You are welcome to put data on my machine, as I've a shiny new 250Gb disk only half full, and plenty of bandwidth. That way your data would be safe from a 1km dinosaur killer which could happily blat you, bibliogirl and wimble. Access through ssh. I'd use rsync from Unix, you can do
something similar from Windows, keeping the 2 directories in sync, only transferring changes.

I do this to alexmc's machine, so my photos are safe from a Norad strike.
