We consider an external recovery problem, where a system is divided into autonomous subsystems which can be recovered only by the means of logging the messages exchanged between the subsystems. The question follows: what restrictions to the subsystem's autonomy are required to make the external recovery possible? We present example solutions affecting different aspects of system's independence.
