摘要
针对一种远程容灾系统,设计并实现了应用服务在本地服务器与远程服务器的漂移方法。服务漂移功能模块分为三个部分,分别位于灾备中心、远程服务器和本地网关上。灾备中心负责建立起本地服务器的数据镜像的逻辑卷,将其挂载至远程服务器。本地网关再把对本地服务器的访问重定向至远程服务器。实验结果证明,通过服务漂移实现了远程服务器代替本地服务器向外界提供服务,恢复了应用的业务连续性,实现了应用级别的容灾。
Toward the remote disaster recovery system, a method of switching application service between local and remote server, namely, service drift, is designed and implemented in this paper. Service drift include three function parts： Disaster Recovery Center, remote server and local gateway. The Disaster Recovery Center builds up a mirror image of local server’s data on the logical volume, and then mounts the logical volume on remote server. Local gateway redirects the accessing local server to remote server. The result of experiments proves ： service drift help the remote server replace the local server to offer continual service, so business is maintained, and the disaster recovery of application level is achieved.
