solaris10 backup

qrange · 10-24-2018, 06:43 AM

I'd like to backup few Solaris 10 servers with tar (everything, including OS).
is it possible to backup all the filesystem (ufs) metadata so that it can be restored and boot?
I would use dd or similar to backup slices info, etc. But also need a way to preserve everything else that tar skips.
Its a sparc version.

Thanks.

Not sure about "bootable" (it's been a little bit since I've tried it), but flar is what you're after:

Why not to use "ufsdump" instead of tar?
But either way, to restore/install bootblock you would need something like this (booted from Solaris install CD/DVD):

Code:

# cd /tmp/slice0/usr/platform/'uname -m'/lib/fs/ufs
# installboot bootblk /dev/rdsk/c0t0d0s0

To backup metadate:

Code:

prtvtoc /dev/rdsk/c1t0d0s2 > /mnt/solaris/`date +%Y-%m-%d`_`uname -n`_c1t0d0.vtoc
