ABSTRACT:
Techniques are described for replicating data from one to one or more heterogeneous data processing or communication devices for the purpose of remote backup, redundancy, content distribution, communications, observations or measurements. In a first phase, the attributes of the data that are modified or created on a device or that are passing through the device are tracked and journaled in volatile or non-volatile storage in real-time. In a second phase, the attributes that match patterns pre-specified in a configuration are used to determine which data to replicate and which modifications to make the devices. In a third phase, the data is replicated. In a preferred embodiment, the described techniques comprise an application that runs on a host device or is embedded in a logic or memory device. The described invention is designed to be transparent for system redundancy and error recovery processes such as error correction, re-transmission on links, and raid configuration.
