Dropbox is an application that creates a special Finder folder that automatically syncs online and between your computers. It allows you to both backup files and keep them up-to-date between systems.
Note: You must first sign up to use Dropbox.
The Dropbox application is available for OS X, Windows, and Linux. A video on the site explains more.
