摘　　要：本文阐述了云计算数据中心和"双活"的基本概念,从多种角度研究基于云计算的数据中心容灾系统的建设,提出了基于高可用性的本地接管预案、基于"双活"的本异地互备预案、基于备份恢复的数据保护预案和基于数据库复制的系统切换预案,旨在利用各种技术和管理手段将灾难的影响化解。基于云计算的数据中心容灾系统在发生灾难时,能够保证业务的连续性,实现几乎零停机实时迁移。With illustration of the basic concepts of cloud computing and active-active data centers, this paper provided a multiple-perspective research on construction of a cloud-computing-based disaster recovery system. In order to greatly weaken the influence of hazards, a variety of techniques and management approaches were deployed, involving the HA-based （High-Availability-based） local host solution, the active-active-based local and/or remote backup solution, the data-recovery-based solution for data protection and the database-replication-based solution for switchover from one system to another. In the event of a disaster, the cloud-computing-based data center disaster recovery system could guarantee the continuity of the business by migration of the system with almost no breakdown.
