Error: Could not run savefs: A required privilege is not held by the client

To isolate the problem you can run savegrp command in verbose mode (eg. savegrp -vvvvv -G ). You'll be able to see what files NetWorker is trying to backup when the error occurs and perhaps you'll get some more detailed error information.

I removed the "username" and "password" from the client setup and all is working now.
