Hi Steve,
Windows System Backup is still included in Windows 8.
To launch the Windows Backup tool, open the Control Panel ->
Windows 7 File Recovery applet and click the "Set up Backup" button.
All of the old familiar options are there! Using Windows Backup, you can backup a
full system image or selected files & folders to an external drive or network location. You can also create a
system repair disc for repairing and restoring the system in the event that you encounter any boot issues.
About how to create system repair disk, please follow this guide:
