How is Geo Redundant Storage charged on Microsoft Azure?
===

SO I have been using the azure 3 month trial, to test out whether I want to use Microsoft Azure to host a project I am working on, however I have been very confused as I have run out of "Geo Redundant Storage" in the first month and I don't really understand why.

I have read this: https://www.windowsazure.com/en-us/pricing/details/ and the only thing I can make of it, is that it takes an average of how much storage you are using across a month, eg as long as I am using less then 35gb (for a 35gb limit) on average of storage space I am in the clear. 

So under my Azure Subscriptsions 'STORAGE (GB/MONTH) - GEO REDUNDANT' it says '101.027% of 35 GB/month' (so I have reached my cap).

But I don't understand why this would be happening, all I have is a simple server with a nodejs web application and a redis database (pretty much an empty at the moment), all running on an ubuntu VM, and as I can't login and check storage now because it is disabled, but I am pretty sure it is nowhere ***even near*** 35gb total storage and never has been?

I am hoping someone can explain how the azure storage is charged or if I have missed something silly?
