Amazon S3 drops 30-day minimum for Standard-IA and One Zone-IA transitions
Amazon S3 now allows immediate transitions to Standard-IA and One Zone-IA storage classes, eliminating the previous 30-day minimum retention in S3 Standard. This change offers up to 40% lower storage costs for data accessed infrequently, benefiting workloads like backups and log analytics. Users can configure these rules starting from 0 days after object creation via the S3 console, AWS CLI, or SDKs across all available regions.

Features (1) ›
- Immediate object transitions to S3 Standard-IA and One Zone-IA
Amazon S3 has removed the 30-day minimum retention requirement for transitioning objects to S3 Standard-Infrequent Access (S3 Standard-IA) and S3 One Zone-Infrequent Access (S3 One Zone-IA) from S3 Standard. This enables cost savings for data that becomes less frequently accessed soon after creation.
Enhancements (2) ›
- Reduced storage costs for infrequently accessed data
S3 Standard-IA and S3 One Zone-IA now offer up to 40% lower storage costs compared to S3 Standard while maintaining millisecond access. This makes them suitable for workloads such as backups, log analytics, and compliance where data access patterns are predictable.
- Flexible S3 Lifecycle rule configuration
Users can now create new S3 Lifecycle rules to transition objects to S3 Standard-IA and S3 One Zone-IA as soon as 0 days after creation. Configuration is available through the S3 console, AWS CLI, and SDKs.
