I've always used a pair of removable caddies and have it set up
so I can reboot, put in a fresh unformatted drive, and go all the

the backup, and then reboot directly onto the backup drive...
without any intermediate reboots. Using an external firewire
drive I would imagine would also work with even less rebooting.
I put this file in /etc which gets rsync'd to the backup drive
and I use the following bash function (in .bashrc) to fire it off...
# cat /etc/lilo.hdc (which ends up in /mnt/hdc5/etc/lilo.hdc)
boot = /dev/hdc
disk = /dev/hdc
bios = 0x80
delay = 1
install=menu
image = /boot/vmlinuz
root = /dev/hda5
label = linux

local BU_MNT=/mnt/hdc5
mount --bind /dev $BU_MNT/dev # for devfs
mount --bind /proc $BU_MNT/proc
chroot $BU_MNT /sbin/lilo -L -C /etc/lilo.hdc
umount $BU_MNT/dev
umount $BU_MNT/proc

This is not exactly audio related but it has to do with using
HDDs for backing up the system as well as the data.
--markc
rsync -av --delete --exclude
'/mnt/backup/' / /mnt/backup/
So /mnt/backup/ is then an exact copy of /, and the best part is, it's
bootable and functions just like the original drive(s) if I stick it
on the motherboard. And the backup process usually takes just about a
half an hour, depending on how much new data I've added, of course.
Are you sure it's really bootable? Maybe you should try it.
I doubt that the MBR, /etc/fstab and /etc/lilo.conf are correct for a
single-disk configuration. These should be easy to fix as part of the
recovery process, but you're going to need to boot a rescue disk first
and reconfigure for the new hard disk.
