You should backup all in / except
/tmp/*
/sys/*
/proc/*
/lost+found/*
/dev/*
Distfiles are saved outside the root and I can afford to rebuild world. My
main concern was losing (gentoo) config files, speaking of which, I
remembered to back up /usr/src/linux/.config, and user folders.
I have no solution how to bzip or gzip your backups or how to make a dvd
backup, but I use "app-backup/rsnapshot" which uses rsync but implements
an intelligent rotating system that is done daily, weekly, monthly,
yearly according to your config. Of course you should store the backup
on another physical hdd.
