%X <p>Focused on the issue that it is hard to quantify and evaluate a disaster tolerant information system, a general modeling method for the disaster tolerant information system was proposed. A disaster tolerant simulation system (DTSS) was designed and implemented. A general disaster tolerant simulation system model was put forward upon three-tier network architecture model, and fault injection technology was made to simulate the disaster events. Furthermore, system business simulation is carried with script programming. Simulation consistency, recovery time object, recovery point object and available storage indices were designed to evaluate the system. It is shown that the disaster tolerant simulation system can provide data service for disaster system construction of the information system, disaster recovery ability evaluation of the disaster tolerant information system, the system maintenance.</p>
