Perhaps in your case but... NO... There are many more CORRECT reasons in this thread.
I CONTACTED NORTONS, BECAUSE THEIR SOFTWARE PLACED THE CHECK MARKS ON MY DESKTOP SOFTWARE, WHICH MEANT THE BACKUP WAS SUCCESSFUL. ALSO, NORTON'S HAS A WAY THAT YOU CAN DISABLE BACKUP NOTIFICATION. NO ISSUES FOR ME.
Yes... In your case it worked. But it can also be caused by OneDrive as well as many backup programs.

Kudos to you and your SHOUTING! I guess you made your point, even if it is on the tip of your head.
