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 < at > backup_server
Hopefully this helps.

Hi Weloki!
I've the same setup as yours and having the same problem, did you finally
found a solution?
I'm only able to do a full backup logging as root, and I don't want to do
that.... any help there?

On my server that I want backed up, I do not want to SSH into it as root,
so I've set up a special user that has an entry in /etc/sudoers to run
*only* the rdiff-backup command on the host with superuser privileges:
Cmnd_Alias RDIFFBACKUP = /usr/bin/rdiff-backup
rdiff-backup ALL = NOPASSWD: RDIFFBACKUP
...everything else about the user is normal. Now for any file that does
not have the chmod o+r (readable by "other") attribute I get this error
when trying to back it up:
ListError filename [Errno 13] Permission denied: '/path/to/filename'
The file permissions could look only like -------r-- and that would work,
in any other way, without the "r" for "other" I get the error. When I
perform backups logging in as root, backups are made fine.
