Minux the /home directory, what does the community feels is the most peritnent information that must be backed up on linux box. Assuming that DNS, Apache, DHCP, Samba, SMTP, POP, firewall, etc... meaning if the system was a full service machine or even across multiple machine, what do you backup?
On any of my production machines, I have the following tagged for nightly backup:
All servers back up: /root, /etc, /var/spool/cron, /usr/local/share/snmp
YP/User server adds: /var/yp, /usr/local/apache, /home
Dedicated Webservers add: /var/www, /usr/lib/apache, /usr/lib/php4
MySQL server adds: YP clients add: /var/lib/mysql /usr/lib/yp
Mail spool adds: List servers add: /var/mail /home/mailman
Central (apache) logging & webalizer server adds: /var/www
Take your pick.
What backup tools (freeware) do you use often or recommend in SOHO environment? I've used netcat and dd ing info to another box, but haven't really done too much to write to other medias since most of my boxes are network related boxes...
Considering how cheap hard drives are, I use RSYNC to dump all the data to central servers every night onto 80/120 Gb drives. I maintain one month of nightly backups (120 Gb), 52 Sundays (80 Gb), and 12 last day of the month (80 Gb) across three separate drives. Those drives are also mirrored (not RAID), just in case. And to be even more anal, I also keep the same monthly backups on a 66Gb tape... Call it overkill if you will, but my users feel safe.
And before you ask, I don't create physical files every night. I make use of hard links in my backups, keeps things nice and tight.
