摘　　要： 本文围绕在线备份和高可用性，详细论述了文件系统在线备份(filesystemonlinebackup——fsobackup)系统的系统结构及系统的设计和实现。主要工作和成果是： 1.设计并实现了高可用性在线备份模块，完成了文件系统的冻结功能、冗余path处理和文件系统的自动挂接、卸载功能； 2.设计并实现了tog和fsobackup系统的集成； With the widespread application and rapid development of the computer science and Internet technology, the expert estimates that the requirement of storage capability would be increased by the rate of 50/%--100/% every year;to lots of corporations, as a result of their work request, the data must be in online state everywhen. So, at the time of available data are extremely increased, how to protect the security, integrity and coherence of the data effectively and how to enhance the high availability in storage management software has become an important target.Storage Area Network/(SAN/) has solved the problems of high availability, security and performance better. SAN has been used in more and more establishment of storage system for its strong points such as easily management, strong expansibility, strong fault tolerant, high availability and so on.As a rapidly developing technology, the storage technology has a very broad market foreground. The author took part in the design and development work of storage management software in SAN environment. Aim to the needs of online backup and high availability, the developers had designed and implemented the File System Online Backup/(FSOBackup/).The thesis discusses the framework, design and implement in detail and focuses on the online backup and high availability. The author's work and achievement are:1. Design and implement the online backup module, and accomplish the freeze function of the file system, the PATH management, the mount and unmount function;2. Design and implement the integration of TOG and FSOBackup system.
