#copy(options = {}) ⇒ Types::CopySnapshotResult

Examples:

Request syntax with placeholder values


snapshot.copy({
  description: "String",
  destination_region: "String",
  encrypted: false,
  kms_key_id: "String",
  presigned_url: "String",
  source_region: "String", # required
  dry_run: false,
})

Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :description (String) —

    A description for the EBS snapshot.

  • :destination_region (String) —

    The destination region to use in the ‘PresignedUrl` parameter of a snapshot copy operation. This parameter is only valid for specifying the destination region in a `PresignedUrl` parameter, where it is required.

    <note markdown=“1”> ‘CopySnapshot` sends the snapshot copy to the regional endpoint that you send the HTTP request to, such as `ec2.us-east-1.amazonaws.com` (in the AWS CLI, this is specified with the `–region` parameter or the default region in your AWS configuration file).

    </note>
  • :encrypted (Boolean) —

    Specifies whether the destination snapshot should be encrypted. You can encrypt a copy of an unencrypted snapshot using this flag, but you cannot use it to create an unencrypted copy from an encrypted snapshot. Your default CMK for EBS is used unless a non-default AWS Key Management Service (AWS KMS) CMK is specified with ‘KmsKeyId`. For more information, see [Amazon EBS Encryption] in the *Amazon Elastic Compute Cloud User Guide*.

    [1]: docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html

  • :kms_key_id (String) —

    The full ARN of the AWS Key Management Service (AWS KMS) CMK to use when creating the snapshot copy. This parameter is only required if you want to use a non-default CMK; if this parameter is not specified, the default CMK for EBS is used. The ARN contains the ‘arn:aws:kms` namespace, followed by the region of the CMK, the AWS account ID of the CMK owner, the `key` namespace, and then the CMK ID. For example, arn:aws:kms:us-east-1:012345678910:key/abcd1234-a123-456a-a12b-a123b4cd56ef. The specified CMK must exist in the region that the snapshot is being copied to. If a `KmsKeyId` is specified, the `Encrypted` flag must also be set.

  • :presigned_url (String) —

    The pre-signed URL that facilitates copying an encrypted snapshot. This parameter is only required when copying an encrypted snapshot with the Amazon EC2 Query API; it is available as an optional parameter in all other cases. The ‘PresignedUrl` should use the snapshot source endpoint, the `CopySnapshot` action, and include the `SourceRegion`, `SourceSnapshotId`, and `DestinationRegion` parameters. The `PresignedUrl` must be signed using AWS Signature Version 4. Because EBS snapshots are stored in Amazon S3, the signing algorithm for this parameter uses the same logic that is described in [Authenticating Requests by Using Query Parameters (AWS Signature Version 4)] in the *Amazon Simple Storage Service API Reference*. An invalid or improperly signed `PresignedUrl` will cause the copy operation to fail asynchronously, and the snapshot will move to an `error` state.

    [1]: docs.aws.amazon.com/AmazonS3/latest/API/sigv4-query-string-auth.html

  • :source_region (required, String) —

    The ID of the region that contains the snapshot to be copied.

  • :dry_run (Boolean) —

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is ‘DryRunOperation`. Otherwise, it is `UnauthorizedOperation`.

Returns:

end

#create_tags(options = {}) ⇒ Tag::Collection

Examples:

Request syntax with placeholder values


tag = snapshot.create_tags({
  dry_run: false,
  tags: [ # required
    {
      key: "String",
      value: "String",
    },
  ],
})

Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :dry_run (Boolean) —

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is ‘DryRunOperation`. Otherwise, it is `UnauthorizedOperation`.

  • :tags (required, Array<Types::Tag>) —

    One or more tags. The ‘value` parameter is required, but if you don’t want the tag to have a value, specify the parameter with no value, and we set the value to an empty string.

end

#data_encryption_key_id ⇒ String

The data encryption key identifier for the snapshot. This value is a unique identifier that corresponds to the data encryption key that was used to encrypt the original volume or snapshot copy. Because data encryption keys are inherited by volumes created from snapshots, and vice versa, if snapshots share the same data encryption key identifier, then they belong to the same volume/snapshot lineage. This parameter is only returned by the DescribeSnapshots API operation.

Returns:

  • (String)
