import { aws_efs as efs } from 'aws-cdk-lib';
import { aws_kms as kms } from 'aws-cdk-lib';
import { aws_efs as interfaces_efs } from 'aws-cdk-lib/interfaces';

declare const fileSystemRef: interfaces_efs.IFileSystemRef;
declare const key: kms.Key;
const replicationConfigurationProps: efs.ReplicationConfigurationProps = {
  availabilityZone: 'availabilityZone',
  destinationFileSystem: fileSystemRef,
  kmsKey: key,
  region: 'region',
};
```

## Properties
