This article introduces the classification of disaster recovery levels for power information systems and a framework for business continuity construction. Through comprehensive risk analysis and evaluation of the impact on business continuity, recovery capability assessment and disaster recovery strategies were formulated, followed by planning and designing disaster recovery plans and developing business continuity plans. In order to improve the disaster recovery capability of information systems and ensure production safety and stability, the post-disaster recovery effect of power information systems was studied in depth. The power information system disaster recovery plan can effectively ensure production continuity and stability. By using appropriate disaster recovery plans and technical means, highly reliable and continuous information systems can be achieved to ensure smooth operation of enterprises and provide important support for enterprise production.
