What is Backing up? • Computer backup is storing copies of your files on a medium other than your hard disk. The reason that we make computer backups is to protect against the event that something happens to damage our files so they are no longer usable. If we have backups of our files, then we can restore these files to our computer through our backups. Work School Music/Porn
Items to use for backing up. • CD-Rs are CD-ROMs that you can actually write onto, and hold up to 800 megabytes of storage. You can also use CD-RWs, which can be written onto more than once, unlike a CD-R. DVD burners are also becoming increasingly common, and a typical DVD-R can hold up to 4700 megabytes, or 4.7 gigabytes. • External USB hard drives are a great way for saving files. You can buy them at a computer store such as Best Buy and Circuit City. Check the packaging for the amount of files can be stored on it. • Also you can back up files on line or something as just emailing a document to yourself
