Since rdiff-backup does not like backup interruptions (and therefore is not usable on slow or unreliable connections) I rdiff to a local repository on the server (the server usually doesn't reboot) and rsync the entire repository to the remote destination.

My backup only runs when there is a internet connection. I use my laptop
at home most of the time. I have to find a way to check wether
rdiff-backup is running and to reboot after it shutdown. I can use htop
of course, but I am not sure if rdiff-backup is runnin also local on my

Maybe there is a more advanced way to do this?
You can test for running rdiff-backup locally thus:

[ -n "`ps -o pid --no-heading -C rdiff-backup`" ] && echo "running" ||
echo "not running"

and you can query remote server thus:

[ -n "`ssh user < at > remote.server "ps -o pid --no-heading -C rdiff-backup"
2>/dev/null`" ] && echo "running" || echo "not running"

Ah Thanks! So it should be possible to make some script which checks if
it's is running, if no, shutdown, if yes, wait 15 minuts and check again
etc... right?

yes you could write a bash script and put it as a job in your crontab to
run every 15 minutes, say...

My mirror backup server (not my primary) is updated from my primary by a
script which uses rdiff. The script runs on the primary and starts by
waking up the mirror server (over the internet), then runs rsync, then
after checking all is well, powers down the mirror. Works well with
rsync - as David pointed out earlier, it is not a good idea to run
rdiff-backup over an unstable connection.

I was thinking about a script on my laptop for shutdown my machine,
instead of running sudo shutdown -h now, run a script which only make
the laptop shutdown when rdiff-backup is not runnning.

I'm using fluxbox, so I'm used to shutdown my machine via terminal.

Here's a script 'auto-shutdown.sh' I use which shuts down a machine if
there is no ssh connection and certain other programs are not running:

if [ -z "`netstat -t|grep :ssh.*ESTABLISHED$`" ]; then
[ "`ps -A|grep -Ec "cp$|rsync$|mv$|rm$"`" = "0" ] && shutdown -h now
fi

add a line to /etc/crontab thus, to run the script hourly:
01 * * * * root /opt/auto-shutdown.sh

What do you mean by 'waking up the mirror server'?

Well our main backup is done by all our machines to a server on our LAN
using rdiff-backup - this I call the 'primary' backup server. Then each
night this primary machine runs a script which uses rsync to copy its
contents to an offsite machine, which therefore is maintained as a
'mirror' of the primary.

The mirror machine is normally switched off. To switch it on, the script
sends a 'magic packet' to the mirror machine, thus turning it on. Then
the script runs rsync, and when that is over, it shuts the mirror
machine down again.

In a simple case, you can use the wakonlan utility to wake the remote
machine: see http://gsd.di.uminho.pt/jpo/software/wakeonlan/. If it
isn't already available on your machine and you use Debian or Ubuntu you
can add it with apt-get I think. If the remote machine is behind another
router then waking it may be more complicated: I have a special script
to pass through Netgear DG834G router, for example (see
http://www.timedicer.co.uk/dg834g.)
