I am working on methods for recovery of a Linux
server, and I wanted to run this by the group for
comments or recommendations, since I'm new to
this. I have a server which acts as an email
relay, storing no mail locally. It also stores
no other data, besides the configuration data for
its mail systems. I plan to set up an automated,
regular complete backup for it, but I was also
considering this: Say I have among my partitions
on this box:
sda2 /
sda3 /backups
sda5 /var/log
sda7 /var/spool
Let's say I set up mirrordir to keep /backups
(sda3) mirrored from / (sda2) maybe once per
night or week. Then, if I manage to mess up the
OS (as I recently did, running tripwire and
up2date at the same time - don't ask) and the
machine won't boot, I wouldn't have to resort to
a rebuild and the tape backup. I could boot the
box to my LNX-BBC CD (or a Tom's root boot),
change fstab to mount sda3 as / and sda2 as
/backups, and reboot the box. As long as
mirrordir hadn't yet copied whatever corruption
was in the OS, I should be able to boot and go
just as things were the last time mirrordir ran,
right????????? Better ways to do this?
