摘　　要：随着医院信息化建设的不断深入,所产生的医疗数据量也越来越大,数据类型也越来越复杂,数据安全成为了现代医院信息系统安全的重中之重,如何构建一个统一、高效、安全可靠的存储管理体系,已成为当前医院信息化建设推进过程中亟须解决的重要问题。在对医疗数据存储研究的基础上,提出了基于虚拟化的容灾备份设计理念,通过采用虚拟化和块级数据同步引擎等先进技术,建立了无中断、零数据丢失的层次化容灾备份管理系统。通过建设虚拟化容灾备份系统,信息系统稳定性、可靠性得到了显著提升,实现了业务连续性保护。结论:基于虚拟化容灾备份系统的建设,最终实现了医疗数据的远程实时备份、信息系统的无中断运行及数据零丢失,保障了医院业务的正常开展。Objective： With the further development of hospital information construction, the amount of medical data is more and more increasing,and type of the medical data is more and more complex. Data security has become a top priority for modern hospital information system. How to build auniform, efficient, safe and reliable storage management systembecomes a problem to be solved imperatively in the current improvement of hospital information construction. Methods： Based on the study of the medical data sto- rage, this paper puts forward the design concept of virtualization-baseddisaster recovery. By adoptingsuchadvanced technology as- virtualization, block-level data synchronization engine and so on, it establishes anuninterrupted, zero data lossand hierarchical disas- ter recoverymanagement system. Results： By establishing the disaster recoverymanagement system, the stability andreliability of hospitalinformation system is improved significantly and assures the continuity of hospitals＇ operation. Conclusion：The constructio- nor virtualization-based disaster recovery management systemrealizes the real-time distance backup of medical data, uninterruptedo- oeration of hospital information system and zero data loss. It guarantees the normal operation of the medical services.
