Thanks, I would find it helpful if you could also explain that on your homepage. The statement "Amazon Glacier is designed to provide average annual durability of 99.999999999% for an archive" is quite clear and meaningful, but "Glacier is built for durability of 99.999999999%" just seems like a non-sensical marketing blurb.

If I got my math right, this means that they expect to lose on average about 10 bytes per stored terabyte per year. (Of course these losses, should they occur, would probably be not uniformely distributed).

Yeah, it is more like 1 file in a 100 billion gets lost.
