## AWS Backup and EFS

* **Note**\
  Automatic backups are exempt from the AWS Backup service opt-out configuration. For more information, see [Getting Started with AWS Backup](https://docs.aws.amazon.com/aws-backup/latest/devguide/getting-started.html) in the *AWS Backup Developer Guide*.
* **Note**\
  Sockets and named pipes are not supported, and are omitted from backups.
* **Note**\
  To restore a recovery point, users must have the `backup:StartRestoreJob` permission.
* **Note**\
  For Partial restores to an existing EFS file system, AWS Backup restores the files and directories to a new directory under the file system root directory. The full hierarchy of the specified items is preserved in the recovery directory. For example, if directory A contains subdirectories B, C, and D, AWS Backup retains the hierarchical structure when A, B, C, and D are recovered.
