You can use the Amazon Elastic Block Store (Amazon EBS) direct APIs to create Amazon 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 Amazon 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 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 snapshot during a disaster. Then after recovery, you can restore it back to Amazon Web Services 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 Amazon EBS Snapshot  in the Amazon Elastic Compute Cloud User Guide. For more information about the supported Amazon Web Services Regions, endpoints, and service quotas for the EBS direct APIs, see Amazon Elastic Block Store Endpoints and Quotas  in the Amazon Web Services General Reference.

EBSClient Operations

Command
Summary
CompleteSnapshotCommand

Seals and completes the snapshot after all of the required blocks of data have been written to it. Completing the snapshot changes the status to completed. You cannot write new blocks to a snapshot after it has been completed.

You should always retry requests that receive server (5xx) error responses, and ThrottlingException and RequestThrottledException client error responses. For more information see Error retries  in the Amazon Elastic Compute Cloud User Guide.

GetSnapshotBlockCommand

Returns the data in a block in an Amazon Elastic Block Store snapshot.

You should always retry requests that receive server (5xx) error responses, and ThrottlingException and RequestThrottledException client error responses. For more information see Error retries  in the Amazon Elastic Compute Cloud User Guide.

ListChangedBlocksCommand

Returns information about the blocks that are different between two Amazon Elastic Block Store snapshots of the same volume/snapshot lineage.

You should always retry requests that receive server (5xx) error responses, and ThrottlingException and RequestThrottledException client error responses. For more information see Error retries  in the Amazon Elastic Compute Cloud User Guide.

ListSnapshotBlocksCommand

Returns information about the blocks in an Amazon Elastic Block Store snapshot.

You should always retry requests that receive server (5xx) error responses, and ThrottlingException and RequestThrottledException client error responses. For more information see Error retries  in the Amazon Elastic Compute Cloud User Guide.

PutSnapshotBlockCommand

Writes a block of data to a snapshot. If the specified block contains data, the existing data is overwritten. The target snapshot must be in the pending state.

Data written to a snapshot must be aligned with 512-KiB sectors.

You should always retry requests that receive server (5xx) error responses, and ThrottlingException and RequestThrottledException client error responses. For more information see Error retries  in the Amazon Elastic Compute Cloud User Guide.

StartSnapshotCommand

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.

You should always retry requests that receive server (5xx) error responses, and ThrottlingException and RequestThrottledException client error responses. For more information see Error retries  in the Amazon Elastic Compute Cloud User Guide.

EBSClient Configuration

Parameter
Type
Description
defaultsMode
Optional
DefaultsMode | Provider<DefaultsMode>
The @smithy/smithy-client#DefaultsMode that will be used to determine how certain default configuration options are resolved in the SDK.
disableHostPrefix
Optional
boolean
Disable dynamically changing the endpoint of the client based on the hostPrefix trait of an operation.
extensions
Optional
RuntimeExtension[]
Optional extensions
logger
Optional
Logger
Optional logger for logging debug/info/warn/error.
maxAttempts
Optional
number | Provider<number>
Value for how many times a request will be made at most in case of retry.
profile
Optional
string
Setting a client profile is similar to setting a value for the AWS_PROFILE environment variable. Setting a profile on a client in code only affects the single client instance, unlike AWS_PROFILE.When set, and only for environments where an AWS configuration file exists, fields configurable by this file will be retrieved from the specified profile within that file. Conflicting code configuration and environment variables will still have higher priority.For client credential resolution that involves checking the AWS configuration file, the client's profile (this value) will be used unless a different profile is set in the credential provider options.
region
Optional
string | Provider<string>
The AWS region to which this client will send requests
requestHandler
Optional
__HttpHandlerUserInput
The HTTP handler to use or its constructor options. Fetch in browser and Https in Nodejs.
retryMode
Optional
string | Provider<string>
Specifies which retry algorithm to use.
useDualstackEndpoint
Optional
boolean | Provider<boolean>
Enables IPv6/IPv4 dualstack endpoint.
useFipsEndpoint
Optional
boolean | Provider<boolean>
Enables FIPS compatible endpoints.
