In previous versions of Windows, you could use Backup and Restore to back up your files or create and use a system image backup or repair disc. Windows 8.1 gives you choices about how you can recover your PC and back up your personal files.
If you’re having a problem with your PC, you can refresh Windows without losing your photos, music, videos, and other personal files. You can also start over by resetting it to factory settings. For more info, see How to refresh, reset, or restore your PC.
You can use File History to back up the files on your PC in the Documents, Music, Pictures, Videos, and Desktop folders. Over time, File History builds a history of your files. You'll first need to set up a File History drive and turn File History on. For more info, see Set up a drive for File History. If your original files are lost, damaged, or deleted, you can restore them. You can also browse and restore different versions of your files. For more info, see Restore files or folders using File History.
You can use System Image Backup like you did in previous verison of Windows.
Swipe in from the right edge of the screen, and then tap Search.(If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then click Search.)
Enter File History in the search box, tap or click File History, and then click System Image Backup.
