摘　　要：ReiserFS文件系统是Linux系统下的一种非常优秀的文件系统,同时也是Linux系统上较早的日志文件系统之一。该文件系统有着日志机制先进、磁盘利用率高、搜寻方式快速以及性能高等特点,在需要同时快速处理大型文件和众多的小型文件的系统上得到了较为广泛的使用。目前,国内外对ReiserFS文件系统删除文件的恢复的研究较少,基本没有相关的恢复技术资料。文章在详细分析了该文件系统结构的基础上进行了删除数据恢复的研究,提出了一种ReiserFS删除文件恢复方法,该方法在文件数据没有被覆盖的情况下能够完整地恢复文件。ReiserFS is a kind of very good ifle system and also one of the earlier log ifle system on Linux. The ifle system has advanced logging mechanism, high disk utilization, fast search pattern and high performance characteristics. It is widely used on the system that requirement rapid processing of large ifles and many small ifles. At present, the domestic and foreign research on ReiserFS ifle system delete data recovery is less and there is no corresponding recovery technique documentation. Based on the understanding the ifle system structure and research, this paper proposes a ReiserFS delete ifle recovery method, the method in cases ifle is not overwritten to be able to complete recovery.
