If you're new to archival storage in Amazon Simple Storage Service (Amazon S3), we recommend that you start by learning more about the S3 Glacier storage classes in Amazon S3, S3 Glacier Instant Retrieval, S3 Glacier Flexible Retrieval, and S3 Glacier Deep Archive. For more information, see S3 Glacier storage classes and Storage classes for archiving objects in the Amazon S3 User Guide.

Uploading an Archive in a Single Operation Using the AWS SDK for Java

Both the high-level and low-level APIs provided by the Amazon SDK for Java provide a method to upload an archive.

Uploading an Archive Using the High-Level API of the AWS SDK for Java

The ArchiveTransferManager class of the high-level API provides the upload method, which you can use to upload an archive to a vault.

Note

You can use the upload method to upload small or large archives. Depending on the archive size you are uploading, this method determines whether to upload it in a single operation or use the multipart upload API to upload the archive in parts.

Example: Uploading an Archive Using the High-Level API of the AWS SDK for Java

The following Java code example uploads an archive to a vault (examplevault) in the US West (Oregon) Region (us-west-2). For a list of supported AWS Regions and endpoints, see Accessing Amazon S3 Glacier.

For step-by-step instructions on how to run this example, see Running Java Examples for Amazon S3 Glacier Using Eclipse. You need to update the code as shown with the name of the vault you want to upload to and the name of the file you want to upload.

import java.io.File;
import java.io.IOException;
import java.util.Date;

import com.amazonaws.auth.profile.ProfileCredentialsProvider;
import com.amazonaws.services.glacier.AmazonGlacierClient;
import com.amazonaws.services.glacier.transfer.ArchiveTransferManager;
import com.amazonaws.services.glacier.transfer.UploadResult;


public class ArchiveUploadHighLevel {
    public static String vaultName = "*** provide vault name ***";
    public static String archiveToUpload = "*** provide name of file to upload ***";
    
    public static AmazonGlacierClient client;
    
    public static void main(String[] args) throws IOException {
        
        
    	ProfileCredentialsProvider credentials = new ProfileCredentialsProvider();
    	
        client = new AmazonGlacierClient(credentials);
        client.setEndpoint("https://glacier.us-west-2.amazonaws.com/");

        try {
            ArchiveTransferManager atm = new ArchiveTransferManager(client, credentials);
            
            UploadResult result = atm.upload(vaultName, "my archive " + (new Date()), new File(archiveToUpload));
            System.out.println("Archive ID: " + result.getArchiveId());
            
        } catch (Exception e)
        {
            System.err.println(e);
        }
    }
}

Uploading an Archive in a Single Operation Using the Low-Level API of the AWS SDK for Java

The low-level API provides methods for all the archive operations. The following are the steps to upload an archive using the AWS SDK for Java.

  1. Create an instance of the AmazonGlacierClient class (the client).

    You need to specify an AWS Region where you want to upload the archive. All operations you perform using this client apply to that AWS Region.

  2. Provide request information by creating an instance of the UploadArchiveRequest class.

    In addition to the data you want to upload, you need to provide a checksum (SHA-256 tree hash) of the payload, the vault name, the content length of the data, and your account ID.

    If you don't provide an account ID, then the account ID associated with the credentials you provide to sign the request is assumed. For more information, see Using the AWS SDK for Java with Amazon S3 Glacier.

  3. Run the uploadArchive method by providing the request object as a parameter.

    In response, Amazon S3 Glacier (S3 Glacier) returns an archive ID of the newly uploaded archive.

The following Java code snippet illustrates the preceding steps. 

AmazonGlacierClient client;

UploadArchiveRequest request = new UploadArchiveRequest()
    .withVaultName("*** provide vault name ***")
    .withChecksum(checksum)
    .withBody(new ByteArrayInputStream(body))
    .withContentLength((long)body.length);

UploadArchiveResult uploadArchiveResult = client.uploadArchive(request);

System.out.println("Location (includes ArchiveID): " + uploadArchiveResult.getLocation());
