 @param [Hash] options ({})
 @option options [required, String] :target_db_snapshot_identifier
   The identifier for the copy of the snapshot.

   Constraints:

   * Can't be null, empty, or blank

   * Must contain from 1 to 255 letters, numbers, or hyphens

   * First character must be a letter

   * Can't end with a hyphen or contain two consecutive hyphens

   Example: `my-db-snapshot`
 @option options [String] :kms_key_id
   The AWS KMS key ID for an encrypted DB snapshot. The KMS key ID is the
   Amazon Resource Name (ARN), KMS key identifier, or the KMS key alias
   for the KMS encryption key.

   If you copy an encrypted DB snapshot from your AWS account, you can
   specify a value for this parameter to encrypt the copy with a new KMS
   encryption key. If you don't specify a value for this parameter, then
   the copy of the DB snapshot is encrypted with the same KMS key as the
   source DB snapshot.

   If you copy an encrypted DB snapshot that is shared from another AWS
   account, then you must specify a value for this parameter.

   If you specify this parameter when you copy an unencrypted snapshot,
   the copy is encrypted.

   If you copy an encrypted snapshot to a different AWS Region, then you
   must specify a KMS key for the destination AWS Region. KMS encryption
   keys are specific to the AWS Region that they are created in, and you
   can't use encryption keys from one AWS Region in another AWS Region.
 @option options [Array<Types::Tag>] :tags
   A list of tags. For more information, see [Tagging Amazon RDS
   Resources][1] in the *Amazon RDS User Guide.*



   [1]: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Tagging.html
 @option options [Boolean] :copy_tags
   True to copy all tags from the source DB snapshot to the target DB
   snapshot, and otherwise false. The default is false.
 @option options [String] :pre_signed_url
   The URL that contains a Signature Version 4 signed request for the
   `CopyDBSnapshot` API action in the source AWS Region that contains the
   source DB snapshot to copy.

   You must specify this parameter when you copy an encrypted DB snapshot
   from another AWS Region by using the Amazon RDS API. You can specify
   the `--source-region` option instead of this parameter when you copy
   an encrypted DB snapshot from another AWS Region by using the AWS CLI.

   The presigned URL must be a valid request for the `CopyDBSnapshot` API
   action that can be executed in the source AWS Region that contains the
   encrypted DB snapshot to be copied. The presigned URL request must
   contain the following parameter values:

   * `DestinationRegion` - The AWS Region that the encrypted DB snapshot
     is copied to. This AWS Region is the same one where the
     `CopyDBSnapshot` action is called that contains this presigned URL.

     For example, if you copy an encrypted DB snapshot from the us-west-2
     AWS Region to the us-east-1 AWS Region, then you call the
     `CopyDBSnapshot` action in the us-east-1 AWS Region and provide a
     presigned URL that contains a call to the `CopyDBSnapshot` action in
     the us-west-2 AWS Region. For this example, the `DestinationRegion`
     in the presigned URL must be set to the us-east-1 AWS Region.

   * `KmsKeyId` - The AWS KMS key identifier for the key to use to
     encrypt the copy of the DB snapshot in the destination AWS Region.
     This is the same identifier for both the `CopyDBSnapshot` action
     that is called in the destination AWS Region, and the action
     contained in the presigned URL.

   * `SourceDBSnapshotIdentifier` - The DB snapshot identifier for the
     encrypted snapshot to be copied. This identifier must be in the
     Amazon Resource Name (ARN) format for the source AWS Region. For
     example, if you are copying an encrypted DB snapshot from the
     us-west-2 AWS Region, then your `SourceDBSnapshotIdentifier` looks
     like the following example:
     `arn:aws:rds:us-west-2:123456789012:snapshot:mysql-instance1-snapshot-20161115`.

 @option options [String] :option_group_name
   The name of an option group to associate with the copy of the
   snapshot.

   Specify this option if you are copying a snapshot from one AWS Region
   to another, and your DB instance uses a nondefault option group. If
   your source DB instance uses Transparent Data Encryption for Oracle or
   Microsoft SQL Server, you must specify this option when copying across
   AWS Regions. For more information, see [Option Group
   Considerations][1] in the *Amazon RDS User Guide.*

 @option options [String] :destination_region
 @option options [String] :source_region
   The source region of the snapshot. This is only needed when the
   shapshot is encrypted and in a different region.
