What about "duplicating and updating" /, /var and /usr onto a 2nd disk ?
This could be automatically done by a shellscript. You only need to
fine tune /mirror/etc/fstab to boot from the correct disk after a
such a "backup/mirror" run ....
If you install the freebsd boot manager you can even easily test
booting from the 2nd drive without having to make special settings
in the forth boot loader.
You could manage this using three disks I think
Disk: da0 da1 da2
Fs:
================================================================+
root-fs | s1a s1a (backup) | |
------------------------------------------------+ |
swap | swap swap | |
------------------------------------------------+ swap |
var-fs | s1f s1f (backup) | |
------------------------------------------------+ |
usr-fs | s1g s1g (backup) | |
------------------------------------------------+---------------+
vinum RAID5 | /usr/local |
------------------------------------------------+---------------+
vinum RAID5 | /home |
------------------------------------------------+---------------+
I'm not sure, maybe its even possible to put /var onto a
Vinum Software RAID-5 ......
