All,
I currently have a system that is going to be moved onto some new
hardware. The system is currently running solaris 7 on a sparc station
10. It will then be moved onto an Ultra 10 workstation still running
solaris 7. My question is how do I backup the entire system so that I
can
restore it on the new ultra 10. My guess was to use cpio. However I am
fairly new to solaris. How would I do this? Also will the cpio arhive
then work on different architechture? My best guess is to back the whole
system up is to do. find . | cpio -H odc -ov /destination/path However
if that creates the backup archive how do you apply it to the new
system?
You can use either tar/cpio/pax to do mostly the same thing, or ufsdump to
do something similar. I usually use tar, for which the command to create
an archive would be:
cd /path/to/stuff/to/backup && tar -cf /path/to/backup.tar .
and to restore is
cd /path/to/restore/to && tar -xpf /path/to/backup.tar
Tar/cpio/pax archives can usually be moved across hw and os platforms,
though not all data may be restored in some cases (e.g. metadata or > 8.3
filenames on msdos fs).
Be careful what all you restore. You do not want to write over certain
files in /etc /dev /kernel and other places, even though you are going
from 7 to 7 on Sparc architecture. Writing over some of these files (like
/etc/path_to_inst) may result in a server that does not boot.
Best is to keep data and customizations separate from the base OS so you
know what else you have to install after such a change, and to track what
config files you have customized in the base system.
Good luck,
