We present a simple and efficient algorithm to record a global snapshot of a distributed system, where all messages are sent and delivered in causal order. For a system with N processes, the algorithm requires N control messages to record a distributed snapshot of the system. It is shown that the snapshot recorded represents a consistent global state of the system.
