摘　　要：VMware的虚拟机文件系统是一个强大的自动化文件系统,它简化了虚拟机相关的存储空间管理。文章旨在利用VMFS卷机制为虚拟机容灾提供一种有效的解决方法,首先介绍VMFS的特点,然后阐述了VMFS的工作原理,最后给出存储设备的快照与VMFS卷机制相结合实现虚拟机备份与容灾的方法。该方案不但可以减少第三方软件购置成本,而且也降低了生产服务器备份时的负载。The VMware Virtual Machine File System （VMFS） is a powerful automatic file system that simplifies the storage management for virtual machines. This paper aims to use the mechanism of VMFS volume to provide an effective disaster recovery solution for virtual machines. It firstly introduces the characteristics of VMFS, illustrates the working principles of VMFS, and finally proposes a method of combining the storage device snapshot mechanism and VMFS volume mechanism to accomplish the backup and disaster recovery for virtual machines. In this way it can not only cut down the acquisition cost of the third-party software, but also reduce the backup load of the production server.
