Is there a way to work with Git on the FME Server to easy rollback to another version?

 

On slide 24 is something mentioned:

 

http://de.slideshare.net/SafeSoftware/implementing-a-simple-web-application-with-fme-server

 

"Allows workspaces to be shared with confidence, placed under source control (e.g. Git), and configured externally"

 

 

Or what is a good workflow in context with FME Server to not disturb a productive system and develop/change stuff in the workspaces?

 

Is there a tutorial/best practice paper or video? Or what are your experiences?
