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

If you're looking for archival storage solutions, we recommend using the Amazon 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 Amazon Glacier storage classes.

Amazon Glacier (original standalone vault-based service) will no longer accept new customers starting December 15, 2025, with no impact to existing customers. Amazon Glacier is a standalone service with its own APIs that stores data in vaults and is distinct from Amazon S3 and the Amazon S3 Glacier storage classes. Your existing data will remain secure and accessible in Amazon Glacier indefinitely. No migration is required. For low-cost, long-term archival storage, AWS recommends the Amazon S3 Glacier storage classes, which deliver a superior customer experience with S3 bucket-based APIs, full AWS Region availability, lower costs, and AWS service integration. If you want enhanced capabilities, consider migrating to Amazon S3 Glacier storage classes by using our AWS Solutions Guidance for transferring data from Amazon Glacier vaults to Amazon S3 Glacier storage classes.

Using the AWS SDK for .NET with Amazon Glacier

The AWS SDK for .NET API is available in AWSSDK.dll. For information about downloading the AWS SDK for .NET, go to Sample Code Libraries. As described in Using the AWS SDKs with Amazon Glacier, the AWS SDK for .NET provides both the high-level and low-level APIs.

Note

The low-level API and high-level API provide thread-safe clients for accessing Amazon Glacier. As a best practice, your applications should create one client and reuse the client between threads.

Using the Low-Level API

The low-level AmazonGlacierClient class provides all the methods that map to the underlying REST operations of Amazon Glacier (Amazon Glacier) ( API Reference for Amazon Glacier). When calling any of these methods, you must create a corresponding request object and provide a response object in which the method can return a Amazon Glacier response to the operation.

For example, the AmazonGlacierClient class provides the CreateVault method to create a vault. This method maps to the underlying Create Vault REST operation (see Create Vault (PUT vault)). To use this method, you must create instances of the CreateVaultRequest and CreateVaultResponse classes to provide request information and receive a Amazon Glacier response as shown in the following C# code snippet:

AmazonGlacierClient client;
client = new AmazonGlacierClient(Amazon.RegionEndpoint.USEast1); 

CreateVaultRequest request = new CreateVaultRequest()
{
  AccountId = "-",
  VaultName = "*** Provide vault name ***"
};

CreateVaultResponse response = client.CreateVault(request);

All the low-level samples in the guide use this pattern.

Note

The preceding code segment specifies AccountId when creating the request. However, when using the AWS SDK for .NET, the AccountId in the request is optional, and therefore all the low-level examples in this guide don't set this value. The AccountId is the AWS account ID. This value must match the AWS account ID associated with the credentials used to sign the request. You can specify either the AWS account ID or optionally a '-', in which case Amazon Glacier uses the AWS account ID associated with the credentials used to sign the request. If you specify your Account ID, do not include hyphens in it. When using AWS SDK for .NET, if you don't provide the account ID, the library sets the account ID to '-'.

Using the High-Level API

To further simplify your application development, the AWS SDK for .NET provides the ArchiveTransferManager class that implements a higher-level abstraction for some of the methods in the low-level API. It provides useful methods, such as Upload and Download, for the archive operations.

For example, the following C# code snippet uses the Upload high-level method to upload an archive. 

string vaultName = "examplevault";
string archiveToUpload = "c:\folder\exampleArchive.zip";

var manager = new ArchiveTransferManager(Amazon.RegionEndpoint.USEast1);
string archiveId = manager.Upload(vaultName, "archive description", archiveToUpload).ArchiveId;

Note that any operations you perform apply to the AWS Region you specified when creating the ArchiveTransferManager object. All the high-level examples in this guide use this pattern.

Note

The high-level ArchiveTransferManager class still needs the low-level AmazonGlacierClient client, which you can pass either explicitly or the ArchiveTransferManager creates the client.

Running Code Examples

The easiest way to get started with the .NET code examples is to install the AWS SDK for .NET. For more information, go to Amazon SDK for .NET.

The following procedure outlines steps for you to test the code examples provided in this guide.

General Process of Creating .NET Code Examples (Using Visual Studio)

1

Create a credentials profile for your AWS credentials as described in the Amazon SDK for .NET topic Configuring AWS credentials.

2

Create a new Visual Studio project using the AWS Empty Project template.

3

Replace the code in the project file, Program.cs, with the code in the section you are reading.

4

Run the code. Verify that the object is created using the AWS Management Console. For more information about AWS Management Console, go to http://aws.amazon.com/console/.

Setting the Endpoint

By default, the AWS SDK for .NET sets the endpoint to the US West (Oregon) Region (https://glacier.us-west-2.amazonaws.com). You can set the endpoint to other AWS Regions as shown in the following C# snippets.

The following snippet shows how to set the endpoint to the US West (Oregon) Region (us-west-2) in the low-level API.

AmazonGlacierClient client = new AmazonGlacierClient(Amazon.RegionEndpoint.USWest2);

The following snippet shows how to set the endpoint to the US West (Oregon) Region in the high-level API.

var manager = new ArchiveTransferManager(Amazon.RegionEndpoint.USWest2);
