Amazon Glacier stores data for as little as $0.01 per gigabyte per month

Cheap cloud storage! 

Amazon Web Services

Dear Amazon Web Services Customer,

We are pleased to introduce a new storage option for Amazon S3 that enables you to utilize Amazon Glacier's extremely low-cost storage service for data archival. Amazon Glacier stores data for as little as $0.01 per gigabyte per month, and is optimized for data that is infrequently accessed and for which retrieval times of several hours are suitable. With the new Amazon Glacier storage option for Amazon S3, you can define rules to automatically archive sets of Amazon S3 objects to Amazon Glacier for even lower cost storage.

To store Amazon S3 objects using the Amazon Glacier storage option, you define archival rules for a set of objects in your Amazon S3 bucket, specifying a prefix and a time period. The prefix (e.g. "logs/") identifies the object(s) subject to the rule, and the time period specifies either the number of days from object creation date (e.g. 180 days) or the specified date after which the object(s) should be archived (e.g. June 1st 2013). Going forward, any Amazon S3 standard or Reduced Redundancy Storage objects past the specified time period and having names beginning with the specified prefix are then archived to Amazon Glacier. To restore Amazon S3 data stored using the Amazon Glacier option, you first initiate a restore job using the Amazon S3 API or the Amazon S3 Management Console. Restore jobs typically complete in 3 to 5 hours. Once the job is complete, you can access your data through an Amazon S3 GET request.

You can easily configure rules to archive your Amazon S3 objects to the new Amazon Glacier storage option by opening the Amazon S3 Management Console and following these simple steps:

  1. Select the Amazon S3 bucket containing the objects that you wish to archive to Amazon Glacier.
  2. Click on "Properties. Under the "Lifecycle" tab, click "Add rule."
  3. Enter an object prefix in the "Object prefix:" input box. This rule is now applicable to all objects with names that start with the specified prefix.
  4. Choose whether you want to archive your objects based on the age of a given object or based on a specified date. Click the "Add Transition" button and specify the age or date value. Click the "Save" button.

The Amazon Glacier storage option for Amazon S3 is currently available in the US-Standard, US-West (N. California), US-West (Oregon), EU-West (Ireland), and Asia Pacific (Japan) Regions. You can learn more by visiting the Amazon S3 Developer Guide or joining our Dec 12 webinar.
