This operation activates the gateway you previously deployed on your host. For more information, see Downloading and Deploying AWS Storage Gateway VM . In the activation process you specify information such as the region you want to use for storing snapshots, the time zone for scheduled snapshots and the gateway schedule window, an activation key, and a name for your gateway. The activation process also associates your gateway with your account (see UpdateGatewayInformation).

NOTE:You must power on the gateway VM before you can activate your gateway.

In the request, you specify the gateway Amazon Resource Name (ARN) to which you want to add cache, and one or more disk IDs that you want to configure as cache.

• Storage gateways of all types

• Storage Volumes

• Virtual Tapes

You can create a maximum of 10 tags for each resource. Virtual tapes and storage volumes that are recovered to a new gateway maintain their tags.

This operation configures one or more gateway local disks as upload buffer for a specified gateway. This operation is supported for both the gateway-stored and gateway-cached volume architectures.

In the request, you specify the gateway Amazon Resource Name (ARN) to which you want to add upload buffer, and one or more disk IDs that you want to configure as upload buffer.

This operation configures one or more gateway local disks as working storage for a gateway. This operation is supported only for the gateway-stored volume architecture. This operation is deprecated method in cached-volumes API version (20120630). Use AddUploadBuffer instead.

NOTE: Working storage is also referred to as upload buffer. You can also use the AddUploadBuffer operation to add upload buffer to a stored-volume gateway.

In the request, you specify the gateway Amazon Resource Name (ARN) to which you want to add working storage, and one or more disk IDs that you want to configure as working storage.

Cancels archiving of a virtual tape to the virtual tape shelf (VTS) after the archiving process is initiated.

CancelRetrievalOutput

Describes Challenge-Handshake Authentication Protocol (CHAP) information that supports authentication between your gateway and iSCSI initiators.

In the request, you must specify the gateway, size of the volume in bytes, the iSCSI target name, an IP address on which to expose the target, and a unique client token. In response, AWS Storage Gateway creates the volume and returns information about it. This information includes the volume Amazon Resource Name (ARN), its size, and the iSCSI target ARN that initiators can use to connect to the volume target.

Optionally, you can provide the ARN for an existing volume as the SourceVolumeARN for this cached volume, which creates an exact copy of the existing volume’s latest recovery point. The VolumeSizeInBytes value must be equal to or larger than the size of the copied volume, in bytes.

This operation initiates a snapshot of a gateway from a volume recovery point. This operation is supported only for the gateway-cached volume architecture (see ).

A volume recovery point is a point in time at which all data of the volume is consistent and from which you can create a snapshot. To get a list of volume recovery point for gateway-cached volumes, use ListVolumeRecoveryPoints.

In the CreateSnapshotFromVolumeRecoveryPoint request, you identify the volume by providing its Amazon Resource Name (ARN). You must also provide a description for the snapshot. When AWS Storage Gateway takes a snapshot of the specified volume, the snapshot and its description appear in the AWS Storage Gateway console. In response, AWS Storage Gateway returns you a snapshot ID. You can use this snapshot ID to check the snapshot progress or later use it when you want to create a volume from a snapshot.

NOTE: To list or delete a snapshot, you must use the Amazon EC2 API. For more information, in Amazon Elastic Compute Cloud API Reference.

AWS Storage Gateway provides the ability to back up point-in-time snapshots of your data to Amazon Simple Storage (S3) for durable off-site recovery, as well as import the data to an Amazon Elastic Block Store (EBS) volume in Amazon Elastic Compute Cloud (EC2). You can take snapshots of your gateway volume on a scheduled or ad-hoc basis. This API enables you to take ad-hoc snapshot. For more information, see Working With Snapshots in the AWS Storage Gateway Console.

In the CreateSnapshot request you identify the volume by providing its Amazon Resource Name (ARN). You must also provide description for the snapshot. When AWS Storage Gateway takes the snapshot of specified volume, the snapshot and description appears in the AWS Storage Gateway Console. In response, AWS Storage Gateway returns you a snapshot ID. You can use this snapshot ID to check the snapshot progress or later use it when you want to create a volume from a snapshot.

A JSON object containing the following fields:

• CreateSnapshotOutput$SnapshotId
• CreateSnapshotOutput$VolumeARN

This operation creates a volume on a specified gateway. This operation is supported only for the gateway-stored volume architecture.

The size of the volume to create is inferred from the disk size. You can choose to preserve existing data on the disk, create volume from an existing snapshot, or create an empty volume. If you choose to create an empty gateway volume, then any existing data on the disk is erased.

In the request you must specify the gateway and the disk information on which you are creating the volume. In response, AWS Storage Gateway creates the volume and returns volume information such as the volume Amazon Resource Name (ARN), its size, and the iSCSI target ARN that initiators can use to connect to the volume target.

Creates one or more virtual tapes. You write data to the virtual tapes and then archive the tapes.

NOTE:Cache storage must be allocated to the gateway before you can create virtual tapes. Use the AddCache operation to add cache storage to a gateway.

A JSON object containing the following fields:

This operation deletes a gateway. To specify which gateway to delete, use the Amazon Resource Name (ARN) of the gateway in your request. The operation deletes the gateway; however, it does not delete the gateway virtual machine (VM) from your host computer.

After you delete a gateway, you cannot reactivate it. Completed snapshots of the gateway volumes are not deleted upon deleting the gateway, however, pending snapshots will not complete. After you delete a gateway, your next step is to remove it from your environment.

IMPORTANT: You no longer pay software charges after the gateway is deleted; however, your existing Amazon EBS snapshots persist and you will continue to be billed for these snapshots. You can choose to remove all remaining Amazon EBS snapshots by canceling your Amazon EC2 subscription.  If you prefer not to cancel your Amazon EC2 subscription, you can delete your snapshots using the Amazon EC2 console. For more information, see the AWS Storage Gateway Detail Page.

This operation deletes a snapshot of a volume.

You can take snapshots of your gateway volumes on a scheduled or ad-hoc basis. This API enables you to delete a snapshot schedule for a volume. For more information, see Working with Snapshots . In the DeleteSnapshotSchedule request, you identify the volume by providing its Amazon Resource Name (ARN).

NOTE: To list or delete a snapshot, you must use the Amazon EC2 API. in Amazon Elastic Compute Cloud API Reference.

DeleteTapeArchiveOutput

DeleteTapeOutput

Before you delete a gateway volume, make sure there are no iSCSI connections to the volume you are deleting. You should also make sure there is no snapshot in progress. You can use the Amazon Elastic Compute Cloud (Amazon EC2) API to query snapshots on the volume you are deleting and check the snapshot status. For more information, go to DescribeSnapshots in the Amazon Elastic Compute Cloud API Reference.

In the request, you must provide the Amazon Resource Name (ARN) of the storage volume you want to delete.

This operation only returns a value for a bandwidth rate limit only if the limit is set. If no limits are set for the gateway, then this operation returns only the gateway ARN in the response body.

By default, the operation returns a maximum of 100 gateways. This operation supports pagination that allows you to optionally reduce the number of gateways returned in a response.

If you have more gateways than are returned in a response (that is, the response returns only a truncated list of your gateways), the response contains a marker that you can specify in your next request to fetch the next page of gateways.

This operation returns a list of the local disks of a gateway. To specify which gateway to describe you use the Amazon Resource Name (ARN) of the gateway in the body of the request.

The request returns all disks, specifying which are configured as working storage, stored volume or not configured at all.

This operation supports pagination. By default, the operation returns a maximum of up to 100 tapes. You can optionally specify the Limit parameter in the body to limit the number of tapes in the response. If the number of tapes returned in the response is truncated, the response includes a Marker element that you can use in your subsequent request to retrieve the next set of tapes.

• ListTapesOutput$Marker

• ListTapesOutput$VolumeInfos

Each gateway-cached volume has one recovery point. A volume recovery point is a point in time at which all data of the volume is consistent and from which you can create a snapshot. To create a snapshot from a volume recovery point use the CreateSnapshotFromVolumeRecoveryPoint operation.

This operation lists the iSCSI stored volumes of a gateway. Results are sorted by volume ARN. The response includes only the volume ARNs. If you want additional volume information, use the DescribeStorediSCSIVolumes API.

If the number of volumes returned in the response is truncated, the response includes a Marker field. You can use this Marker value in your subsequent request to retrieve the next set of volumes.

Describes a gateway's network interface.

Retrieves an archived virtual tape from the virtual tape shelf (VTS) to a gateway-VTL. Virtual tapes archived in the VTS are not associated with any gateway. However after a tape is retrieved, it is associated with a gateway, even though it is also listed in the VTS.

Once a tape is successfully retrieved to a gateway, it cannot be retrieved again to another gateway. You must archive the tape again before you can retrieve it to another gateway.

RetrieveTapeArchiveOutput

Retrieves the recovery point for the specified virtual tape.

A recovery point is a point in time view of a virtual tape at which all the data on the tape is consistent. If your gateway crashes, virtual tapes that have recovery points can be recovered to a new gateway.

NOTE:The virtual tape can be retrieved to only one gateway. The retrieved tape is read-only. The virtual tape can be retrieved to only a gateway-VTL. There is no charge for retrieving recovery points.

The operation shuts down the gateway service component running in the storage gateway's virtual machine (VM) and not the VM.

After the gateway is shutdown, you cannot call any other API except StartGateway, DescribeGatewayInformation, and ListGateways. For more information, see ActivateGateway. Your applications cannot read from or write to the gateway's storage volumes, and there are no snapshots taken.

If do not intend to use the gateway again, you must delete the gateway (using DeleteGateway) to no longer pay software charges associated with the gateway.

A JSON object containing the of the gateway that was shut down.

To specify which gateway to start, use the Amazon Resource Name (ARN) of the gateway in your request.

By default, a gateway's bandwidth rate limits are not set. If you don't set any limit, the gateway does not have any limitations on its bandwidth usage and could potentially use the maximum available bandwidth.

To specify which gateway to update, use the Amazon Resource Name (ARN) of the gateway in your request.

This operation updates the Challenge-Handshake Authentication Protocol (CHAP) credentials for a specified iSCSI target. By default, a gateway does not have CHAP enabled; however, for added security, you might use it.

IMPORTANT: When you update CHAP credentials, all existing connections on the target are closed and initiators must reconnect with the new credentials.

This operation updates a gateway's metadata, which includes the gateway's name and time zone. To specify which gateway to update, use the Amazon Resource Name (ARN) of the gateway in your request.

A JSON object containing the GatewayARN of the gateway that was updated.

This operation updates the gateway virtual machine (VM) software. The request immediately triggers the software update.

NOTE:When you make this request, you get a 200 OK success response immediately. However, it might take some time for the update to complete. You can call DescribeGatewayInformation to verify the gateway is in the STATE_RUNNING state.

IMPORTANT:A software update forces a system restart of your gateway. You can minimize the chance of any disruption to your applications by increasing your iSCSI Initiators' timeouts. For more information about increasing iSCSI Initiator timeouts for Windows and Linux, see Customizing Your Windows iSCSI Settings and Customizing Your Linux iSCSI Settings, respectively.
