Lifehacker has a great article on setting up your computer to automatically back up your hard drives, even uploading them to an FTP site for off-site backup.
Don’t expect yourself to remember to back up your data, or stack your closet full of burned CD’s or DVD’s. Today we’re going to set up automated nightly, weekly, monthly local and off-site backups for your PC using free software. Once you get this up and running, you’ll never have to worry about losing data again.
