I have a requirement to export data from salesforce on regular basis. and for this: I need to schedule my data export task and i have gone through the Schedule wizard of jitterbit but one thing is not clear, suppose i schedule my task then do i need to run this software for lifetime like everyday or is there any service which triggers this jitterbit so that it can perform its task.
Jitterbit needs a Service to run as well as the Application. You should be able to find the apps: Mac ("Jitterbit Cloud Data Loader Start Services" and "Jitterbit Cloud Data Loader Stop Services") Windows: (StartServices and StopServices) in the Jitterbit Cloud Data Loader folder in Program Files (x86). So long as the Service is running, the Application does not have to be open. If you are worried about the Services stopping, you can use something like Lingon or some combination of Automator and Calendar for the Mac or Task Scheduler or similar for Windows.
