DescribeLifecycleConfiguration - Amazon Elastic File System


Returns the current LifecycleConfiguration object for the specified Amazon EFS file system. EFS lifecycle management uses the LifecycleConfiguration object to identify which files to move to the EFS Infrequent Access (IA) storage class. For a file system without a LifecycleConfiguration object, the call returns an empty array in the response.

When EFS Intelligent-Tiering is enabled, TransitionToPrimaryStorageClass has a value of AFTER_1_ACCESS.

This operation requires permissions for the elasticfilesystem:DescribeLifecycleConfiguration operation.
