DescribeLifecycleConfiguration
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.
