Back up your files
To make sure you don't lose the files that you create, modify, and store on your computer, you should back them up regularly. You can manually back up your files any time or set up automatic backups.
Open Backup and Restore Center by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Backup and Restore Center.
Click Back up files, and then follow the steps in the wizard.
If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Do not back up files to the same hard disk that Windows is installed on. For example, do not back up files to a recovery partition.
Always store media used for backups (external hard disks, DVDs, or CDs) in a secure place to prevent unauthorized people from having access to your files; a fireproof location separate from your computer is recommended. You might also consider encrypting the data on your backup.
