If you used Backup and Restore to back up files or create system image backups in previous versions of Windows, your old backup is still available in Windows 10. In the search box next to Start on the taskbar, type control panel. Select Control Panel > Backup and Restore (Windows 7).
Use File History to back up to an external drive or network location. Select the Start button, select Settings > Update & security> Backup > Add a drive , and then choose an external drive or network location for your backups.
