Amazon Web Services introduced a new “Glacier” archival service priced at $0.01 per GB per month. 
Unlike Amazon’s S3 cloud storage service, which is optimized for rapid access, Glacier is designed for long-term, high-durability archiving with infrequent access. Each archive can contain up to 40 Terabytes of data and is encrypted with AES-256, Amazon will store the archive durably in an immutable form in multiple facilities. Retrieval requests are queued up and honored “at a somewhat leisurely pace” — within 3 to 5 hours. Up to 5% of the archive can be retrieved for free and there is a $0.01 per GB retrieval fee for the rest of the archive.
