I suggest either taking a full dd|bzip2 style backup of the hardisk to removable media for the simplest reinstall. Compliment with borgbackup or dervish for space efficient backups to capture more recent changes. Reinstall is the reverse .. lay down
the dd image update from the backups with rsync. No need to get caught in messy install routines that will take a lot longer with an uncertain outcome. I have a few arm systems and seem to be doing it at least once a month as the sdcards reach their
end of life.

Just for the sake of preventing a future failure, besides personal

so that I would be able to quickly restore the same full working
Gentoo in a new hardware without having to work from stage3 up? The
portage tree is one of those items, for sure. But what else?
Make a backup copy of everything under /etc.
I used to try to backup individual /etc/... files that I would need,
but I always forgot something.

Yes, besides /var/lib/portage/world and /etc/ you may also want to back up >> your /boot and kernel config, assuming the hardware (MoBo & peripherals) is the
same (same drivers). I wouldn't bother backing up portage, a resync will
download it afresh. You might want to save /distfiles if you're on a slow >> Internet link, but it has to be a copy of the current versions, otherwise the
latest version of each package source will have to be downloaded anyway.
If you're running databases you'll also want to keep a backup of the
respective /var/lib/*sql directory and if you're running a webserver /var/www/
* - but you would be aware of the need to keep a fresh backup of all this data
anyway.
Also good point, one can always do a "make oldconfig" on a new kernel
to recover specific tweaks.
Regarding backing up the portage tree, the binary packages won't do
much if the last sync is, say, one or two months old or even worse if
older. To use "emerge -K" one must have the same package version built
in the binary package as the one present in portage. That's what I'm
facing right now, it seems my binary packages won't be so helpful
after all - I'm beginning to think I'll have to go back to stage-3...
Thanks!
