传递Windows服务参数以使其执行操作

I want to turn a program I have into a service so I can use it without logging it. Basically what it does is it backs up specified folders to a specified location using SSH. However the problem I'm running into is I don't know how to tell it these items. I only know how to start, stop, and run a custom command with only an integer with a parameter.I want to turn a program I have into a service
