Get Data Retrieval Policy (GET policy) - Amazon S3 Glacier
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

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.

Get Data Retrieval Policy (GET policy)

Description

This operation returns the current data retrieval policy for the Amazon Web Services account and Amazon Region specified in the GET request. For more information about data retrieval policies, see S3 Glacier Data Retrieval Policies.

Requests

To return the current data retrieval policy, send an HTTP GET request to the data retrieval policy URI as shown in the following syntax example.

Syntax

GET /AccountId/policies/data-retrieval HTTP/1.1 Host: glacier.Region.amazonaws.com.cn Date: Date Authorization: SignatureValue x-amz-glacier-version: 2012-06-01

Note

The AccountId value is the Amazon Web Services account ID. This value must match the Amazon Web Services account ID associated with the credentials used to sign the request. You can either specify an Amazon Web Services account ID or optionally a single '-' (hyphen), in which case Amazon S3 Glacier uses the Amazon Web Services 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.

Response Body

The response body contains the following JSON fields.

BytesPerHour

The maximum number of bytes that can be retrieved in an hour.

This field will be present only if the value of the Strategy field is BytesPerHour.

Type: Number

Rules

The policy rule. Although this is a list type, currently there will be only one rule, which contains a Strategy field and optionally a BytesPerHour field.

Type: Array

Strategy

The type of data retrieval policy.

Type: String

Valid values: BytesPerHour|FreeTier|None. BytesPerHour is equivalent to selecting Max Retrieval Rate in the console. FreeTier is equivalent to selecting Free Tier Only in the console. None is equivalent to selecting No Retrieval Policy in the console. For more information about selecting data retrieval policies in the console, see S3 Glacier Data Retrieval Policies.
