[ aws . fsx ]



Creates a new Amazon FSx file system from an existing Amazon FSx for Windows File Server backup.

If a file system with the specified client request token exists and the parameters match, this operation returns the description of the file system. If a client request token specified by the file system exists and the parameters don't match, this call returns IncompatibleParameterError . If a file system with the specified client request token doesn't exist, this operation does the following:

  • Creates a new Amazon FSx file system from backup with an assigned ID, and an initial lifecycle state of CREATING .
  • Returns the description of the file system.

Parameters like Active Directory, default share name, automatic backup, and backup settings default to the parameters of the file system that was backed up, unless overridden. You can explicitly supply other settings.

By using the idempotent operation, you can retry a CreateFileSystemFromBackup call without the risk of creating an extra file system. This approach can be useful when an initial call fails in a way that makes it unclear whether a file system was created. Examples are if a transport level timeout occurred, or your connection was reset. If you use the same client request token and the initial call created a file system, the client receives success as long as the parameters are the same.


The CreateFileSystemFromBackup call returns while the file system's lifecycle state is still CREATING . You can check the file-system creation status by calling the DescribeFileSystems operation, which returns the file system state along with other information.

--backup-id (string)

The ID of the backup. Specifies the backup to use if you're creating a file system from an existing backup.

--client-request-token (string)

(Optional) A string of up to 64 ASCII characters that Amazon FSx uses to ensure idempotent creation. This string is automatically filled on your behalf when you use the AWS Command Line Interface (AWS CLI) or an AWS SDK.

--subnet-ids (list)

A list of IDs for the subnets that the file system will be accessible from. Currently, you can specify only one subnet. The file server is also launched in that subnet's Availability Zone.


"string" "string" ...

--security-group-ids (list)

A list of IDs for the security groups that apply to the specified network interfaces created for file system access. These security groups apply to all network interfaces. This value isn't returned in later describe requests.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

NetworkInterfaceIds -> (list)

The IDs of the elastic network interface from which a specific file system is accessible. The elastic network interface is automatically created in the same VPC that the Amazon FSx file system was created in. For more information, see Elastic Network Interfaces in the Amazon EC2 User Guide.

For an Amazon FSx for Windows File Server file system, you can have one network interface ID. For an Amazon FSx for Lustre file system, you can have more than one.


An elastic network interface ID. An elastic network interface is a logical networking component in a virtual private cloud (VPC) that represents a virtual network card. For more information, see Elastic Network Interfaces in the Amazon EC2 User Guide for Linux Instances .
