Amazonka.EBS
Description
Derived from API version 2019-11-02 of the AWS service descriptions, licensed under Apache 2.0.
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.

Service Configuration
defaultService :: Service Source #
API version 2019-11-02 of the Amazon Elastic Block Store SDK configuration.
Errors
Error matchers are designed for use with the functions provided by
Control.Exception.Lens.
This allows catching (and rethrowing) service specific errors returned
by EBS.
ValidationException
_ValidationException :: AsError a => Getting (First ServiceError) a ServiceError Source #
The input fails to satisfy the constraints of the EBS direct APIs.
AccessDeniedException
_AccessDeniedException :: AsError a => Getting (First ServiceError) a ServiceError Source #
You do not have sufficient access to perform this action.
ConflictException
_ConflictException :: AsError a => Getting (First ServiceError) a ServiceError Source #
The request uses the same client token as a previous, but non-identical request.
ServiceQuotaExceededException
_ServiceQuotaExceededException :: AsError a => Getting (First ServiceError) a ServiceError Source #
Your current service quotas do not allow you to perform this action.
ConcurrentLimitExceededException
_ConcurrentLimitExceededException :: AsError a => Getting (First ServiceError) a ServiceError Source #
You have reached the limit for concurrent API requests. For more information, see Optimizing performance of the EBS direct APIs in the Amazon Elastic Compute Cloud User Guide.
RequestThrottledException
_RequestThrottledException :: AsError a => Getting (First ServiceError) a ServiceError Source #
The number of API requests has exceed the maximum allowed API request throttling limit.
InternalServerException
_InternalServerException :: AsError a => Getting (First ServiceError) a ServiceError Source #
An internal error has occurred.
ResourceNotFoundException
_ResourceNotFoundException :: AsError a => Getting (First ServiceError) a ServiceError Source #
The specified resource does not exist.
Waiters
Waiters poll by repeatedly sending a request until some remote success condition
configured by the Wait specification is fulfilled. The Wait specification
determines how many attempts should be made, in addition to delay and retry strategies.
Operations
Some AWS operations return results that are incomplete and require subsequent
requests in order to obtain the entire result set. The process of sending
subsequent requests to continue where a previous request left off is called
pagination. For example, the ListObjects operation of Amazon S3 returns up to
1000 objects at a time, and you must send subsequent requests with the
appropriate Marker in order to retrieve the next page of results.
Operations that have an AWSPager instance can transparently perform subsequent
requests, correctly setting Markers and other request facets to iterate through
the entire result set of a truncated API operation. Operations which support
this have an additional note in the documentation.
Many operations have the ability to filter results on the server side. See the individual operation parameters for details.
StartSnapshot
data StartSnapshot Source #
See: newStartSnapshot smart constructor.
Constructors
| StartSnapshot' (Maybe (Sensitive Text)) (Maybe Text) (Maybe Bool) (Maybe Text) (Maybe Natural) (Maybe Text) (Maybe [Tag]) Natural |
Instances
Arguments
| :: Natural | |
| -> StartSnapshot |
Create a value of StartSnapshot with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:kmsKeyArn:StartSnapshot', startSnapshot_kmsKeyArn - The Amazon Resource Name (ARN) of the Key Management Service (KMS) key
to be used to encrypt the snapshot. If you do not specify a KMS key, the
default Amazon Web Services managed KMS key is used.
If you specify a ParentSnapshotId, omit this parameter; the snapshot will be encrypted using the same KMS key that was used to encrypt the parent snapshot.
If Encrypted is set to true, you must specify a KMS key ARN.
$sel:clientToken:StartSnapshot', startSnapshot_clientToken - 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 Amazon Web Services SDK.
For more information, see Idempotency for StartSnapshot API in the Amazon Elastic Compute Cloud User Guide.
$sel:encrypted:StartSnapshot', startSnapshot_encrypted - 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 KMS key
specified using the KmsKeyArn parameter. If no value is specified
for KmsKeyArn, the default KMS key for your account is used. If no
default KMS key has been specified for your account, the Amazon Web
Services managed KMS key is used. To set a default KMS key 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.
$sel:parentSnapshotId:StartSnapshot', startSnapshot_parentSnapshotId - 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.
$sel:timeout:StartSnapshot', startSnapshot_timeout - 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.
$sel:description:StartSnapshot', startSnapshot_description - A description for the snapshot.
$sel:tags:StartSnapshot', startSnapshot_tags - The tags to apply to the snapshot.
$sel:volumeSize:StartSnapshot', startSnapshot_volumeSize - The size of the volume, in GiB. The maximum size is 65536 GiB (64
TiB).

$sel:snapshotId:PutSnapshotBlock', putSnapshotBlock_snapshotId - The ID of the snapshot.
$sel:blockIndex:PutSnapshotBlock', putSnapshotBlock_blockIndex - 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. To identify the block
index, divide the logical offset of the data in the logical volume by
the block size (logical offset of data/524288). The logical offset of
the data must be 512 KiB aligned.
$sel:dataLength:PutSnapshotBlock', putSnapshotBlock_dataLength - The size of the data to write to the block, in bytes. Currently, the
only supported size is 524288 bytes.
Valid values: 524288
$sel:checksum:PutSnapshotBlock', putSnapshotBlock_checksum - A Base64-encoded SHA256 checksum of the data. Only SHA256 checksums are
supported.

supported algorithm is SHA256.
$sel:blockData:PutSnapshotBlock', putSnapshotBlock_blockData - The data to write to the block.
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.
