Yes, I'd like such a system. But why limit it to backups?

Do you have working code already?

Speaking of backups, are you satisfied with duplicity? What else did you try? what made you choose it over competition? Would you recommend it or try something else?

I'd have thought you'd have wanted to have a break at Xmas, but I guess building a backup system is as good as break to you, innit? :P :) Good luck - but do make sure you have some kind of a rest, at least! unlike those of us who'll have to swot..</p> Whew!
