Back up your files
As our world becomes more digitized, the files we store on our computers are becoming increasingly more important. Instead of keeping handwritten letters in a shoebox, we correspond with family members using e-mail. If we use digital cameras, we often keep our photo albums on our computers.
Unfortunately, computers (and particularly the hard disk drives that hold your files) can fail. Your computer might run for a decade with no problems, or it could fail tomorrow -there's no way to tell. To make sure you don't lose important files if your computer stops working, you should back up your computer on a regular basis. The backup process copies your files to a safe place so that even if your computer fails, you won't lose them.
Choose backup storage
It doesn't make sense to back up your files to the hard disk drive inside your computer, because if your computer were to fail, you would also lose your backup. Instead, you should back up your files to an external hard disk drive or removable disk drive, such as a CD. If your computer does fail, you can then connect the external hard disk drive or use the CDs to restore your files to your new or repaired computer. (This article describes how to back up your files to an external hard disk drive, which is the easiest way to do a full backup of all your files. If you decide to use CDs, you'll need to choose which files to back up and then manually insert and remove CDs as
If you decide to get an external hard disk drive, choose one that is at least as large as the hard disk drive inside your computer. For example, if your computer has a 320 gigabyte (GB) hard disk drive, choose a 320 GB or larger external hard disk drive. Then connect the external hard disk drive to your computer. Make a note of the drive letter (such as E:, F:, or G:) assigned to your new hard disk drive.
