I have 20TB of data that I would like to access about 1MB statistically per year (!!) only I don't know which of that 20TB its located. Sure there is AWS and then Glaciar but with my limited knowledge with AWS you need to spin a computer and then set the rules how those files are accessible and it already goes into tens or hundreds of bucks per month. Amazon Glaciar is too expensive to pull data out.

Perhaps I didn't do enough research. If you know company who allows me to cheaply store XX TB in cloud and charge me only per access to it, let me know please.
