Question: How can I change the location of the data/backup files from the default c:\RBS to a different drive after the software has been installed.

Answer:

In the Web Console, go to the Monitor screen. Click the button to stop the RBS Server.

Go to the Setup->Properties screen. Change the Server Root Folder. (do this quickly, because the Server may automatically restart)

Go back to the Monitor screen and restart the Server if it hasn't already restarted by itself.
