Link: Dropbox
What is the easiest way to backup and sync files across multiple platforms? The answer is Dropbox. This amazing web service, recently opened to public beta is awesome! As a student this resource is so valuable. I take my macbook to classes and take notes, write papers, etc. I want to make absolutely sure that all of my time-consuming research is secure and redundantly backed up in several locations. Dropbox is a unique file backup service in that it will take a directory of your choosing, upload those files to its own server, then distribute those files immediately to all of your designated machines. A small client application configured with your dropbox account credentials aids in the folder selection, file upload, and syncing processes.
A basic account comes with 2GB of FREE storage, which can be upgraded if you want a payed account.
