The Amazon S3 Glacier storage classes provide you with long-term, secure, and durable storage options to optimally archive your data at the lowest cost. The Amazon S3 Glacier storage classes (https://aws.amazon.com/s3/storage-classes/glacier/instant-retrieval/, https://aws.amazon.com/s3/storage-classes/glacier/, and https://aws.amazon.com/s3/storage-classes/glacier/) are purpose-built for colder data, providing you with retrieval flexibility from milliseconds to days, in addition to the ability to store archive data for as low as $1 per terabyte per month.

Using S3 Batch Operations, you can restore archived data at scale by providing a manifest of objects to be retrieved and specifying a retrieval tier. With S3 Batch Operations, restores in the Standard retrieval tier now typically begin to return objects to you within minutes, down from 3–5 hours, so you can easily speed up your data restores from archive.

Getting Started with Faster Standard Retrievals from S3 Glacier Flexible Retrieval To restore archived data with this performance improvement, you can use S3 Batch Operations to perform both large- and small-scale batch operations on S3 objects.
