如何知道服务器做了镜像，如何卸除镜像

hechen

我感觉镜像没有什么用途，所以想用DD来硬备一个盘来代替它。
有高人就给我指点指点。说说厉害关系。

镜像是实时的
DD是冷备份的

Mirrored disks are very useful for critical servers,
like production web servers, DB servers, and mail servers.
If it is configured correctly, you system will be up and running
when some of the disks are dead.

A back up (bootble) disk with the OS and all data, is good for
production servers, too. You always can boot from it so all your
services are ready and you have time to repair other disks.
Of course, it is at lease one day old, and for DB servers, like Oracle, you can not do it unless you can stop the DB to do a cold back
up or use RMAN.
