Theoretically, a "bare-metal" restore should be possible by backing up the
entire filesystem. The restore procedure to a new piece of bare-metal would
be:

  1. Boot from rescue media
  2. Partition the new disk and mkfs it
  3. Restore the server image to the new disk (either by networked rsync
or untar'ing a tarball downloaded from the backuppc restore interface)
  4. chroot into the restored disk and install grub (bootloader)
  5. exit chroot, unmount new disk and reboot the system


In practice though, I've found it takes lots of tries to perfect the above
procedure and it's often easier to re-install the base OS and just restore
critical config files, application files and data to the box. Bare-metal
restores *sound* sexy, but really they're often just not useful.
