Earlier this week, Amazon announced a new service, called Amazon Glacier:
Amazon Glacier is an extremely low-cost storage service that provides secure and durable storage for data archiving and backup. In order to keep costs low, Amazon Glacier is optimized for data that is infrequently accessed and for which retrieval times of several hours are suitable. With Amazon Glacier, customers can reliably store large or small amounts of data for as little as $0.01 per gigabyte per month, a significant savings compared to on-premises solutions.
With such attractive prices, I'd like to consider using Amazon Glacier either in place of existing backup plans, or in addition to them. What should I be aware of before I start using Glacier, and how should I get started with sending my data?
