Upload Archive (POST archive) - 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.

Upload Archive (POST archive)


This operation adds an archive to a vault. For a successful upload, your data is durably persisted. In response, Amazon S3 Glacier (S3 Glacier) returns the archive ID in the x-amz-archive-id header of the response. You should save the archive ID returned so that you can access the archive later.

You must provide a SHA256 tree hash of the data you are uploading. For information about computing a SHA256 tree hash, see Computing Checksums.


The SHA256 tree hash is only required for the Upload Archive (POST archive) action when using the API. It is not required when using the AWS CLI.

When uploading an archive, you can optionally specify an archive description of up to 1,024 printable ASCII characters. S3 Glacier returns the archive description when you either retrieve the archive or get the vault inventory. S3 Glacier does not interpret the description in any way. An archive description does not need to be unique. You cannot use the description to retrieve or sort the archive list.

Except for the optional archive description, S3 Glacier does not support any additional metadata for the archives. The archive ID is an opaque sequence of characters from which you cannot infer any meaning about the archive. So you might maintain metadata about the archives on the client-side. For more information, see Working with Archives in Amazon S3 Glacier.

Archives are immutable. After you upload an archive, you cannot edit the archive or its description.


To upload an archive, you use the HTTP POST method and scope the request to the archives subresource of the vault in which you want to save the archive. The request must include the archive payload size, checksum (SHA256 tree hash), and can optionally include a description of the archive.


POST /AccountId/vaults/VaultName/archives Host: glacier.Region.amazonaws.com x-amz-glacier-version: 2012-06-01 Date: Date Authorization: SignatureValue x-amz-archive-description: Description x-amz-sha256-tree-hash: SHA256 tree hash x-amz-content-sha256: SHA256 linear hash Content-Length: Length <Request body.>


The AccountId value is the AWS account ID of the account that owns the vault. 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 use an account ID, do not include any hyphens ('-') in the ID.

Request Parameters

This implementation of the operation does not use request parameters.

Request Headers

This operation uses the following request headers, in addition to the request headers that are common to all operations. For more information about the common request headers, see Common Request Headers.

Name Description Required

The size of the object, in bytes. For more information, go to http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.13.

Type: Number

Default: None

Constraints: None


The optional description of the archive you are uploading. It can be a plain language description or some identifier you choose to assign. The description need not be unique across archives. When you retrieve a vault inventory (see Initiate Job (POST jobs)), it includes this description for each of the archives it returns in response.

Type: String

Default: None

Constraints: The description must be less than or equal to 1,024 characters. The allowable characters are 7-bit ASCII without control codes, specifically ASCII values 32—126 decimal or 0x20—0x7E hexadecimal.


The SHA256 checksum (a linear hash) of the payload. This is not the same value as you specify in the x-amz-sha256-tree-hash header.

Type: String

Default: None

Constraints: None


The user-computed checksum, SHA256 tree hash, of the payload. For information on computing the SHA256 tree hash, see Computing Checksums. If S3 Glacier computes a different checksum of the payload, it will reject the request.

Type: String

Default: None

Constraints: None


Request Body

The request body contains the data to upload.


In response, S3 Glacier durably stores the archive and returns a URI path to the archive ID.


HTTP/1.1 201 Created x-amzn-RequestId: x-amzn-RequestId Date: Date x-amz-sha256-tree-hash: ChecksumComputedByAmazonGlacier Location: Location x-amz-archive-id: ArchiveId

Response Headers

A successful response includes the following response headers, in addition to the response headers that are common to all operations. For more information about common response headers, see Common Response Headers.

Name Description

The relative URI path of the newly added archive resource.

Type: String


The ID of the archive. This value is also included as part of the Location header.

Type: String


The checksum of the archive computed by S3 Glacier.

Type: String

Response Body

This operation does not return a response body.
