Add user to access incremental backups

Hi there,

I'm in a bit of trouble here. All my servers use the incremental backup system on cpanel to backup to a NFS share on another server, used only for that. This is all working without problems, however now i need to give access to the backupd data to a co-worker, so he can manually get data from the backup as needed.

Problem is, i couldn't find a way to give him access to these files! I tried creating a new linux user with the group "nobody", since thats the owner of the files created by the backup, but i still couldn't read then(they are readable by the group). Right now the only user that can read then is root, and i can't give him root access.

I also tried adding to the group "root" however i still couldn't read then.

Is there a way to do it? Thanks!
