Resilience in Amazon Glacier - Amazon Glacier
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

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, Amazon recommends the Amazon S3 Glacier storage classes, which deliver a superior customer experience with S3 bucket-based APIs, full Amazon Web Services Region availability, lower costs, and Amazon service integration. If you want enhanced capabilities, consider migrating to Amazon S3 Glacier storage classes by using our Amazon Solutions Guidance for transferring data from Amazon Glacier vaults to Amazon S3 Glacier storage classes.

Resilience in Amazon Glacier

The Amazon global infrastructure is built around Regions and Availability Zones. Amazon Regions provide multiple, physically separated and isolated Availability Zones that are connected with low latency, high throughput, and highly redundant networking. These Availability Zones offer you an effective way to design and operate applications and databases. They are more highly available, fault tolerant, and scalable than traditional single data center infrastructures or multi-data center infrastructures. Amazon Glacier redundantly stores data in multiple devices spanning a minimum of three Availability Zones. To increase durability, Amazon Glacier synchronously stores your data across multiple AZs before confirming a successful upload.
