Protect - Continuous Archiving (Lab) Option

I've just discovered the Continuous Archiving option in Protect, which is a Lab feature that I'd never noticed before (not sure if it's liked to EA). This seems to offer an answer to my concern over what happens if, for example, the burglar I've caught on video steals or destroys my NVR, as it now gives the option to do live archiving of selected cameras and event types to cloud services like OneDrive.

It seems to work in that I now have a UniFi folder in my OneDrive that contains video clips, but I'm not sure how practical it would be without some sort of storage quota on my OneDrive account before overwriting - it seems that I would have to manually keep and eye on it and delete older stuff every once in a while.

Has anyone had chance to implement a good solution here?
