DestinationToCreate

Describes the new or existing destination file system for the replication configuration.

• If you want to replicate to a new file system, do not specify the File System ID for the destination file system. Amazon EFS creates a new, empty file system. For One Zone storage, specify the Availability Zone to create the file system in. To use an Key Management Service key other than the default KMS key, then specify it. For more information, see Configuring replication to new Amazon EFS file system in the Amazon EFS User Guide.After the file system is created, you cannot change the KMS key or the performance mode.

• If you want to replicate to an existing file system that's in the same account as the source file system, then you need to provide the ID or Amazon Resource Name (ARN) of the file system to which to replicate. The file system's replication overwrite protection must be disabled. For more information, see Replicating to an existing file system in the Amazon EFS User Guide.

• If you are replicating the file system to a file system that's in a different account than the source file system (cross-account replication), you need to provide the ARN for the file system and the IAM role that allows Amazon EFS to perform replication on the destination account. The file system's replication overwrite protection must be disabled. For more information, see Replicating across Amazon Web Services accounts in the Amazon EFS User Guide.
