At Windows Event Log event
This type of schedule is effective only in Windows operating systems.
You can schedule a backup task to start when a certain Windows event has been recorded in one of
the event logs such as the Application, Security, or System log.
For example, you may want to set up a backup plan that will automatically perform an emergency
full backup of your data as soon as Windows discovers that your hard disk drive is about to fail.
