Prashanna,

    Please share the error with us. What is the NW version on this machine ?

Hi Prashana,

Try to re-install networker agent through administrator user or give full permission on nsr files from the user through which u have installed. Make sure while installation u select run as administrator option in installation wizard window.

Can you paste the exact error message here?

Also was this backup working fine earlier?

Have you tried backup as OS administrator?

As the probe (savefs) cannot run successfully, there is obviously no chance for any server-initiated program to succeed.

However, client-initiated backups can still work (as you see).

The origin could be a number of things (like firewall, name resoultion, access rights).

May I suggest that you run the savegroup command with "-D5" which should provide more detailled information:

     savegrp -D5 -c client -G 0100_Group_FS > filename.txt 2>&1

If necessary, you can even increase the debug level until you see the obvious problem.

Nw server 8.1 and client on theis host is Nw 7.6.3

As your client is a Windows 2008, i would suggest you to update the client to 8.1.1. Most of the backups issues related to VSS for windows 2008 are resolved in NW 8.1.1.
