When performing a Hyper-V VM backup (Windows Server 2016 or later versions), the following warning message is displayed on the backup client interface, or in the backup report:
| No. | Type | Timestamp | Log |
| * | ... | ... | ... |

For Microsoft Windows Server 2016 or later versions with AhsayOBM version 7.15.0.8 or above, the Resilient Change Tracking (RCT) feature is used to back up virtual machines.
Backup operations with the RCT require the virtual machine’s configuration version to be 8.0 or above.
To resolve the issue, upgrade the corresponding virtual machine’s configuration version in the Hyper-V Manager or the Update-VMVersion cmdlet.
Refer to the following article from Microsoft for instruction:
https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/deploy/Upgrade-virtual-machine-version-in-Hyper-V-on-Windows-or-Windows-Server
Note:
When you upgrade your Hyper-V environment to Windows Server 2016, the VM version of the virtual machines are not updated automatically. The Hyper-V administrator must update the VMs to the new version after the environment is upgraded to Windows Server 2016.
Ensure that the guest VM is offline before you update the VM version.
