Re: It's cheap as chips
Well, it's sort of cheap.
I've just had a good look around their site (and the AWS blog) and have found out a few things.
First, the data is stored redundantly (specifically can cope with failure of two stores simultaneously), and you can choose if you want it in the US, EU (Ireland, 10% more expensive) or APEC (Singapore, 12% more than the US).
You store data in 'archives'. Once you have uploaded an archive, you cannot change it (though you can add to it and delete the whole thing), you are charged for three months of storage as a minimum, and if you want to download it, you have to get the whole thing. So make sure you split your data up - each archive needs to be a file!
After requesting an 'archive' for download, you have to wait 3-5 hours before you can start to download it. You then have 24 hours to get it.
You need to know what you have stored. A list of the description (if you provide one), creation date and size of each archive is available, but is only updated once per day; if you need any more info you have to download the thing.
You can only download 5% of your stored data per month *pro rated daily* for free. After that, prices go up very fast! As an example, if you stored 1TB of data, and wanted to get the whole thing you would be charged about $369.80 (excluding taxes). (again, 10% more for EU, 12% more for APEC).
So, only good for archiving if you are pretty sure you're not going to want to get most of it back.
Working for the download charge:
Peak hourly retrieval for the month = 36 gigabyte per hour (80Mbps)
Billable peak hourly retrieval = Peak hourly retrieval (36) - Free retrieval hourly allowance (1.7GB) = 34.29
Retrieval fee = Billable peak hourly retrieval (34.29) x Hours in the month (720) x retrieval price ($0.01) = $246.92
Then you add the data download fee at $0.120 per GB. So 1024* 0.12 = $122.88. 122.88+246.92 = $369.8
