Construction and Maintenance of Disaster Recovery System

For the requirements of information system construction and maintenance in State Grid, the disaster recovery system is important to protect data safety. From system construction and maintenance perspectives, this paper analyzes applicability of three typical disaster recovery policies, six disaster recovery levels, and the RPO/ RTO value selection methods using system analysis methods. And then the correlation of data backup and data disaster recovery, and the correlation of construction and maintenance are studied respectively. Further, from people, process and tools perspectives, key factors for the disaster recovery system operation and maintenance are summarized, and from management goals, management modes, systems, technology supports perspectives, the methods to construct operation and maintenance system integrated with three key factors are described in detail.
