Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

You can use the Amazon Elastic Block Store (Amazon EBS) direct APIs to create EBS snapshots, write data directly to your snapshots, read data on your snapshots, and identify the differences or changes between two snapshots. If you’re an independent software vendor (ISV) who offers backup services for Amazon EBS, the EBS direct APIs make it more efficient and cost-effective to track incremental changes on your EBS volumes through snapshots. This can be done without having to create new volumes from snapshots, and then use Amazon Elastic Compute Cloud (Amazon EC2) instances to compare the differences.

You can create incremental snapshots directly from data on-premises into EBS volumes and the cloud to use for quick disaster recovery. With the ability to write and read snapshots, you can write your on-premises data to an EBS snapshot during a disaster. Then after recovery, you can restore it back to AWS or on-premises from the snapshot. You no longer need to build and maintain complex mechanisms to copy data to and from Amazon EBS.

This API reference provides detailed information about the actions, data types, parameters, and errors of the EBS direct APIs. For more information about the elements that make up the EBS direct APIs, and examples of how to use them effectively, see Accessing the Contents of an EBS Snapshot in the Amazon Elastic Compute Cloud User Guide. For more information about the supported AWS Regions, endpoints, and service quotas for the EBS direct APIs, see Amazon Elastic Block Store Endpoints and Quotas in the AWS General Reference.

Sending a Request Using EBS

var ebs = new AWS.EBS();
ebs.completeSnapshot(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the EBS object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var ebs = new AWS.EBS({apiVersion: '2019-11-02'});

You can also set the API version globally in AWS.config.apiVersions using the ebs service identifier:

AWS.config.apiVersions = {
  ebs: '2019-11-02',
  // other service API versions
};

var ebs = new AWS.EBS();

Service Reference:

Examples:

Calling the putSnapshotBlock operation

var params = {
  BlockData: Buffer.from('...') || 'STRING_VALUE' || streamObject, /* required */

    • SnapshotId — (String)

      The ID of the snapshot.

    • BlockIndex — (Integer)

      The block index of the block in which to write the data. A block index is a logical index in units of 512 KiB blocks.

      The block data is not signed as part of the Signature Version 4 signing process. As a result, you must generate and provide a Base64-encoded SHA256 checksum for the block data using the x-amz-Checksum header. Also, you must specify the checksum algorithm using the x-amz-Checksum-Algorithm header. The checksum that you provide is part of the Signature Version 4 signing process. It is validated against a checksum generated by Amazon EBS to ensure the validity and authenticity of the data. If the checksums do not correspond, the request fails. For more information, see Using checksums with the EBS direct APIs in the Amazon Elastic Compute Cloud User Guide.

    • DataLength — (Integer)

      The size of the data to write to the block, in bytes. Currently, the only supported size is 524288.

      Valid values: 524288

    • Progress — (Integer)

      The progress of the write process, as a percentage.

    • Checksum — (String)

      A Base64-encoded SHA256 checksum of the data. Only SHA256 checksums are supported.

    • ChecksumAlgorithm — (String)

      The algorithm used to generate the checksum. Currently, the only supported algorithm is SHA256.

      Possible values include:
      • "SHA256"

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • Checksum — (String)

        The SHA256 checksum generated for the block data by Amazon EBS.

      • ChecksumAlgorithm — (String)

        The algorithm used by Amazon EBS to generate the checksum.

        Possible values include:
        • "SHA256"

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

startSnapshot(params = {}, callback) ⇒ AWS.Request

Creates a new Amazon EBS snapshot. The new snapshot enters the pending state after the request completes.

After creating the snapshot, use PutSnapshotBlock to write blocks of data to the snapshot.

Service Reference:

Examples:

Calling the startSnapshot operation

var params = {
  VolumeSize: 'NUMBER_VALUE', /* required */
  ClientToken: 'STRING_VALUE',
  Description: 'STRING_VALUE',
  Encrypted: true || false,
  KmsKeyArn: 'STRING_VALUE',
  ParentSnapshotId: 'STRING_VALUE',
  Tags: [
    {
      Key: 'STRING_VALUE',
      Value: 'STRING_VALUE'
    },
    /* more items */
  ],
  Timeout: 'NUMBER_VALUE'
};
ebs.startSnapshot(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • VolumeSize — (Integer)

      The size of the volume, in GiB. The maximum size is 16384 GiB (16 TiB).

    • ParentSnapshotId — (String)

      The ID of the parent snapshot. If there is no parent snapshot, or if you are creating the first snapshot for an on-premises volume, omit this parameter.

      If your account is enabled for encryption by default, you cannot use an unencrypted snapshot as a parent snapshot. You must first create an encrypted copy of the parent snapshot using CopySnapshot.

    • Tags — (Array<map>)

      The tags to apply to the snapshot.

      • Key — (String)

        The key of the tag.

      • Value — (String)

        The value of the tag.

    • Description — (String)

      A description for the snapshot.

    • ClientToken — (String)

      A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. Idempotency ensures that an API request completes only once. With an idempotent request, if the original request completes successfully. The subsequent retries with the same client token return the result from the original successful request and they have no additional effect.

      If you do not specify a client token, one is automatically generated by the AWS SDK.

      For more information, see Idempotency for StartSnapshot API in the Amazon Elastic Compute Cloud User Guide.

      If a token is not provided, the SDK will use a version 4 UUID.
    • Encrypted — (Boolean)

      Indicates whether to encrypt the snapshot. To create an encrypted snapshot, specify true. To create an unencrypted snapshot, omit this parameter.

      If you specify a value for ParentSnapshotId, omit this parameter.

      If you specify true, the snapshot is encrypted using the CMK specified using the KmsKeyArn parameter. If no value is specified for KmsKeyArn, the default CMK for your account is used. If no default CMK has been specified for your account, the AWS managed CMK is used. To set a default CMK for your account, use ModifyEbsDefaultKmsKeyId.

      If your account is enabled for encryption by default, you cannot set this parameter to false. In this case, you can omit this parameter.

      For more information, see Using encryption in the Amazon Elastic Compute Cloud User Guide.

    • KmsKeyArn — (String)

      The Amazon Resource Name (ARN) of the AWS Key Management Service (AWS KMS) customer master key (CMK) to be used to encrypt the snapshot. If you do not specify a CMK, the default AWS managed CMK is used.

      If you specify a ParentSnapshotId, omit this parameter; the snapshot will be encrypted using the same CMK that was used to encrypt the parent snapshot.

      If Encrypted is set to true, you must specify a CMK ARN.

    • Timeout — (Integer)

      The amount of time (in minutes) after which the snapshot is automatically cancelled if:

      • No blocks are written to the snapshot.

      • The snapshot is not completed after writing the last block of data.

      If no value is specified, the timeout defaults to 60 minutes.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • Description — (String)

        The description of the snapshot.

      • SnapshotId — (String)

        The ID of the snapshot.

      • OwnerId — (String)

        The AWS account ID of the snapshot owner.

      • Status — (String)

        The status of the snapshot.

        Possible values include:
        • "completed"
        • "pending"
        • "error"
      • StartTime — (Date)

        The timestamp when the snapshot was created.

      • VolumeSize — (Integer)

        The size of the volume, in GiB.

      • BlockSize — (Integer)

        The size of the blocks in the snapshot, in bytes.

      • Tags — (Array<map>)

        The tags applied to the snapshot. You can specify up to 50 tags per snapshot. For more information, see Tagging your Amazon EC2 resources in the Amazon Elastic Compute Cloud User Guide.

        • Key — (String)

          The key of the tag.

        • Value — (String)

          The value of the tag.

      • ParentSnapshotId — (String)

        The ID of the parent snapshot.

      • KmsKeyArn — (String)

        The Amazon Resource Name (ARN) of the AWS Key Management Service (AWS KMS) customer master key (CMK) used to encrypt the snapshot.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.
