Backing-up Data

Irreplaceable files are ones you've created or purchased that you keep on your computer's hard drive and nowhere else. These can include your papers, work-related spreadsheets, artwork, music, e-mails, personal records, and anything else which you either created or purchased to place on your computer.

Installed software titles do not constitute irreplaceable files, but if you have saved documents or games, you will need to back those up as well.

Backup strategies will vary from person to person, and from computer to computer. Some computers have CD-RW devices which can burn files onto a CD. Some people prefer to use USB storage devices or even secondary hard drives to back up their critical files. Still others prefer to move their files over the network to another computer, or to a remote server. You should always have a strategy for backing up your critical and irreplaceable files.
