A service recovery mechanism by recovering service´s data

Service recovery technology is an important constituent part of the emergency response technologies. The service recovery goal is to build a technology system of service recovery focusing on the survival of information system services. By analyzing the relationship between service and data, we present a service recovery mechanism by recovering service´s data. We introduce a third party service monitor to monitor the state changes of the service, design the data recovery model, and give a example of quick data recovery. At last, we present a prototype system of service recovery; the experiment results toward the prototype system show that the mechanism designed by us can greatly improve the service recovery efficiency and it can meet the timeliness requirements of the information service.
