type Script struct {

	// The SSM document that includes the pre and/or post scripts to run.
	//   - If you are automating VSS backups, specify AWS_VSS_BACKUP . In this case,

	//   SSM document.
	//   - If you are automating application-consistent snapshots for SAP HANA
	//   workloads, specify AWSSystemsManagerSAP-CreateDLMSnapshotForSAPHANA .
	//   - If you are using a custom SSM document that you own, specify either the
	//   name or ARN of the SSM document. If you are using a custom SSM document that is
	//   shared with you, specify the ARN of the SSM document.
	//
	// This member is required.
	ExecutionHandler *string

	// Indicates whether Amazon Data Lifecycle Manager should default to

	//   - To skip the instance for snapshot creation if the pre script fails, specify
	//   false .
	// This parameter is supported only if you run a pre script. If you run a post
	// script only, omit this parameter. Default: true

	//   - If you are using custom SSM documents or automating application-consistent
	//   snapshots of SAP HANA workloads, specify AWS_SYSTEMS_MANAGER .

	ExecutionHandlerService ExecutionHandlerServiceValues

	// Specifies a timeout period, in seconds, after which Amazon Data Lifecycle
	// Manager fails the script run attempt if it has not completed. If a script does
	// not complete within its timeout period, Amazon Data Lifecycle Manager fails the
	// attempt. The timeout period applies to the pre and post scripts individually. If

	ExecutionTimeout *int32

	//   - If the post script fails, Amazon Data Lifecycle Manager retries the post
	//   script only; in this case, the pre script will have completed and the snapshot

	//   Manager calls the SSM document with the pre-script parameter before initiating
	//   snapshot creation.
	//   - To run a post script only, specify POST . In this case, Amazon Data
	//   Lifecycle Manager calls the SSM document with the post-script parameter after
	//   initiating snapshot creation.
	//   - To run both pre and post scripts, specify both PRE and POST . In this case,
	//   Amazon Data Lifecycle Manager calls the SSM document with the pre-script
	//   parameter before initiating snapshot creation, and then it calls the SSM
	//   document again with the post-script parameter after initiating snapshot
	//   creation.
