As any computer user that has experienced a crash before knows, it is incredibly important to backup your PC. In the event that something goes awry with your PC, you do not want to risk losing all of your important files, whether you use your PC for work or strictly for personal use. The consequences of not backing up your PC can be dire. If you use it for work, you risk losing files that are integral pieces required for you to actually do your job. If you use it for play, then you risk losing precious family photos, a movie you love, or mp3s of an album that you hunted for for years.
