摘要
数据备份是容灾的基础。本文提出了一种基于FC组播服务的远程数据备份方法,对其工作原理和所涉及到的粗波分复用和流量控制等关键技术进行了研究,对基于FC组播的数据备份系统的性能和所属的容灾层次等内容进行了分析。
Backup is the basis of Disaster Recovery(DR) . A new method based on multicast of Fibre Channel to backup data to remote sites is proposed and key technology including CWDM(Coarse Wave Dense Multiplexing) and flow control is analyzed. Meanwhile, it's performance and hierarchie of DR are studied.
