要将linux完完全全的备份到另一颗抽取式硬盘，如果linux挂了，可以立刻升上来备援!!
由于对于linux 是ext3的格式，andy想到了几种方式..
1. 使用tar
2. 使用cp
3. 使用dd
4. 使用cpio
5. 使用ghost
试了半天，发现利用ghost的方式是最方便的，但之前听前辈说，ghost似乎没有支持ext3的格式，再苦寻半天及重复测试之后发现, 使用ghost 7.5以上版本即可。
方式如下:
1. 使用ghost Disk to Disk将原本的/dev/hda ghost到 /dev/hdb
2. 将原来的/dev/hda取下(不是bios disable就好哦..)，并将hdb设成master(也就是hda)
3. 使用Linux install开机片开机，选择rescue
4. 如果是ext2格式..以下面方式..
EXT2
When the file system is EXT2, use the following steps to recover the
partition. These steps have resolved this problem in at least one instance:
1. Start the computer from the linux installation CD.
2. Type:
linux recover
3. Respond to the prompts for language and location.
4. Type:
lilo -r /mnt/sysimage -C /etc/lilo.conf -v
exit
5. Remove the CD and restart the computer.
The computer starts into the linux partition.
如果是ext3依下面方式..
Symantec Ghost 7.5, EXT3
When the file system is EXT3, use the following steps to recover the partition.
NOTE: Only Symantec Ghost 7.5 supports the EXT3 file system. If you use a
Ghost version other than Symantec Ghost 7.5 with EXT3, the following information
is provided as a convenience only, and Symantec does not provide technical support
for using Ghost in this manner.
1. Start the computer from the linux installation CD.
2. Use the option linux Rescue.
3. Type the following at the Rescue Command Prompt:
e2fsck /dev/hda1
In this command line, hda represents the first IDE hard drive in the computer
and the "1" represents the first partition to repair.
4. If you see the message "Superblock has a bad ext3 journal (inode8).
Clear <y>?" press Y. You will see the message: "* * * ext3 journal has
been deleted - file system is now ext2 only * * * . "
5. Type:
tune2fs -j /dev/hda1
You will see the message "Creating journal inode: done . This file
system will be checked every . . . days".
6. Repeat steps 3 for each EXT3 partition on the computer.
7. Type: exit
8. Remove the CD and restart the computer.
The computer starts into the linux partition.
5. 一切ok后, mount /dev/hda 到/mnt
6. chroot /mnt
7. 重建lilo
/etc/lilo -v -v -v
如果是使用grub的请执行/sbi/grub-install即可。
一切ok。
