That backs up a lot of stuff that isn't needed. As long as you ha= ve /etc
and /var/lib you can recreate the system. Depending on space vs. time,
you may prefer not to backup the gigabytes in /usr that can be recreated by portage (although saving /usr/local is a good idea).


Thanks a lot f= or the valuable advice. I have a dozen of scripts in /usr/local/bin=A0

RAID is not an alternative to backups, a corrupted filesystem on a RA= ID is
just as corrupted as if it were on a single disk, you just get extra
copies of the corruption.

I did no= t know that. I was thinking of, in couple of months, buying a notebook=A0

Despite the cost of living, have you noticed how it remains so popular?
