What are the different storage classes available in EFS?

Answer

EFS offers Standard storage for frequently accessed files, Infrequent Access storage which costs less but has a small retrieval fee for files not accessed often, and within each of these, One Zone options that store data in a single Availability Zone at a lower cost compared to the Standard multi Availability Zone options, letting you balance cost against durability requirements.

aws efs put-lifecycle-configuration --file-system-id fs-12345678 --lifecycle-policies '[{"TransitionToIA":"AFTER_30_DAYS"}]'

Real-world example A media company configures a lifecycle policy that automatically moves files untouched for thirty days into EFS Infrequent Access storage, significantly reducing its overall storage costs for older, rarely accessed project files.
