Re: HYPER V Backup failed

Hi rajapandip@nbk.com,

   Can you please provide a screen shot of the tabs general and apps & modules from the client properties. Also, provide the out of the command nsrsnap_vss_save -v -? from the hyperV server.

Re: HYPER V Backup failed


Is this federated or non-federated backup?

Are you backing up CSV? Is a stand-alone or cluster Hyper-V?

If clustered Hyper-V environment please run the following command and share the output:

nsrsnap_vss_save -s networker server -v -?

Thank you,
