Dropbox is a great service for synchronizing data, and backup or even sharing.
I use it at work to backup all my projects so i can access them from home or whatever..
there are other free backup services like live mesh, but i think dropbox is the best
if you register through my link, you'll get 2.25 GB instead of 2 GB :wink:
you can even use it to host javascripts, ico files (especially for bloggers )
