Guidance for Automated Restore and Copy for Amazon S3 Glacier Objects

Go to sample code

Overview

This Guidance enables you to leverage Amazon S3 Batch Operations with enhanced flexibility in manifest generation. You can either use an automated manifest generator that filters objects based on criteria like prefix, suffix, and last modified date, or manually upload a CSV manifest for precise control. The Guidance presents two architectural approaches: the first demonstrates how to request restoration of archived objects using S3 Batch Operations and perform copying through Batch Operations Invoke Lambda, while the second showcases an event-driven method for copying archived objects after being restored by S3 Batch Operations. These approaches provide efficient, scalable solutions for managing large-scale Amazon S3 operations, particularly when dealing with archived content.

How it works

Overview

This architecture shows how to request restoration of archived items listed in a CSV manifest. For details on how to automate the creation of the CSV manifest, open the Automated CSV Manifest Generator tab.

Automated CSV Manifest Generator

This architecture shows how to automate the creation of a CSV manifest using an AWS Step Functions workflow. For an overview of the full architecture, open the Overview tab.

Well-Architected Pillars

The architecture diagram above is an example of a Solution created with Well-Architected best practices in mind. To be fully Well-Architected, you should follow as many Well-Architected best practices as possible.

This Guidance can be re-deployed using the AWS CloudFormation template. The solution includes an SNS notification function that provides job status and failures.

Data stored in DynamoDB and Amazon S3 are protected by default through AWS encryption. By default, S3 buckets have access control lists (ACLs) disabled and public block access enabled.

Step Functions has retry and exponential back-off enabled to retry the Lambda functions it invokes. Step Functions states in the Guidance implement a retry and back-off mechanisms. Amazon S3 Batch Operations also retries Lambda service-related errors. Additionally, AWS Software Development Kits (SDKs) used in the Lambda functions have default retry and back-off configuration.

Amazon S3 Batch Operations is designed to manage large-scale operations. Lambda functions automatically scale to handle the number of concurrent invocations. You can enable provisioned capacity for DynamoDB which will reserve sufficient system resources to meet your requirements.

S3 Glacier provides multiple options for archive retrieval, including bulk retrieval, the lowest cost option that allows you to retrieve petabytes of data within 5-12 hours. S3 Glacier Flexible Retrieval provides free bulk retrieval for archived items that you’d want to retrieve infrequently, such as 1-2 times a year. Additionally, Amazon S3 Batch Operations allows you to manage billions of objects at scale without the need to provision costly and complex compute.

Read the Cost Optimization whitepaper

Amazon S3 Lifecycle rule is applied to the guidance S3 bucket to have objects expire after 180 days. The solution DynamoDB items are set to expire 60 days after restore and copy job completion. Automating expiration helps you avoid unnecessarily using storage resources for items that you no longer need.
