Abstract
An application level disaster recovery system is designed and implemented in this paper. The method of modular design is adopted by this system, multi-strategy backup and recovery of data is used to protect the integrity and high-availability of data. Data replication ensures the data consistency between the primary and backup system. When disaster happens, business continuity is maintained by switching the services, so the disaster recovery of application level is achieved.
