摘要
SAN存储备份的高可用性要求在进行文件系统备份时不能停止文件系统访问服务,那么SAN存储下的文件系统备份软件就需要解决基本备份操作与文件系统数据访问之间的同步控制和联动。文章基于SAN的两种典型的备份技术:复制技术和快照技术,提出了UNIX文件系统的SAN备份的解决方案。
In order to achieve high availability, in the course of file system backup,file system access service must not be ceased. So, it is necessary to solve the problem of synchronous control between server's file system backup and data access to files. This paper provides a solution to backup UNIX file system applying two typical techniques, Replication and Snapshot, based on SAN.
