[SunHELP] Backup the whole system disk

[Peter Stokes]

Hi

Firstly use the mount or df command to establish which partitions you have
mounted. Each one will be of the form /dev/dsk/cXtYdZsA. ignore /tmp.

Then use ufsdump to dump each partition to tape eg ufsdump 0f /dev/rmt/0n
/dev/dsk/cXtYdZsA for the first tape drive

If using one tape remember to use the non rewind device entry /dev/rmt/0n
and not the rewind device /dev/rmt/0 to store successive partitions.

When you have put each partition to tape, it is a simple matter of using
ufsrestore to restore the partition. The great thing about ufsdump is that
it preserves all of the data including device nodes and saves only physical
disk partitions not the whole logical tree. Great for moving/changing disks
etc.

I find it useful to also save away at the same time a copy of df -k to show
what the parttion sizes are.

Peter

Hi all,

Please tell me how to preserve backup data of the whole system disk
on DDS4 tape.
Our system is Solaris 2.6 running on EP250(sparc).

Regards,
