[SunHELP] Backup the whole system disk

[Peter Stokes]

Hi Hitoshi

Never used it with disksuite, but in principle it should work assuming that
the partition appears to the os as a ufs partition.

Hi Peter-san,

Thank you for your advice !!
I'll try to preserve backup patitions (see below) on your advice.

# df -k
Filesystem            kbytes    used   avail capacity  Mounted on
/dev/dsk/c0t0d0s0    10697176  317638 10272567     3%    /
/dev/dsk/c0t0d0s6    2056211 1659502  335023    84%    /usr
/proc                      0       0       0     0%    /proc
fd                         0       0       0     0%    /dev/fd
/dev/dsk/c0t0d0s7    3099287  271374 2765928     9%    /export/home
swap                 1932552      80 1932472     1%    /tmp
/dev/dsk/c1t3d0s7    35153689 2508543 32293610     8%    /export/med/hd
/dev/md/dsk/d0       295399001 2526500 289918511     1%
/export/med/hd/0000

If you know about following, please give me an additinal advice.
Can I preserve the backup data of /dev/md/dsk/d0 using ufsdump ?
/dev/md/dsk/d0 is SOFT RAID established by Solstice Disksuite 4.1.

Regard,
