Hyper-V backup

Question

Hi guys, can I verify if the following is correct to perform a Hyper-V snapshot backup?

1) License required: Enterprise Client
2) Software&nbsp;required on&nbsp;Hyper-V host server:&nbsp;NBU Media Server
3) Policy type: FlashBackup-Windows

I tried configurating a policy for my hyper-v server, but receive&nbsp;a 'cannot connect on socket(25)' error while validating hyper-v machine name.

Any idea or advise please?

Thank you.

What about credentials? Did you checked them?

Where can&nbsp;I&nbsp;check the 'credentials' which you are referring to?

On the HyperV host server, do I really need to install the 'Media Server', or is 'Client' software able to do the job?

I tried on another Win2008 Hyper-V&nbsp;server, same error "validate hyper-v machine name failed" when configuring a new 'FlashBackup-Windows' policy.

What am I missing here??

nbu services should have admin rights on the hyper-v box.

very important thing to check that all your VM have corresponding DNS&nbsp;(forward and reverse lookup zones) entries configured. You should have entry for each vm, doesn't matter if you suppose to back it up or you don't.

NBU uses FQDN by default.

I managed to get it working, it was the VSXX&nbsp;access control causing authenication handshake failure.

I have to disable VSXX to get it working.

Does anyone know the correct configuration for VSXX for Hyper-V backup?
