Cloud backup storage calculation
I apologize if this has been asked elsewhere, I wasn't able to find a good duplicate. I'm curious about the amount of storage I need to get if I want to purchase cloud backup storage.
Most of my backup data is fairly small, but one backup in particular can reach up to 800 GB or so of data. What I'm unsure of is the overlap while a new version is being written. For example, if I save a backup at 800 GB, and then I want to replace it with a new 800 GB backup the following evening, will that require 1TB of storage, or will it require 2 because it temporarily goes up to 1.6 TB while the first one exists and before the second one completes and overwrites/deletes the first one?
Or, to phrase the question in a different way if you prefer: is the maximum storage capacity defined as a hard cap even for temporary backup data, or is there some wiggle room with regards to data in the process of being deleted or that only goes over for a relatively short period of time?

Aha, thanks for the clarification and the welcome! That makes sense.
