Amazon Glacier Examples Using the AWS SDK for Go

Amazon Glacier is a secure, durable, and extremely low-cost cloud storage service for data archiving and long-term backup. The AWS SDK for Go examples can integrate Amazon Glacier into your applications. The examples assume you have already set up and configured the SDK (that is, you've imported all required packages and set your credentials and region). For more information, see Getting Started with the AWS SDK for Go and Configuring the AWS SDK for Go.

You can download complete versions of these example files from the aws-doc-sdk-examples repository on GitHub.

The Scenario

Amazon Glacier is a secure cloud storage service for data archiving and long-term backup. The service is optimized for infrequently accessed data where a retrieval time of several hours is suitable. These examples show you how to create a vault and upload an archive with Go. The methods used include:

Prerequisites

Create a Vault

The following example uses the Amazon GlacierCreateVault operation to create a vault named YOUR_VAULT_NAME.

Copy
svc := glacier.New(session.New(&aws.Config{Region: aws.String("us-west-2")})) _, err := svc.CreateVault(&glacier.CreateVaultInput{ VaultName: aws.String("YOUR_VAULT_NAME"), }) if err != nil { log.Println(err) return } log.Println("Created vault!")

Upload an Archive

The following example assumes you have a vault named YOUR_VAULT_NAME. It uses the Amazon GlacierUploadArchive operation to upload a single reader object as an entire archive. The AWS SDK for Go automatically computes the tree hash checksum for the data to be uploaded.

Copy
vaultName := "YOUR_VAULT_NAME" svc := glacier.New(session.New(&aws.Config{Region: aws.String("us-west-2")})) result, err := svc.UploadArchive(&glacier.UploadArchiveInput{ AccountId: aws.String("-"), VaultName: &vaultName, Body: bytes.NewReader(make([]byte, 2*1024*1024)), // 2 MB buffer }) if err != nil { log.Println("Error uploading archive.", err) return } log.Println("Uploaded to archive", *result.ArchiveId)
