Save up to 92% on file storage

Maximizing operational efficiency and reducing total cost of ownership are common drivers for moving business applications to the cloud.

Amazon Elastic File System (Amazon EFS) provides a simple, scalable, fully managed, elastic, NFS file system for use with AWS Cloud services and on-premises resources. Amazon EFS Infrequent Access (EFS IA) is a storage class that provides price/performance that is cost-optimized for files not accessed everyday, with storage prices up to 92% lower compared to Amazon EFS Standard. The EFS IA storage class costs only $0.025/GB-month*.

Using the industry accepted estimate that 20% of data is actively used and 80% is infrequently accessed, you can store your files on EFS at an effective price as low as $0.08/GB-month* (20% x $0.30/GB-month for files stored on EFS Standard + 80% x $0.025/GB-month for files stored on EFS IA = $0.08/GB-month).

To get started with EFS IA, simply enable EFS Lifecycle Management for your file system by selecting a lifecycle policy that matches your needs. EFS will automatically move your files to the lower cost EFS IA storage class based on the last time they were accessed. EFS transparently serves files from both storage classes - EFS Standard and EFS IA - from a common file system namespace, so you don't have to worry about which of your files are actively used and which are infrequently accessed.

Optimize Costs with Amazon EFS IA - re:Invent 2018 (25:32)

How it works

product-page-diagram-Amazon-EFS-Infrequent-Access-How-It-Works
  1. Create file system
  2. Choose Lifecycle Management file access policy (14, 30, 60, or 90 days) using the AWS CLI, API, or EFS Management Console
  3. Files not accessed according to the age-off policy are moved to EFS IA

Use cases for Amazon EFS IA

Backup & Recovery

EFS IA cost effectively stores file data, with industry-leading availability, security and durability enabling you to meet regulatory retention and compliance needs so your backups are protected and available when needed.

Analytics

Managing the massive volume of big data analytics can be costly and complex for workloads like genomics and geospatial applications. EFS IA cost-effectively stores large amounts of data while providing the same throughput to scale applications with files stored in EFS Standard.

Document Management

Many reporting systems for business applications rely on accessible shared file storage in support of business functions. With EFS IA, customers can now easily and cost-effectively store and access their shared file system, eliminating the need to manage data to control costs.
