The One Zone-Infrequent Access Storage Class

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 CS Browser.

To apply the One Zone-IA storage class for existing files

1. Start CS Browser and select the file(s) and/or folder(s) you want to change storage class for.

2. Click Files, Change Storage Class to, ONEZONE_IA

   

3. CS Browser will update storage class for selected files and refresh files list.

To apply the One Zone-IA storage class for an entire Bucket

1. Start CS Browser and select the bucket you want to change storage class for.

2. Click Buckets, Change Storage Class to, ONEZONE_IA

   

3. CS Browser will apply selected storage class for all files inside the bucket.

   If your Amazon S3 Bucket contains a lot of files, this operation may take a while. You can significantly increase performance with CS Browser Pro. It allows you to increase the number of concurrent working threads and thereby process your files much more faster!
