按着有的说法是,你得把/data1 umount ----ufsdump\r\nothter:\r\nuser fssnap backup\r\n但是我这这边总是在不umount filesystem 使用ufsdump online backup 从没有报LZ的错误

yuhuohu

建议umount在ufsdump很大一部分是为了怕在dump是有写操作发生导致文件系统不同步等\r\n\r\nyoyosys没umount做ufsdump估计是该文件系统在你ufsdump那部分数据时没有写操作的因素吧

我经常在系统正常跑的情况下.直接使用ufsdump 备份/及/var,这么多次了,也重没有抱过错,因为也没有ufsrestore操作过,所以不知道,当做恢复操作时会不会有影响.

我也是在系统正常跑的情况下.直接使用ufsdump 备份的。
