EFS / Client / describe_lifecycle_configuration

describe_lifecycle_configuration

EFS.Client.describe_lifecycle_configuration(**kwargs)

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.

Response Syntax

{
    'LifecyclePolicies': [
        {
            'TransitionToIA': 'AFTER_7_DAYS'|'AFTER_14_DAYS'|'AFTER_30_DAYS'|'AFTER_60_DAYS'|'AFTER_90_DAYS'|'AFTER_1_DAY',

    ]
}

Response Structure

• (dict) –

  • LifecyclePolicies (list) –

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

    • (dict) –

      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.

      Note

      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 must 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.

Exceptions

• EFS.Client.exceptions.InternalServerError

• EFS.Client.exceptions.BadRequest

• EFS.Client.exceptions.FileSystemNotFound

Examples

This operation describes a file system’s LifecycleConfiguration. EFS lifecycle management uses the LifecycleConfiguration object to identify which files to move to the EFS Infrequent Access (IA) storage class.

response = client.describe_lifecycle_configuration(
    FileSystemId='fs-01234567',
)

print(response)

Expected Output:

{
    'LifecyclePolicies': [
        {
            'TransitionToIA': 'AFTER_30_DAYS',
        },
    ],
    'ResponseMetadata': {
        '...': '...',
    },
