+1. Totally agree on the "not a good backup solution". But we both (obviously) know the difference between redundancy and backup. My poor mum does not. So in the end, that's a problem, and i'm not bashing dropbox either (paid account and all, use it all the time) : their position as it stands, is a bit like the "nobody can presumably be ignorant of the law" article in french civil code (which was suppressed a few years ago), a position no commercial service whose customers are volatile should take for granted.
