Overview

An API client for EBS. To construct a client, you need to configure a :region and :credentials.

client = Aws::EBS::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the developer guide.

See #initialize for a full list of supported configuration options.

#initialize(options) ⇒ Client

Returns a new instance of Client.

Parameters:

  • options (Hash)

Options Hash (options):

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials. This can be an instance of any one of the following classes:

    • Aws::Credentials - Used for configuring static, non-refreshing credentials.

    • Aws::InstanceProfileCredentials - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • Aws::SharedCredentials - Used for loading credentials from a shared file, such as ~/.aws/config.

    • Aws::AssumeRoleCredentials - Used when you need to assume a role.

    When :credentials are not configured directly, the following locations will be searched for credentials:

    • Aws.config[:credentials]
    • The :access_key_id, :secret_access_key, and :session_token options.
    • ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    • ~/.aws/credentials

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

Examples:

Request syntax with placeholder values


resp = client.put_snapshot_block({
  snapshot_id: "SnapshotId", # required

  checksum: "Checksum", # required
  checksum_algorithm: "SHA256", # required, accepts SHA256
})

Response structure


resp.checksum #=> String
resp.checksum_algorithm #=> String, one of "SHA256"

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :snapshot_id (required, String) —

    The ID of the snapshot.

  • :block_index (required, Integer) —

    The block index of the block in which to write the data. A block index is the offset position of a block within a snapshot, and it is used to identify the block. To identify the logical offset of the data in the logical volume, multiply the block index with the block size (Block index * 512 bytes).

  • :block_data (required, String, IO) —

    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.

  • :data_length (required, 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 (required, String) —

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

  • :checksum_algorithm (required, String) —

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

#start_snapshot(params = {}) ⇒ Types::StartSnapshotResponse

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.

Examples:

Request syntax with placeholder values


resp = client.start_snapshot({
  volume_size: 1, # required
  parent_snapshot_id: "SnapshotId",
  tags: [
    {
      key: "TagKey",
      value: "TagValue",
    },
  ],
  description: "Description",
  client_token: "IdempotencyToken",
  encrypted: false,
  kms_key_arn: "KmsKeyArn",
  timeout: 1,
})

Response structure


resp.description #=> String
resp.snapshot_id #=> String
resp.owner_id #=> String
resp.status #=> String, one of "completed", "pending", "error"
resp.start_time #=> Time
resp.volume_size #=> Integer
resp.block_size #=> Integer
resp.tags #=> Array
resp.tags[0].key #=> String
resp.tags[0].value #=> String
resp.parent_snapshot_id #=> String
resp.kms_key_arn #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :volume_size (required, Integer) —

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

  • :parent_snapshot_id (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<Types::Tag>) —

    The tags to apply to the snapshot.

  • :description (String) —

    A description for the snapshot.

  • :client_token (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.

    A suitable default value is auto-generated. You should normally not need to pass this option.**

  • :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.

  • :kms_key_arn (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.

Returns:
