The One Zone-Infrequent Access Storage Class Overview
Amazon S3 team introduced the new low-cost storage class for re-creatable data, such as secondary copies of your backups or for data that is already replicated in another AWS Region for compliance or disaster recovery purposes.
The new S3 One Zone-Infrequent Access (ONEZONE_IA) storage class offers the same high durability (99.999999999%), low latency, and high throughput of S3 Standard or Standard-IA and inherits all of the existing S3 features including security and access management, data lifecycle policies, cross-region replication, and event notifications.
With S3 One Zone-IA, you can store infrequently accessed data within a single Availability Zone at 20% lower cost than S3 Standard-IA.
You can find more details in the official AWS blog. Below we will describe how to take advantage of this new storage class with S3 Browser.
