create_replication_configuration¶

EFS.Client.create_replication_configuration(**kwargs)¶

Creates a replication configuration that replicates an existing EFS file system to a new, read-only file system. For more information, see Amazon EFS replication in the Amazon EFS User Guide . The replication configuration specifies the following:

Source file system - An existing EFS file system that you want replicated. The source file system cannot be a destination file system in an existing replication configuration.
Destination file system configuration - The configuration of the destination file system to which the source file system will be replicated. There can only be one destination file system in a replication configuration. The destination file system configuration consists of the following properties:
- Amazon Web Services Region - The Amazon Web Services Region in which the destination file system is created. Amazon EFS replication is available in all Amazon Web Services Regions that Amazon EFS is available in, except Africa (Cape Town), Asia Pacific (Hong Kong), Asia Pacific (Jakarta), Europe (Milan), and Middle East (Bahrain).
- Availability Zone - If you want the destination file system to use EFS One Zone availability and durability, you must specify the Availability Zone to create the file system in. For more information about EFS storage classes, see Amazon EFS storage classes in the Amazon EFS User Guide .
- Encryption - All destination file systems are created with encryption at rest enabled. You can specify the Key Management Service (KMS) key that is used to encrypt the destination file system. If you don't specify a KMS key, your service-managed KMS key for Amazon EFS is used.
Note

After the file system is created, you cannot change the KMS key.

The following properties are set by default:

Performance mode - The destination file system's performance mode matches that of the source file system, unless the destination file system uses EFS One Zone storage. In that case, the General Purpose performance mode is used. The performance mode cannot be changed.
Throughput mode - The destination file system's throughput mode matches that of the source file system. After the file system is created, you can modify the throughput mode.

The following properties are turned off by default:

Lifecycle management - EFS lifecycle management and EFS Intelligent-Tiering are not enabled on the destination file system. After the destination file system is created, you can enable EFS lifecycle management and EFS Intelligent-Tiering.
Automatic backups - Automatic daily backups not enabled on the destination file system. After the file system is created, you can change this setting.

For more information, see Amazon EFS replication in the Amazon EFS User Guide .

Request Syntax

response = client.create_replication_configuration(
    SourceFileSystemId='string',
    Destinations=[
        {
            'Region': 'string',
            'AvailabilityZoneName': 'string',
            'KmsKeyId': 'string'
        },
    ]
)

Parameters

SourceFileSystemId (string) --
[REQUIRED]

Specifies the Amazon EFS file system that you want to replicate. This file system cannot already be a source or destination file system in another replication configuration.
Destinations (list) --
[REQUIRED]

An array of destination configuration objects. Only one destination configuration object is supported.
- (dict) --
  Describes the destination file system to create in the replication configuration.
  - Region (string) --
    To create a file system that uses Regional storage, specify the Amazon Web Services Region in which to create the destination file system.
  - AvailabilityZoneName (string) --
    To create a file system that uses EFS One Zone storage, specify the name of the Availability Zone in which to create the destination file system.
  - KmsKeyId (string) --
    Specifies the Key Management Service (KMS) key that you want to use to encrypt the destination file system. If you do not specify a KMS key, Amazon EFS uses your default KMS key for Amazon EFS, /aws/elasticfilesystem . This ID can be in one of the following formats:
    - Key ID - The unique identifier of the key, for example 1234abcd-12ab-34cd-56ef-1234567890ab .
    - ARN - The Amazon Resource Name (ARN) for the key, for example arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab .
    - Key alias - A previously created display name for a key, for example alias/projectKey1 .
    - Key alias ARN - The ARN for a key alias, for example arn:aws:kms:us-west-2:444455556666:alias/projectKey1 .

Response Structure

(dict) --
- SourceFileSystemId (string) --
  
  The ID of the source Amazon EFS file system that is being replicated.
- SourceFileSystemRegion (string) --
  
  The Amazon Web Services Region in which the source Amazon EFS file system is located.
- SourceFileSystemArn (string) --
  
  The Amazon Resource Name (ARN) of the current source file system in the replication configuration.
- OriginalSourceFileSystemArn (string) --
  
  The Amazon Resource Name (ARN) of the original source Amazon EFS file system in the replication configuration.
- CreationTime (datetime) --
  
  Describes when the replication configuration was created.
- Destinations (list) --
  
  An array of destination objects. Only one destination object is supported.
  - (dict) --
    
    Describes the destination file system in the replication configuration.
    - Status (string) --
      
      Describes the status of the destination Amazon EFS file system. If the status is ERROR , the destination file system in the replication configuration is in a failed state and is unrecoverable. To access the file system data, restore a backup of the failed file system to a new file system.
    - FileSystemId (string) --
      
      The ID of the destination Amazon EFS file system.
    - Region (string) --
      
      The Amazon Web Services Region in which the destination file system is located.
    - LastReplicatedTimestamp (datetime) --
      
      The time when the most recent sync was successfully completed on the destination file system. Any changes to data on the source file system that occurred before this time have been successfully replicated to the destination file system. Any changes that occurred after this time might not be fully replicated.
