[opensuse] Re: backup of users on a server

Hi,
I would like to upgrade my server which runs OpenSuSE 10.3 to the latest version. I wanted to know is it possible to have a backup of all users, passwords and all home directories, so when I install new OS, just simply transfer all data of users to the new system?
Thanks,
D.
probably not with a so old distro. Not sure if the UID are still the same. Do they begin at 1000 like today or 500 like before? if 1000, you can save /etc/passwd, /etc/shadow and /home jdd -- http://www.dodin.net http://www.facebook.com/pages/I-support-the-Linux-Documentation-Project/3720... http://www.facebook.com/pages/The-fan-page-of-Claire-Dodin/106485119372062?v... -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
Thanks for the answer. Yes UID starts from 1000 in OpenSuSE 10.3. Well, it is not that old, but are you sure just by backing up /etc/passwd, /etc/shadow and /home everything will be as it was on the old server, even on the new server? How usernames will be transferred? What is "shadow" file? D. On 2010-06-21 16:46, jdd-gmane wrote:

of course like said an other answer, depends how the server is configured (by you). How usernames will be transferred? What
is "shadow" file?
the place where real passwd are stored (the /etc/passwd file just hold names and various options, shadow hold the pass). May be? you have also the use of the /etc/groups file, but this is not so sure jdd -- http://www.dodin.net http://www.facebook.com/pages/I-support-the-Linux-Documentation-Project/3720... http://www.facebook.com/pages/The-fan-page-of-Claire-Dodin/106485119372062?v... -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I would back those up. HOWEVER, I would only add back in the new /etc files the users I want to keep. I would not in any way overwrite the system users in these files. Also, I would be sure the group names have not changed. Like dialout vs. uucp. Just to be safe. -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Krukmakargatan 21 P.O.
