I have installed and configured sbackup as explained in this Ubuntu Community Guide to SBackup. It is very convenient for me to launch the backup process the first time I shut down my PC each day. The idea would be that when I tell Ubuntu to shut my system down it launches the backup process if that is the first time in the day that my PC is halted. This way it doesn't mess with my workflow, just take a little more to shut down (no problem since I could then go away and let it finish by itself).
Any help with this?
