nbu oracle rac 备份 问题

如果归档时在共享存储上。那么只要备份一边就可以了，你可以看一下，2个节点的归档日志会有一些区别的，比如文件名有加-1或-2之类的，应该是比较好辨别的

如下是备份归档时的日志输出，archive log list查看“Archive destination            +RAC_DISK”都是+rac_disk，是不是“thread_1”和“thread_2”分别代表节点1和2的归档日志。

对，应该是代表节点一和节点而，这个应该和archive log的命名规则有关系

你的是ASM,是共享的。看日志应该是2个节点都有备份。如果是文件系统，可以NFS2边都识别到归档日志（不推荐），要不分配通道是制定2个节点即可。
