then after I changed a NIC on the host server and reboot, I'm getting the same error on both VMs "Unable to find Hyper-V hosts where VM 'd30c523b-5de1-477d-8453-c81238244a92'
. Contacted tech support, they said there's no VSS on the host and does not support "application-aware for Nano server' :https://helpcenter.veeam.com/docs/backup/hyperv/backup_2016.html?ver=95
So I reboot the host server again, with the "application-Aware" enabled, and no longer getting this error, the backup job was successful.
My question is, does Veeam 9.5 support "application-aware" on Nano server?
