1. Install preparation

   1. You need to prepare multiple partition for backup and restore.
      We assume that system has below partition table and has appropriate filesystem.
      /dev/hda1 /boot 100M Linux
      /dev/hda2 / 10G Linux
      /dev/hda3 Linux
      /dev/hda4 extended Linux
      /dev/hda5 10G Linux
      /dev/hda6 100M Linux
      /dev/hda7 10G Linux
      /dev/hda8 100M Linux
      /dev/hda9 30M Linux
      /dev/hda10 512M swap
      
      On this case we use /dev/hda9 as grub directory, and changed fstab as below;
      /dev/hda9 /grub ext3 defaults 1 3
      
      Then reboot the system.

   2. Install GRUB config.
      # mkdir /grub/grub
      # emacs /grub/grub/menu.lst

      
      default=0
      timeout=10
      title Fedora Core (2.4.22-1.2115.nptl)-1
      root (hd0,0)
      /boot/vmlinuz-2.4.22-1.2115.nptl ro root=LABEL=/ hdb=ide-scsi rhgb
      /boot/initrd-2.4.22-1.2115.nptl.img
      
      title Fedora Core (2.4.22-1.2115.nptl)-2
      root (hd0,5)
      kernel /boot/vmlinuz-2.4.22-1.2115.nptl ro root=LABEL=/ hdb=ide-scsi rhgb
      initrd /boot/initrd-2.4.22-1.2115.nptl.img
      
      title Fedora Core (2.4.22-1.2115.nptl)-3
      root (hd0,7)
      kernel /boot/vmlinuz-2.4.22-1.2115.nptl ro root=LABEL=/ hdb=ide-scsi rhgb
      initrd /boot/initrd-2.4.22-1.2115.nptl.img
      
      Edit boot.lst as below;
      # emacs /grub/grub/boot.lst
      1=1
      2=-2
      3=-3
      
      Edit bakup.lst as below;
      # emacs /grub/grub/boot.lst
      root=(hd0,0)
      partition=/dev/hda1
      partition=/dev/hda2
      swap=/dev/hda10
      
      root=(hd0,5)
      partition=/dev/hda6
      partition=/dev/hda5
      swap=/dev/hda10
      
      root=(hd0,7)
      partition=/dev/hda8
      partition=/dev/hda7
      swap=/dev/hda10
      

3. Install GRUB
   # tar xvfz grub-0.94.tar.gz
   # tar xvfz resumo.tgz
   # patch -p0 -d . -E <grub0.94-recovery.patch
   # cd grub-0.94
   # ./configure
   # make
   # cp ./stage1/stage1 ./stage2/stage2 ./grub/grub /grub/grub/

4. Setup GRUB
   # cd /grub/grub
   # ./grub
   grub> root (hd0,8)
   ......
   grub> setup (hd0)
   ......
   grub> quit

5. Install commands
   #cd resumo/bin/
   # make
   # cp ./cntinit ./backup /grub/bin
   
   Add counter file script to rc.sysinit.
   # emacs /etc/rc.sysinit
   
   You need to below line after line 572.
   # Make recovery counter file.
   /grub/bin/cntinit -c /grub/grub/counter /grub/grub/stage2

6. Backup filesystem.
   Backup to yesterday backup area.
   # /grub/bin/backup 2 /grub/grub
   
   Backup to old file backup area.
   # /grub/bin/backup 3 /grub/grub
   
   Then reboot the system and checks system boot normaly.
   # reboot

7. Make design faults.
   Intentionally poweroff during kernel boot, and check that system automatically boot from backuped area.
   
   # reboot
   During kernel loading, load the kernel module which makes panic and reboot (or push the reset button), GRUB automatically selects yesterday backup area.
   Warning! Sudden power off/reset may causes HDD crash! DO IT YOUR OWN RISK!
