 @param [Hash] options ({})
 @option options [required, String] :db_cluster_identifier
   The name of the new DB cluster to be created.

   Constraints:

   * Must contain from 1 to 63 letters, numbers, or hyphens

   * First character must be a letter

   * Can't end with a hyphen or contain two consecutive hyphens
 @option options [String] :restore_type
   The type of restore to be performed. You can specify one of the
   following values:

   * `full-copy` - The new DB cluster is restored as a full copy of the
     source DB cluster.

   * `copy-on-write` - The new DB cluster is restored as a clone of the
     source DB cluster.

   Constraints: You can't specify `copy-on-write` if the engine version
   of the source DB cluster is earlier than 1.11.

   If you don't specify a `RestoreType` value, then the new DB cluster
   is restored as a full copy of the source DB cluster.
 @option options [Time,DateTime,Date,Integer,String] :restore_to_time
   The date and time to restore the DB cluster to.

   Valid Values: Value must be a time in Universal Coordinated Time (UTC)
   format

   Constraints:

   * Must be before the latest restorable time for the DB instance

   * Must be specified if `UseLatestRestorableTime` parameter is not
     provided

   * Can't be specified if `UseLatestRestorableTime` parameter is true

   * Can't be specified if `RestoreType` parameter is `copy-on-write`

   Example: `2015-03-07T23:45:00Z`
 @option options [Boolean] :use_latest_restorable_time
   A value that is set to `true` to restore the DB cluster to the latest
   restorable backup time, and `false` otherwise.

   Default: `false`

   Constraints: Can't be specified if `RestoreToTime` parameter is
   provided.
 @option options [Integer] :port
   The port number on which the new DB cluster accepts connections.

   Constraints: A value from `1150-65535`.

   Default: The default port for the engine.
 @option options [String] :db_subnet_group_name
   The DB subnet group name to use for the new DB cluster.

   Constraints: If supplied, must match the name of an existing
   DBSubnetGroup.

   Example: `mySubnetgroup`
 @option options [String] :option_group_name
   The name of the option group for the new DB cluster.
 @option options [Array<String>] :vpc_security_group_ids
   A list of VPC security groups that the new DB cluster belongs to.
 @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.*

 @option options [String] :kms_key_id
   The AWS KMS key identifier to use when restoring an encrypted DB
   cluster from an encrypted DB cluster.

   The KMS key identifier is the Amazon Resource Name (ARN) for the KMS
   encryption key. If you are restoring a DB cluster with the same AWS
   account that owns the KMS encryption key used to encrypt the new DB
   cluster, then you can use the KMS key alias instead of the ARN for the
   KMS encryption key.

   You can restore to a new DB cluster and encrypt the new DB cluster
   with a KMS key that is different than the KMS key used to encrypt the
   source DB cluster. The new DB cluster is encrypted with the KMS key
   identified by the `KmsKeyId` parameter.

   If you don't specify a value for the `KmsKeyId` parameter, then the
   following occurs:

   * If the DB cluster is encrypted, then the restored DB cluster is
     encrypted using the KMS key that was used to encrypt the source DB
     cluster.

   * If the DB cluster is not encrypted, then the restored DB cluster is
     not encrypted.

   If `DBClusterIdentifier` refers to a DB cluster that is not encrypted,
   then the restore request is rejected.
 @option options [Boolean] :enable_iam_database_authentication
   True to enable mapping of AWS Identity and Access Management (IAM)
   accounts to database accounts, and otherwise false.

   Default: `false`
 @option options [Integer] :backtrack_window
   The target backtrack window, in seconds. To disable backtracking, set
   this value to 0.

   Default: 0

   Constraints:

   * If specified, this value must be set to a number from 0 to 259,200
     (72 hours).

   ^
 @option options [Array<String>] :enable_cloudwatch_logs_exports
   The list of logs that the restored DB cluster is to export to
   CloudWatch Logs. The values in the list depend on the DB engine being
   used. For more information, see [Publishing Database Logs to Amazon
   CloudWatch Logs][1] in the *Amazon Aurora User Guide*.



   [1]: https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/USER_LogAccess.html#USER_LogAccess.Procedural.UploadtoCloudWatch
 @option options [String] :db_cluster_parameter_group_name
   The name of the DB cluster parameter group to associate with this DB
   cluster. If this argument is omitted, the default DB cluster parameter
   group for the specified engine is used.

   Constraints:

   * If supplied, must match the name of an existing DB cluster parameter
     group.

   * Must be 1 to 255 letters, numbers, or hyphens.

   * First character must be a letter.

   * Can't end with a hyphen or contain two consecutive hyphens.
 @option options [Boolean] :deletion_protection
   Indicates if the DB cluster should have deletion protection enabled.
   The database can't be deleted when this value is set to true. The
   default is false.
 @option options [Boolean] :copy_tags_to_snapshot
   True to copy all tags from the restored DB cluster to snapshots of the
   restored DB cluster, and otherwise false. The default is false.
 @return [DBCluster]
