How many of you keep important or confidential information on your computer? I would guess that many of you have important or confidential information stored on your computer. Regardless of what it is, you do not want to lose the information you worked so hard to create. This is the reason you need to backup your computer files regularly.
A backup is a simply a copy of data from one medium to another which runs independently of the source medium. Backups include burning files to a CD-ROM, transfering files to another computer, or knowing that the files saved on your AFS space receive nightly backups.
If you have ever accidently deleted a file, suffered a computer virus, or ran into some other loss or corruption of data, you have most likely learned the value of a good backup. However, if you still think, "It wont happen to me," you'll be in for a shock when you lose that document you have been working on for the past six months. Trust us. We've seen it happen.
