I have a backup server that uses rsync and pulls files from our other linux servers every night. I also want it to backup the /home/ folder of our mail server, so all of the users email is backed up as well. Of course each user has their own folder and are the owner of their respected folder. I have rsync configured to use sudo to log in with the user backup and pull the files. I was wondering what would be the best way to do this. Could I add the backup user to the wheel group to give him for administrative powers on the mail server so he would access all the folders? Any info would be appreciated. Thanks!
