In replay to your pulling down of programs from pronto, this is somthing that installers ask for. How would you feel if you spent 40 hours doing a file with custom graphics and then, someone else came in to pull your file from a remote and use all there file material for free...

Now , as for the backing up of your own data you should be doing this anyway, and it doesnt cost much to even put a copy on a USB stick while you are working on site just incase you spill liquid on your laptop or dropit. :)
