Embodiments of the system described herein can be implemented in a software application that runs on a host device or is embedded in a logic or memory device such as a gate array, EEPROM, a control, or dynamical system. The system embodiment allows a set of similar or dissimilar intelligent devices or sensors, which may be interconnected with any type of network or bus, to replicate data between themselves for the purpose of remote backup, redundancy, content distribution, or measurements. The attributes of the data, which may be changed or created on one device or passed through the device, are tracked and journaled in volatile or non-volatile storage in a first phase. This occurs in real-time as the data changes or passes through the device. In a second phase, the attributes that match patterns pre-specified in a configuration are used to decide what changes or the content to replicate to one or more devices. In a third phase, the data is replicated. In practice, the techniques described herein are independent of hardware, operating systems, and applications. The example embodiment is designed to be transparent for system redundancy and error recovery processes such as error correction, retransmission on links, and raid reconfiguration.
