Hi Duk, I set up a regular user's account for rdiff-backup on my backup server as well as a directory where I save the backed up files to. That directory has permissions for only rdiff-backup user and group (chmod -R rdiff-backup:rdiff-backup /dirname). On the servers that I want to be backed up I also created a user account for rdiff-backup, and in addition to the entry in /etc/sudoers, in the file at /rdiff-backup_home/.ssh/authorized_keys I put this on one line:
command="sudo rdiff-backup --server --restrict-read-only /",from="backup_server_IP_address",no-port-forwarding,no-X11-forwarding,no-pty ssh-rsa AAAAB3NzaC1...long SSH public key here... == rdiff-backup@backup_server Hopefully this helps.
