Code:

dd if=/dev/mmbclk0 of=/media/usb/backup.img

Now you backup to your mounted usb drive.

@CurlyMo, I found this thread: http://forum.xbian.org/thread-884.html in which the user mk01 says that there could be problems doing that. Or am I missing something?
Is still my command line valid to backup or should I change something?
