If they can't afford a tape-drive, is there any possibility they could
afford to recover from a fire?
I'd be tempted to go for the 2 x USB drives option and swap them once a
week. If they have large HDDs in one or more PCs then you could share a
directory from them and back up nightly there too.
Your backup list is good, but if they're on limited resources they may
need to compromise. Can they archive emails from a year ago? Can they
archive old project files? Are there large numbers of duplicate word
docs they can live without instant access to?
