Abstract: The disclosed embodiments relate to a system/process which can be used to provide redundancy and error/failure recovery to a System of Record (SOR), such as an electronic financial transaction processing system or sub-system thereof, which processes transactions received from one or more sources and generates results/outputs based thereon for communication to one or more recipients/destinations/consumers. The disclosed embodiments minimize, if not eliminate, both the amount of data, i.e., the number of transactions, which can be lost during a failure and the performance impact on the SOR. Generally, the disclosed embodiments are implemented so as to receive/intercept each incoming transaction communicated to the primary instance prior to receipt thereby and intercept or otherwise regulate the communication of the outputs of the primary instance, generated based on the primary instance's processing of the incoming transactions, to the destinations/recipients/consumers thereof.
