After you set the source and target locations there are literally dozens of options including whether the target is a mirror or synched folder, when operations should be performed (real time or scheduled), who can do them, how overwrites are handled, how long logs are kept, etc. The large array of settings can lead to a bit of sensory overload, till you get up to speed. Fortunately, the program is for the most part logically laid out, and tool tips pop up over every option with a concise explanation of what it is or does.
IBM's simpler-to-configure Tivoli CDP is only a couple of bucks more and probably a better fit for the average user. But MirrorFolder's extreme configurability and advanced options such as copying folder user permissions make it a must-have for anyone who wants to do complex real time backup.
