Hyper-V Off-host proxy requirement

[Yukinobu]

The Hyper-V role, which was listed as a requirement for the Hyper-V off-host proxy in V12, has been removed in V13.

Does this mean it's no longer necessary?
Also, the statement that it can only be assigned to physical machines has been removed. Does this mean that an improvement has been made so that the Hyper-V off-host proxy role can be assigned to a virtual machine without performance degradation?

Has no such improvement or change been made to the Hyper-V backup architecture, and is this due to a lack of documentation?
Which one should I believe?

Hello, Yukinobu,

Thank you for pointing that out.
I will clarify that internally and return with the answer.

Hello, Yukinobu,

I have clarified internally:
Veeam Data Platform v13, no longer requires HyperV off-host proxy to have the Hyper-V role installed, and as there is no need for nested Hyper-V anymore, the proxy does not need to be a physical machine for production use and can now be virtual machine now. Which was a specific limitation in the previous version.
Our documentation is accurate on that.
System Requirements
Off-Host Proxy

Off-host HV proxy is used to take the load off the source data processing overhead on HyperV node, including backup traffic itself, compression, encryption, etc.
So, it is now advised to use a VM in order to offload the possible additional processing overhead on a production host caused by backup procedures.
