Just use dump(8) to back up the filesystem with the user home directories and also back up where-ever you have the /etc/... file tree. It is all in /etc/passwd, /etc/group and /etc/master.passwd, plus wherever you put home directories. jerry > > Thank you in advance. > > Regards > Rambius > > -- > Tangra Mega Rock: http://www.radiotangra.com > ___ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Re: How to backup the users
You might as well save the whole /etc, you will probably need other conf files and surely you would like to have /etc/passwd and /etc/group not passwd - is generated from master.passwd but group - yes, sorry i missed it. In fact, I would also backup the whole /usr/local/etc to get all the configuration settings for my services and so on. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]" ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Ivan "Rambius" Ivanov wrote: I was only unsure how to proceed with the users backup. If users are the only thing you wish to back up: /home /etc/group /etc/master.passwd You can backup system files (/etc, /usr/local/etc, /var) if you want but that's another topic. Some hints: 1. Check if there are users who have their home-dir outside /home... 2. Check /tmp to see if users have files there (they shouldn't count on those being preserved, that's not what /tmp is for, but you might want to offer a little bit of extra service by doing this anyway) 3. There might be slight differences between the current /etc/group and /etc/master.passwd and the ones on the new system. So, instead of blindly copying the old ones onto the new system, I suggest you add the relevant entries in the old files to the new files by hand (or script). 4. If you copy the encrypted passwords, then users don't need to set a new password after you've reinstalled the system. 5. Keep track of UIDs/GIDs: you might need to do some chowning to give everybody their files back if their (numerical) UIDs/GIDs have changed. 6. If you don't need to repartition your disks, it might be an option to just leave /home alone during the reinstall (set the newfs flag to N). That leaves /home untouched and you can just mount it afterwards.

In fact, it hosts only a cvs repository and a web server and I have already backed them up. I was only unsure how to proceed with the users backup.

A good, general rule of thumb for backing up a system is: /etc /usr/local/etc /home /var /var is the wildcard here ... /etc and /usr/local/etc are generally very small. /home can be huge, but if it is, it's probably because there is a lot of important data there. But /var can be large with a lot of stuff that you may not want to back up. Do you need /var/log, for example? Frankly, if you have enough space to back up, I recommend you back up the entire system and restore selectively. Do you have, for example, a database in /usr/local/pgsql? If you're asking this question, you're probably better off safe than sorry. -- Bill Moran http://www.potentialtech.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
