Ways to Schedule Rman backups
Personally I would schule it using the Windows Scheduler. You might want to get robocopy if you are copying your backup files to another server. Having an email client that you can send emails from DOS can be helpful. But otherwise you would just write .BAT files and or a Powershell file. You want a process that creates a backup log and checks that log for errors. Then you can send out emails when there are errors. There should be something already written online somewhere.
