Hi Larry. I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.
That tutorial is for WIndows 8.1. Since then File Backup (backing up files automatically) and Image (backing up a system image to restore Windows if it becomes irreparable) have declined to the point we're expecting them to be discontinued soon.
Built-in File History, Windows Backup and Image Backup are having a lot of problems and may be phased out soon. For automated backup I'd use a better, more flexible app like free Macrium which just works.

In addition I'd have a secondary cloud backup that keeps your files safest from fire and theft:
You can drag 5gb for free into OneDrive app to store in the cloud where they are safe from fire and theft.
If you install Google Drive, you can use their new Backup to choose User folders (Documents, Pictures, etc.) to sync up to 15g for free to their cloud.
Or you can also drag or copy them to a USB external or flash drive.
Here's how to drag, copy or move large groups of files: https://www.pcworld.com/article/2086566/the-man...
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
