Error code: 4201: Incorrect snapshot method configuration or snapshot method not compatible for protecting backup select Entries

Dear Guys 

I have an issue with one of my VM which is created on my 3 node Hyper-v cluster.

When I added VM, named VM111 in backup policy and finish the creation of that backup policy. 

Details are:-

Policy: NU -- Client: VM111.<domain name> (Hyper-V server: NU) --

           snapshot could not be created with Hyper-V_v2 method.

I got an error "Error code: 4201: Incorrect snapshot method configuration or snapshot method not compatible for protecting backup select Entries"

Please help me out to resolve this issue.

if possible please give step by step details

Thanks
Regards
