First time using the AWS CLI? See the User Guide for help getting started.

Note: You are viewing the documentation for an older major version of the AWS CLI (version 1).

AWS CLI version 2, the latest major version of AWS CLI, is now stable and recommended for general use. To view this page for the AWS CLI version 2, click here. For more information see the AWS CLI version 2 installation instructions and migration guide.

[ aws . efs ]



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.

See 'aws help' for descriptions of global parameters.


--file-system-id <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--file-system-id (string)

The ID of the file system whose LifecycleConfiguration object you want to retrieve (String).

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


LifecyclePolicies -> (list)

An array of lifecycle management policies. EFS supports a maximum of one policy per file system.


Describes a policy used by EFS lifecycle management and EFS intelligent tiering that specifies when to transition files into and out of the file system's Infrequent Access (IA) storage class. For more information, see EFS Intelligent‐Tiering and EFS Lifecycle Management .


When using the put-lifecycle-configuration CLI command or the PutLifecycleConfiguration API action, Amazon EFS requires that each LifecyclePolicy object have only a single transition. This means that in a request body, LifecyclePolicies needs to be structured as an array of LifecyclePolicy objects, one object for each transition, TransitionToIA , TransitionToPrimaryStorageClass . For more information, see the request examples in PutLifecycleConfiguration .

TransitionToIA -> (string)

Describes the period of time that a file is not accessed, after which it transitions to IA storage. Metadata operations such as listing the contents of a directory don't count as file access events.

TransitionToPrimaryStorageClass -> (string)

Describes when to transition a file from IA storage to primary storage. Metadata operations such as listing the contents of a directory don't count as file access events.
