And I added a script which I use in different places. However, I have
somehow broken the wiki by doing that -
http://rdiff-backup.solutionsfirst.com.au/index.php?ContribScripts
currently says "WikiFatalError - Stack bounds exceeded in
SetHTMLOutputMode". Sorry about that.

I do, too. But I don't understand them...

The script I wanted to add:

#!/bin/sh

# This script should be run on the backup-server, i.e. the 
# server storing the backup-data.
# It's assumed that ssh will be used to transport the 
# data, and that unattended ssh-login has been set up,
# see http://arctic.org/~dean/rdiff-backup/unattended.html

# The script may be put in a crontab so that backup is
# done every night.

# Version 1.0 (Thu Oct 30 2003) by Troels Arvin <address@hidden>.
# Use at your own risk.

# Room for improvement:
#  - backup the remote hosts in parallel
#  - use lock-files/semaphores to prevent concurrent
#    backup of the same host
#  - different options for the different hosts
