Normally, you can do something like this in /etc/fstab

/dev/hda1     /           ext3       defaults,errors=remount-ro    0       1
/dev/hda2    /home    ext3       defaults,errors=remount-ro    0       0
/dev/hda3    /usr       ext3       defaults,errors=remount-ro     0      0

Or something very similar. Sorry, I don't have a live example to paste
here because at the moment my / (and everything under) is the whole
drive and /mount/backup is a second hard drive. Someone might be able
to give you a better example.
