System Backup
Hi All,

Is it possible for us to do the Solaris system backup online without shutdown the system to another disk and if any disaster of hardware failure then we can boot the system up from the that backup disk?

Thanks.

- Create a 3 way mirror.
- Make the mirrored disk bootable(use installboot)
- nvalias the disks (ie: root, rootmirror1, rootmirror2)
- metadetach the 3rd disk(rootmirror2).

You still have your mirrored boot disk and now you have a third disk with a point in time image of your boot disk that you can boot from via boot rootmirror2 from the OBP.

If you only have 2 disks, then you have a mired boot disk or a single boot disk with a second offline copy that you can boot from.

Hi Tornado,

If I just have one disk and I do not want to use the mirror is it got any other ways that I can do the whole system backup like using "ufsdump"?

Thanks.
