savegrp.exe command - Windows user account permissions?

Hi all,

Does anyone know what Windows permissions / policy settings are required for a specific user account to successfully run the savegrp.exe command without being a member of local administrator?

We use a script to backup certain servers due to other automated tasks that need to be run. Due to a recent security shakeup, the account that the script was run from was removed from the local administrator group on our NetWorker server, and the script now fails.

I have already tried the common sense stuff, like the Backup Operators group, and policy settings like "Log on as a batch job". The account already has administrator permissions inside NetWorker (have tested this with NetWorker User).

Below is the error I get when running the command as the specific account, without the admin rights. For testing purposes, the client in the group below triggers a local backup of C:\temp on the NetWorker server, and not backups of another client as we normally do. I have also tried using the runas command as well as logging in locally as the user account.

C:\Batch>savegrp AUPML_control-m_testgroup
05/09/07 12:33:51 savegrp: You are not authorized to run this command

The server is Win2003 and NetWorker version is 7.2.1.

Any assistance would be really appreciated. I can't find any mention of permissions in the savegrp documentation.
