摘　　要：数据库备份与恢复是地震前兆台网数据库维护的一项重要工作,目前普遍使用冷备份方法。给出数据泵逻辑备份的新方法,并结合地震前兆数据库特点,介绍数据泵备份在地震前兆数据库中的应用以及备份与恢复中常见问题的解决方案。Database backup and recovery is one of the most important parts of earthquake precursor network database maintenance. Now the common method is cold backup which preserves the information on hard disk. Under this situation, here a new backup method, logical data pump backup is provided. Combined with the characteristics of earthquake precursors database, it shows the application of data pump backup on earthquake precursor database and the method to solve problems which happen commonly.
