There is no point in backup of files other than those you modify yourself, unless you plan to create an exact image and recover using dd. After installation you can do # date > /tmp/TIMESTAMP then you can create a list of files that have been modified after that time with find, # find / -newer /tmp/TIMESTAMP > /tmp/backupfilelist If you have a backup cronjob, then you can use the same method to backup only files modified since last backup. On a base system with no services running, I'd restrict backup to /etc /home If you've got any ports installed, add /usr/local/etc /var/db/ports What else to add to the list really depends on which services you run, named, mail, cvs, web, ftp, nis, etc. and if these have critical files in other directories. If you have any databases or ldap service, then you want to add those as well, but it is recommended to dump these rather than backup the files themselves. I wouldn't backup source or the ports distribution, you have an online backup available :) If you rely on a particular snapshot, then you should configure that in your supfiles. But if you need to recover without network access you should backup source and the ports tree as well as distfiles or build packages whenever you install from ports and keep those backed up.
