Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Amazon S3 Glacier (Glacier) is a storage solution for "cold data."

Glacier is an extremely low-cost storage service that provides secure, durable, and easy-to-use storage for data backup and archival. With Glacier, customers can store their data cost effectively for months, years, or decades. Glacier also enables customers to offload the administrative burdens of operating and scaling storage to AWS, so they don't have to worry about capacity planning, hardware provisioning, data replication, hardware failure and recovery, or time-consuming hardware migrations.

Glacier is a great storage choice when low storage cost is paramount and your data is rarely retrieved. If your application requires fast or frequent access to your data, consider using Amazon S3. For more information, see Amazon Simple Storage Service (Amazon S3).

You can store any kind of data in any format. There is no maximum limit on the total amount of data you can store in Glacier.

If you are a first-time user of Glacier, we recommend that you begin by reading the following sections in the Amazon S3 Glacier Developer Guide:

  • What is Amazon S3 Glacier - This section of the Developer Guide describes the underlying data model, the operations it supports, and the AWS SDKs that you can use to interact with the service.

  • Getting Started with Amazon S3 Glacier - The Getting Started section walks you through the process of creating a vault, uploading archives, creating jobs to download archives, retrieving the job output, and deleting archives.

Sending a Request Using Glacier

var glacier = new AWS.Glacier();
glacier.abortMultipartUpload(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the Glacier object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var glacier = new AWS.Glacier({apiVersion: '2012-06-01'});

You can also set the API version globally in AWS.config.apiVersions using the glacier service identifier:

AWS.config.apiVersions = {
  glacier: '2012-06-01',
  // other service API versions
};

var glacier = new AWS.Glacier();

Version:

  • 2012-06-01

Method Details

abortMultipartUpload(params = {}, callback) ⇒ AWS.Request

This operation aborts a multipart upload identified by the upload ID.

After the Abort Multipart Upload request succeeds, you cannot upload any more parts to the multipart upload or complete the multipart upload. Aborting a completed upload fails. However, aborting an already-aborted upload will succeed, for a short time. For more information about uploading a part and completing a multipart upload, see UploadMultipartPart and CompleteMultipartUpload.

This operation is idempotent.

An AWS account has full permission to perform all operations (actions). However, AWS Identity and Access Management (IAM) users don't have any permissions by default. You must grant them explicit permission to perform specific actions. For more information, see Access Control Using AWS Identity and Access Management (IAM).

For conceptual information and underlying REST API, see Working with Archives in Amazon S3 Glacier and Abort Multipart Upload in the Amazon Glacier Developer Guide.

  uploadId: "19gaRezEXAMPLES6Ry5YYdqthHOC_kGRCT03L9yetr220UmPtBYKk-OssZtLqyFu7sY1_lR7vgFuJV6NtcV5zpsJ", 
  vaultName: "my-vault"
 };
 glacier.abortMultipartUpload(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
 });

Calling the abortMultipartUpload operation

var params = {
  accountId: 'STRING_VALUE', /* required */
  uploadId: 'STRING_VALUE', /* required */
  vaultName: 'STRING_VALUE' /* required */
};
glacier.abortMultipartUpload(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • accountId — (String)

      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.

    • vaultName — (String)

      The name of the vault.

    • uploadId — (String)

      The upload ID of the multipart upload to delete.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

abortVaultLock(params = {}, callback) ⇒ AWS.Request

This operation aborts the vault locking process if the vault lock is not in the Locked state. If the vault lock is in the Locked state when this operation is requested, the operation returns an AccessDeniedException error. Aborting the vault locking process removes the vault lock policy from the specified vault.

A vault lock is put into the InProgress state by calling InitiateVaultLock. A vault lock is put into the Locked state by calling CompleteVaultLock. You can get the state of a vault lock by calling GetVaultLock. For more information about the vault locking process, see Amazon Glacier Vault Lock. For more information about vault lock policies, see Amazon Glacier Access Control with Vault Lock Policies.

This operation is idempotent. You can successfully invoke this operation multiple times, if the vault lock is in the InProgress state or if there is no policy associated with the vault.

      the de-serialized data returned from the request. Set to null if a request error occurs.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

completeMultipartUpload(params = {}, callback) ⇒ AWS.Request

You call this operation to inform Amazon S3 Glacier (Glacier) that all the archive parts have been uploaded and that Glacier can now assemble the archive from the uploaded parts. After assembling and saving the archive to the vault, Glacier returns the URI path of the newly created archive resource. Using the URI path, you can then access the archive. After you upload an archive, you should save the archive ID returned to retrieve the archive at a later point. You can also get the vault inventory to obtain a list of archive IDs in a vault. For more information, see InitiateJob.

In the request, you must include the computed SHA256 tree hash of the entire archive you have uploaded. For information about computing a SHA256 tree hash, see Computing Checksums. On the server side, Glacier also constructs the SHA256 tree hash of the assembled archive. If the values match, Glacier saves the archive to the vault; otherwise, it returns an error, and the operation fails. The ListParts operation returns a list of parts uploaded for a specific multipart upload. It includes checksum information for each uploaded part that can be used to debug a bad checksum issue.

Additionally, Glacier also checks for any missing content ranges when assembling the archive, if missing content ranges are found, Glacier returns an error and the operation fails.

Complete Multipart Upload is an idempotent operation. After your first successful complete multipart upload, if you call the operation again within a short period, the operation will succeed and return the same archive ID. This is useful in the event you experience a network issue that causes an aborted connection or receive a 500 server error, in which case you can repeat your Complete Multipart Upload request and get the same archive ID without creating duplicate archives. Note, however, that after the multipart upload completes, you cannot call the List Parts operation and the multipart upload will not appear in List Multipart Uploads response, even if idempotent complete is possible.

An AWS account has full permission to perform all operations (actions). However, AWS Identity and Access Management (IAM) users don't have any permissions by default. You must grant them explicit permission to perform specific actions. For more information, see Access Control Using AWS Identity and Access Management (IAM).

completeVaultLock(params = {}, callback) ⇒ AWS.Request

This operation completes the vault locking process by transitioning the vault lock from the InProgress state to the Locked state, which causes the vault lock policy to become unchangeable. A vault lock is put into the InProgress state by calling InitiateVaultLock. You can obtain the state of the vault lock by calling GetVaultLock. For more information about the vault locking process, Amazon Glacier Vault Lock.

This operation is idempotent. This request is always successful if the vault lock is in the Locked state and the provided lock ID matches the lock ID originally used to lock the vault.

If an invalid lock ID is passed in the request when the vault lock is in the Locked state, the operation returns an AccessDeniedException error. If an invalid lock ID is passed in the request when the vault lock is in the InProgress state, the operation throws an InvalidParameter error.

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

computeChecksums(data) ⇒ map<linearHash:String,treeHash:String>

Computes the SHA-256 linear and tree hash checksums for a given block of Buffer data. Pass the tree hash of the computed checksums as the checksum input to the completeMultipartUpload() when performing a multi-part upload.

Examples:

Calculate checksum of 5.5MB data chunk

var glacier = new AWS.Glacier();
var data = Buffer.alloc(5.5 * 1024 * 1024);
data.fill('0'); // fill with zeros
var results = glacier.computeChecksums(data);
// Result: { linearHash: '68aff0c5a9...', treeHash: '154e26c78f...' }

Parameters:

  • data (Buffer, String) —

    data to calculate the checksum for

Returns:
