【摘要】 针对传统灾备系统中维护管理难、资源利用率低、可扩展性差等不足,提出了基于虚拟化技术设计灾备系统的思路,分析了服务器虚拟化、网络虚拟化、存储虚拟化等关键技术,研究并设计了以资源池管理为中心,融合需求分析、容灾备份、灾难恢复、灾备演练、灾难预警等环节的灾备系统模型。最后,通过测试验证了虚拟化灾备系统在系统恢复性能上远远好于传统灾备系统。更多还原

【Abstract】 Studying against deficiencies in traditional backup system for disaster recovery such as difficult to maintain and manage,low in resource utilization and scalability,an idea mat design backup system for disaster recovery based on virtualization is emerged.Key technologies such as server virtualization,network virtualization and storage virtualization are analyzed.A backup system model for disaster recovery which is centered on resource pool management with demand analysis,disaster backup,disaster recovery,disaster exercises and disaster warning is studied and designed.Finally,the system recovery performance of virtualization-based backup system for disaster recovery is proved through test to be much better than that of traditional backup system for disaster recovery.更多还原
