Purchase Provisioned Capacity (POST provisioned-capacity) - Amazon S3 Glacier

This page is only for existing customers of the S3 Glacier service using Vaults and the original REST API from 2012.

If you're looking for archival storage solutions we suggest using the S3 Glacier storage classes in Amazon S3, S3 Glacier Instant Retrieval, S3 Glacier Flexible Retrieval, and S3 Glacier Deep Archive. To learn more about these storage options, see S3 Glacier storage classes and Long-term data storage using S3 Glacier storage classes in the Amazon S3 User Guide. These storage classes use the Amazon S3 API, are available in all regions, and can be managed within the Amazon S3 console. They offer features like Storage Cost Analysis, Storage Lens, advanced optional encryption features, and more.

Purchase Provisioned Capacity (POST provisioned-capacity)

This operation purchases a provisioned capacity unit for an AWS account.

A provisioned capacity unit lasts for one month starting at the date and time of purchase, which is the start date. The unit expires on the expiration date, which is exactly one month after the start date to the nearest second.

If the start date is on the 31st day of a month, the expiration date is the last day of the next month. For example, if the start date is August 31, the expiration date is September 30. If the start date is January 31, the expiration date is February 28.

Provisioned capacity helps ensure that your retrieval capacity for expedited retrievals is available when you need it. Each unit of capacity ensures that at least three expedited retrievals can be performed every five minutes and provides up to 150 MB/s of retrieval throughput. For more information about provisioned capacity, see Archive Retrieval Options.


There is a limit of two provisioned capacity units per AWS account.


To purchase provisioned capacity unit for an AWS account send an HTTP POST request to the provisioned-capacity URI.


POST /AccountId/provisioned-capacity HTTP/1.1 Host: glacier.Region.amazonaws.com Date: Date Authorization: SignatureValue Content-Length: Length x-amz-glacier-version: 2012-06-01


The AccountId value is the AWS account ID. This value must match the AWS account ID associated with the credentials used to sign the request. You can either specify an AWS account ID or optionally a single '-' (hyphen), in which case Amazon S3 Glacier uses the AWS account ID associated with the credentials used to sign the request. If you specify your account ID, do not include any hyphens ('-') in the ID.
