In Pictures: 10 Cloud storage and backup services ...
Unlike most of the services on the list, Amazon Glacier is a niche storage service designed to offer durable and low-cost storage solely to meet data archival and backup needs. Modeled after Amazon's Simple Storage Service (S3) offering, Amazon Glacier differs in that it's optimized for data that is infrequently accessed, making Glacier suitable only for data where retrieval time of a few hours is acceptable. The cost of storing data at Amazon Glacier is $0.01 for 1GB per month, which works out to about $10 per month for 1TB. Do note that this excludes data transfer charges incurred when uploading and retrieving data.
