Summary

-If you're looking for archival storage solutions we suggest using the 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 [Glacier storage classes](https://aws.amazon.com/s3/storage-classes/glacier/) and [Long-term data storage using Glacier storage classes](https://docs.aws.amazon.com/AmazonS3/latest/userguide/glacier-storage-classes) in the _Amazon S3 User Guide_. These storage classes use the Amazon S3 API, are available in all regions, and can be managed within the Amazon S3 console. They offer features like Storage Cost Analysis, Storage Lens, advanced optional encryption features, and more.

+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](https://aws.amazon.com/s3/storage-classes/glacier/), 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](https://aws.amazon.com/solutions/guidance/data-transfer-from-amazon-s3-glacier-vaults-to-amazon-s3/).
