I am currently using rsnapshot to back up these directories on a

Here is my exclude list from my rsnapshot.conf
exclude /var/log
exclude /var/tmp
exclude /usr/obj
exclude /usr/ports/distfiles
exclude /usr/local/squid
Also I backup by file system, so I'm already excluding /tmp
Yes, it's easy to miss something that should have been backed up. 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.
