Ensure that your Amazon EFS file systems utilize Lifecycle Management to efficiently manage EFS data during its lifetime and reduce storage costs for infrequently accessed files. Lifecycle Management feature automatically moves your Amazon EFS files to the lower-cost Infrequent Access (IA) storage class based on a predefined lifecycle policy in order to implement cost-effective file storage management.
The storage classes made available for AWS EFS file systems are Standard – a storage class that is used to store frequently accessed files and Infrequent Access (IA) – a lower cost storage class that is designed for storing infrequently accessed files in a cost-effective manner. The IA storage class reduces storage costs for files that are not repeatedly accessed, without altering the high availability, high durability, elasticity or POSIX file system access that AWS EFS service provides. With Lifecycle Management feature enabled, you can make use of EFS IA storage class for keeping you files accessible in order to satisfy audit requirements, perform historical analysis or backup and recovery, while lowering your EFS costs.
