> - Daily—The job is executed once a day.
> - Weekly—The job is executed once a week.
> - Monthly—The job is executed once a month.
> - Delta—The job is executed beginning at the specified start time and thereafter at user-specified intervals (days:hours:minutes).
> - One-time mode—The job is executed once at a user-specified time.
