Hi, winfrey!
I use a backup system called "Clickfree" and I love it. You plug it into one of the USB ports on the computer (or computers) you want to back up, and it automatically backs up all of your files except your operating system and program files. It then categorizes all of your files (photos, text files, spreadsheets, music, etc.) for easy access, and it will even back up your browser settings, including bookmarks and favorites. You can back up files on more than one computer, and it stores them in separate files. After your initial backup, it then backs up only the files you alter or add. There is no software to install because it's built into the unit.
If you're interested, you can check it out at amazon.com to see which one would suit your needs.
