Get Data Retrieval Policy (GET policy)

Description

This operation returns the current data retrieval policy for the AWS account and AWS 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
Date: Date
Authorization: SignatureValue
x-amz-glacier-version: 2012-06-01

Note

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.

Response Headers

This operation uses only response headers that are common to most responses. For information about common response headers, see Common Response Headers.

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.
