Great news! In Windows 10 build 10130, Microsoft appears to have seen sense and brought back the perfectly functional Backup and Restore function that was removed in Windows 8.1. You can find it in the classic Control Panel under “Backup and Restore (Windows 7)”.
No longer do you have to use the File History feature. The Windows 7 version of Backup and Restore supports a schedule you control, all files on your hard disk, includes a System Image at the same time and will include your OneDrive files!
The cynic in me suspects this is only here for the benefit of Windows 7 users who have upgraded directly to 10, skipping Windows 8 and 8.1, rather than an admission that Windows was suddenly without a viable backup solution (which File History is not).
