	//
	// Constraints:

	//   - Must specify a valid system snapshot in the "available" state.
	//
	// Example: rds:mydb-2012-04-02-00-01

	//

	//
	//   - Can't end with a hyphen or contain two consecutive hyphens
	//
	// Example: my-db-snapshot
	//
	// This member is required.
	TargetDBSnapshotIdentifier *string

	// Specifies whether to copy the DB option group associated with the source DB
	// snapshot to the target Amazon Web Services account and associate with the target
	// DB snapshot. The associated option group can be copied only with cross-account
	// snapshot copy calls.
	CopyOptionGroup *bool

	// Specifies whether to copy all tags from the source DB snapshot to the target DB
	// snapshot. By default, tags aren't copied.
	CopyTags *bool

	// The Amazon Web Services KMS key identifier for an encrypted DB snapshot. The
	// Amazon Web Services KMS key identifier is the key ARN, key ID, alias ARN, or
	// alias name for the KMS key.
	//
	// If you copy an encrypted DB snapshot from your Amazon Web Services account, you
	// can specify a value for this parameter to encrypt the copy with a new KMS key.
	// If you don't specify a value for this parameter, then the copy of the DB
	// snapshot is encrypted with the same Amazon Web Services KMS key as the source DB
	// snapshot.
	//
	// If you copy an encrypted DB snapshot that is shared from another Amazon Web
	// Services 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 Amazon Web Services Region,
	// then you must specify an Amazon Web Services KMS key identifier for the
	// destination Amazon Web Services Region. KMS keys are specific to the Amazon Web
	// Services Region that they are created in, and you can't use KMS keys from one
	// Amazon Web Services Region in another Amazon Web Services Region.
	KmsKeyId *string

	// 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 Amazon Web Services
	// 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 Amazon Web Services
	// Regions. For more information, see [Option group considerations]in the Amazon RDS User Guide.
	//
	// [Option group considerations]: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_CopySnapshot.html#USER_CopySnapshot.Options
	OptionGroupName *string

	// When you are copying a snapshot from one Amazon Web Services GovCloud (US)
	// Region to another, the URL that contains a Signature Version 4 signed request
	// for the CopyDBSnapshot API operation in the source Amazon Web Services Region
	// that contains the source DB snapshot to copy.
	//
	// This setting applies only to Amazon Web Services GovCloud (US) Regions. It's
	// ignored in other Amazon Web Services Regions.
	//
	// You must specify this parameter when you copy an encrypted DB snapshot from
	// another Amazon Web Services Region by using the Amazon RDS API. Don't specify
	// PreSignedUrl when you are copying an encrypted DB snapshot in the same Amazon
	// Web Services Region.
	//
	// The presigned URL must be a valid request for the CopyDBClusterSnapshot API
	// operation that can run in the source Amazon Web Services Region that contains
	// the encrypted DB cluster snapshot to copy. The presigned URL request must
	// contain the following parameter values:
	//
	//   - DestinationRegion - The Amazon Web Services Region that the encrypted DB
	//   snapshot is copied to. This Amazon Web Services Region is the same one where the
	//   CopyDBSnapshot operation is called that contains this presigned URL.
	//
	// For example, if you copy an encrypted DB snapshot from the us-west-2 Amazon Web
	//   Services Region to the us-east-1 Amazon Web Services Region, then you call the
	//   CopyDBSnapshot operation in the us-east-1 Amazon Web Services Region and
	//   provide a presigned URL that contains a call to the CopyDBSnapshot operation
	//   in the us-west-2 Amazon Web Services Region. For this example, the
	//   DestinationRegion in the presigned URL must be set to the us-east-1 Amazon Web
	//   Services Region.
	//
	//   - KmsKeyId - The KMS key identifier for the KMS key to use to encrypt the copy
	//   of the DB snapshot in the destination Amazon Web Services Region. This is the
	//   same identifier for both the CopyDBSnapshot operation that is called in the
	//   destination Amazon Web Services Region, and the operation 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 Amazon Web Services Region. For example, if you are
	//   copying an encrypted DB snapshot from the us-west-2 Amazon Web Services Region,
	//   then your SourceDBSnapshotIdentifier looks like the following example:
	//   arn:aws:rds:us-west-2:123456789012:snapshot:mysql-instance1-snapshot-20161115 .
	//
	// To learn how to generate a Signature Version 4 signed request, see [Authenticating Requests: Using Query Parameters (Amazon Web Services Signature Version 4)] and [Signature Version 4 Signing Process].
	//
	// If you are using an Amazon Web Services SDK tool or the CLI, you can specify
	// SourceRegion (or --source-region for the CLI) instead of specifying PreSignedUrl
	// manually. Specifying SourceRegion autogenerates a presigned URL that is a valid
	// request for the operation that can run in the source Amazon Web Services Region.

	// [Signature Version 4 Signing Process]: https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html
	PreSignedUrl *string

	// The AWS region the resource is in. The presigned URL will be created with this
	// region, if the PresignURL member is empty set.
	SourceRegion *string

	// A list of tags. For more information, see [Tagging Amazon RDS Resources] in the Amazon RDS User Guide.
	//
	// [Tagging Amazon RDS Resources]: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Tagging.html
	Tags []types.Tag

	// The external custom Availability Zone (CAZ) identifier for the target CAZ.
	//
	// Example: rds-caz-aiqhTgQv .
