Amazon claims 99.999999999% durability. https://aws.amazon.com/glacier/faqs/ https://aws.amazon.com/glacier/faqs/
2^40 * (1 - 99.999999999/100) = 10.99 bytes
- danieldk 14y agoIsn't it more bytes in practice? That's 88 bits, but they could be spread over different bytes, right? In other words: shouldn't you calculate the loss over the total number of bits?
- luser001 14y agoSorry, my comment above wasn't well thought out. Amazon's durability guarantee is on a per-object basis, not on a per-byte basis. I will post an article here after I research it thoroughly.
