The instructions on wiki.flimzy.com include a program called 'moo' that you could possibly run in a cronjob. The trick there is that after every 7th backup, a reboot is necessary (Because it mounts the newly-created backup image as an additional branch in the unionfs, and only 8 loopback devices can be mounted at a time).
If you don't mind an automatic reboot, you might be able to do something like this in a crontab: 1 1 * * * /usr/local/bin/moo 10 1 1 * * shutdown -r now That ought to do a snapshot every night, and reboot once a week. This method would likely need some fine-tuning. If you come up with a useable solution using my method on wiki.flimzy.com, please let me know so I can add them to my wiki--or create an account no my wiki and add your changes there yourself :) -- Jonathan On Tue, 2007-05-01 at 16:57 +0100, [EMAIL PROTECTED] wrote: > I have just tested several USB Live Distros, as per the instructions found at > > http://wiki.debian.org/DebianLive/Howto/USB > > How does a live USB Debian Linux created by the make-live from the new > live-helper package excatly make sure that changes are stored back to the USB > stick?
