Amazon S3 Standard, S3 Standard-IA, S3 One Zone-IA, and Amazon Glacier, are all designed for 99.999999999% durability. Amazon S3 Standard, S3 Standard-IA and Amazon Glacier distribute data across a minimum of three geographically-separated Availability Zones to offer the highest level of resilience to AZ loss. S3 One Zone-IA saves cost by storing infrequently accessed data with lower resilience in a single Availability Zone. Amazon S3 Standard-IA is a good choice for long-term storage of master data that is infrequently accessed. For other infrequently accessed data, such as duplicates of backups or data summaries that can be regenerated, S3 One Zone-IA provides a lower price point.
Data can be uploaded directly into S3 One Zone-IA, or can be populated by using S3 Lifecycle policies to tier data into S3 One Zone-IA. S3 One Zone-IA is available today in all AWS commercial Regions.
