Saved Games Using Only OneDrive. Is this normal?

I cleaned up a few documents in my OneDrive today. I did something unintentional because all of my saved games were gone. I google it, and one person said that saved games have a .save extension. So, I created a new game and the only thing with a .save extension, during the time I saved my new game, was saved to OneDrive\Documents\Electronic Arts\The Sims 4. I even searched my entire C:\ drive for all files created with today's date, but there were no other saves at that time. So, it appears the only place Sims is saving my games is on the OneDrive folder. I always thought OneDrive functioned as only a backup folder. Is this normal???

I should have searched for OneDrive and posted to that to a discussion already entered. I don't see the ability to delete my comment.
