"Germans would even ask for permission if going for a revolution"
Think more like a Frenchman ...
I for one would post the code and add the link, in case someone is looking for further explanations.
You could also add it to the debian wiki, but for that it would make sense to also write the explanations in English (though i have seen sites at the debian wiki which ain't got an English version, so you could do that too). I think there ain't such a page at wiki.debian.org, and it sure would be a step forward. As far i can tell your reputation will get a boost if you help with the debian wiki.
Perhaps ubuntuusers.de too (there sure already is a page with a backup-script, you could simply add yours)
