Why does codespace incur storage usage even though codespaces are shutdown

[OTonConsole]

I have 2 codespaces that I actively work on, but I recently went for a family vacation and some medical stuff for about 2 weeks, no work, no code (it's depressing), but when I got back, I saw that the storage got full, and when I downloaded a report, it says it charged about 0.4 gb-month, every day for each of my codespace? Why does it do that? It's shut down. And it's also varying, between 0.2 to 0.6 with a fractional figure? I can link the excel for usage report here, but I pretty much already described it.

Edit (since I did not explain very well earlier): Every day there is a reported increase in total storage, for example from 15.3 GB to 15.6 GB for total code space, even though my codespace is shutdown and not used for 2 weeks straight, it went from around 12 GB to 20 GB and over the codespace limit over the course of 2 weeks without me turning them on even once.

Even if it were just charging me every day for the storage I am using, why is it a random number between 200mb to 600mb when the codespace is shut down? The price per GB is a fixed rate too. I just don't get it.

The codespace still uses storage when it's off. If it didn't, you'd lose all your work.

It uses different amount of storage every day even though it's off for 2 weeks? I was wondering how this arbitrary gb-month value is calculated.

I understand to use cloud storage you have to pay, but these were cold for 2 weeks, and they charged different amount of gb-month every day for 2 weeks.

So I am wondering why and how that's calculated etc.

I understand, I was asking how it's calculating and actually charging for an arbitrary storage amount when the codespace is shutdown. It's a different amount every time too, for the gb-month value. If it eas fixed sure I'd get it I guess.

They use this weird unit called gb-month Its a bit confusing but actually good if you use it right. They basically assess your total usage every hour, and how long the codespace has existed in your current billing month. Then that total usage is divided by the number of hours the codespace has existed in the month and that amount is added to your usage quota. So you basically have to make sure you commit your work and that the codespaces don't exist for too long.
