[SunHELP] Backup the whole system disk

[Hitoshi TAKAHASHI]

Hi Will-san & Peter-san,
I appreciate your advice.

The device, /dev/md/dsk/d0, is only striped (RAID 5 structure) and
stored normal data.
As Peter-san said last, the os treat it as UFS.

I'll try to do ufsdump for it on single user mode.

Thanks,

-Hitoshi-
