Make backups.

Make backups and store them safely. 
No matter what you do on a computer, whether itís for personal or business use, always make backup copies. Since you generally change and add information, make backup copies on a regular basis. Store these copies someplace safe and separate from the computer. When you do have a problem with the computer and lose information, having backup copies available to use for restoration can save countless hours.
