How do I completely remove "Backup" from my computer?

I somehow managed to enable "Backups" on my computer. Now I keep getting the message that my cloud storage space is finished.

How do I turn this absolute nonsense completely off? I have turned off backups in my Norton UI from under "Settings". But how do I clean up my cloud storage and remove the "Default Backup Set" from there? Frankly, this is all very annoying. I just want to go back to the way things were. I don't want to see these silly arrow icons on all my icons.

To stop the arrow icons on your file icons, from the classic interface click in Settings and uncheck the Backup Status Overlays under Quick Controls

Delete backup set and files from Cloud Backup
You can delete a backup set if it is no longer needed. You cannot delete a backup set if only one backup set is available. However, you can create a new backup set before you delete the old backup set.
