Amazon Glacier Retrieval Rates
Amazon AWS Glacier is a low-cost archive storage that enables you to back up data for the long-term at a price lower than Amazon S3. A typical use-case for AWS Glacier would be storage of data that does not require immediate restoration. Such data can include critical documents, SQL transaction logs, old video footage, etc. While Amazon S3 provides immediately accessible storage at higher prices, Glacier provides low-cost storage that can be accessed within hours.
When choosing to restore data from Amazon Glacier, you can select among the following three data retrieval modes:
This option is selected by default. It enables you to retrieve your data on time and on budget:
typical data retrieval time (3 to 5 hours);
a cost of $0.01 per GB, along with an extra charge of $0.05 for every 1,000 requests.
This is the best option for scheduled or non-urgent data retrieval. It features the lowest data retrieval speed at the lowest cost:
extended data retrieval time (5 to 12 hours);
a cost of $0.0025 per GB (with every 1000 requests amounting to $0.025).
This mode features the highest data retrieval speed at the highest price:
the shortest possible data retrieval time (1 to 5 minutes);
a cost of $0.03 per GB and $0.01 per request.
You can use any of the following Expedited data retrieval modes:
On-Demand requests are similar to EC2 On-Demand instances and are available most of the time.
Provisioned capacity guarantees that your retrieval capacity for Expedited retrievals is available even when demand for such retrievals is very high. Provisioned capacity units allow you to pay a fixed up-front fee to expedite retrievals from Amazon Glacier vaults for a given month.
When you select this option, all Expedited retrievals will automatically be served via your Provisioned capacity. Each unit of Provisioned capacity costs $100 per month and ensures that at least three expedited retrievals can be performed every five minutes with up to 150 MB/s of retrieval throughput. If you exceed that limit, expect errors on the part of Amazon.
