Support
The VSS Requester for Hyper-V supports the following Windows servers:
- Windows Server 2019 (Server Core and Server with Desktop Experience)
- Windows Server 2016 (Server Core and Server with Desktop Experience)
- Windows Server 2012 R2 with the October 2014 roll up
VMs running on SMB shares are not supported by the VSS Requester. Instead, use third-party applications along with the VSS Hardware Provider.
NOTE: The VSS Requester for Hyper-V supports partial successes and
failures. That is, situations where backups are successful for some VMs and not
successful for others. The Requester does not store information about which VMs
succeeded or failed. In these cases, extended error information about which VMs failed
and which ones succeeded is logged in a Windows application event log.
Snapshots will fail if the VM disks are in the root of the mount point.
