Research and Implementation on Remote Disaster Recovery System

Most of the current disaster recovery solutions need to rely on expensive commercial disaster recovery software and hardware. In order to reduce the cost of disaster recovery, a fully featured, affordable disaster recovery solution and an offsite disaster recovery system RDRS (Remote Disaster Recovery System) are putted forward in this paper. Based on existing technologies, such as DFS, database mirroring and IP address drifting, the RDRS is completed without introducing expensive commercial disaster recovery software and hard-ware. Tentative results show that, facing varieties of failures, this solution and the RDRS can effectively conduct disaster recovery. In General, this solution and system are fully able to meet the requirements for most disaster recovery project plan, low-cost and strong-security.
