摘要
文件系统备份和恢复过程中,需根据当前备份资源树和历史备份资源树进行合并等操作,这种操作在物理上表现为对目录树和资源树的处理。特别是增量备份时,它指明备份资源。恢复过程中,用户可以利用该策略根据时间点进行完全恢复和部分恢复。给出一种对备份资源树的解析算法,并进行分析,在算法的基础上对备份资源树进行了形式化描述。
During backup and restore of file system, it needs to merge current backup resource tree and previous one, namely operations between catalog tree and resource tree. It designates backup resource while incremental backup. Users can use these strategies to backup fully or partially according to time point. A parsing algorithm of backup resource tree is given and it is analyized, based on the algorithm the formal description ofbackun resource tree is given
