Hello tarikk ,
you can achieve this on policy level or on script level. I personally have an experience with policy config. The principle is that you must create overlapping pairs of automatic+application schedules. So for example:
Application Backup schedule for usual daily backups: Mo-Fr 0-24
Automatic schedule for daily backups: Mo-Fr 20-24
Application Backup schedule for usual Monthly backups: Sa 8-12
Automatic schedule for Monthly backups: Sa 8-11
Yearly schedules on Sundays or Saturday afternoons etc.
So automatic schedule runs picks-up a correct application schedule which is the only appl schedule opened at that time.
However this design is not working well for manual / SAP initiated backups.
