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, serverless, set-and-forget elastic file system for use with AWS Cloud services and on-premises resources. Amazon EFS Standard-Infrequent Access (EFS Standard-IA) and Amazon EFS One Zone-Infrequent Access (EFS One Zone-IA) are storage classes that provide price/performance that is cost-optimized for files not accessed every day, with storage prices up to 92% lower compared to Amazon EFS Standard (EFS Standard) and Amazon EFS One Zone (EFS One Zone) storage classes respectively. The EFS Standard-IA storage class costs only $0.025/GB-month1, and the EFS One Zone-IA storage class costs only $0.0133/GB-month2.
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 of $0.043/GB-month (20% $0.16/GB-month1 for files stored on EFS One Zone + 80% $0.0133/GB-month1 for files stored on EFS One Zone-IA = $0.043/GB-month)1, or an effective price of $0.08/GB-month (20% $0.30/GB-month2 for files stored on EFS Standard + 80% $0.025/GB-month2 for files stored on to EFS Standard-IA storage class = $0.08/GB-month)2.
To get started with Infrequent Access storage classes, simply enable Amazon EFS Lifecycle Management for your file system by selecting a lifecycle policy that matches your needs. Amazon EFS will automatically and transparently move your files to lower cost regional EFS Standard-IA storage class or EFS One Zone-IA storage class based on the last time they were accessed. Amazon EFS transparently serves files from both frequently accessed (such as EFS Standard and EFS One Zone) and infrequent access (such as EFS Standard-IA and EFS One Zone-IA) storage classes 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.

How it works
- Create file system
- Choose Lifecycle Management file access policy (7, 14, 30, 60, or 90 days) using the AWS CLI, API, or Amazon EFS Management Console
- Files not accessed according to the age-off policy are moved to the EFS Standard-IA or EFS One Zone-IA storage class, depending on whether your file system uses Standard or One Zone storage classes.
Use Cases for Infrequent Access Storage
Backup & Recovery
EFS Standard-IA and EFS One Zone-IA storage classes cost effectively store 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.
Managing massive volumes of big data analytics can be costly and complex for workloads like genomics and geospatial applications. EFS Standard-IA and EFS One Zone-IA storage classes cost-effectively store large amounts of data while providing the same throughput used to scale applications with files stored in EFS Standard and EFS One Zone storage classes.
Many reporting systems for business applications rely on accessible shared file storage in support of business functions. With EFS Standard-IA and EFS One Zone-IA storage classes, you can easily and cost-effectively store and access files from shared file systems, eliminating the need to manage data to control costs.
Amazon EFS One Zone storage classes are cost-optimized for workloads that do not require the level of availability and durability offered by Amazon EFS Standard storage classes, which store data redundantly across multiple geographically separated Availability Zones.
Tens of thousands of customers including T-Mobile, MicroStrategy, HERE, and LoanLogics are storing up to petabytes of data in Amazon EFS, to power use cases such as enterprise applications, large scale analytics, and persistent file storage for modern applications.
