看来有了【角色茶馆】后，大家讨论都热闹起来，将来大家可能都去过哪一桌也忘，只记得【角色茶馆】了。

I am busy with the methods to back up CentOS effectively. Do you have a better to do so, please let us know.

Do you like a simple bash script to tar every directory?

bubblestar

我也正在使用 ckleea 兄這個 script，現在我設定每星期自動做一次backup，但未試過restore，希望永遠不需要做這個restore 動作吧!

ckleea

這是非常簡單的 scripts? 重點是不用擔心 MBR overwrite during partition image restore. 架server係 backup 時仲行緊。

Restore 完全冇問題，所以可以放心。

哈哈！有了茶馆的帖子，那么有好的东西都放在这里，那么大家就有一个落脚点。

谢谢ckleea兄的信息，我有下列问题：

1）你的Restore Script是什么？

2）为什么分开那么多得档案呢？是否有特别含义？

角色

ckleea

This is a file/directory backup.

How to restore is
tar zxvf /path/zxvf/dev.tgz

Remember in linux, we do not have registry. All settings are in file based. Only when online, some of the files in /dev and /proc are temporary files created during execution. They can usually be able to back up.

So realtime backup is possible

Many Thanks.

The next question is how to quickly restore your system
1. ghost or true image backup / restore is easy to perform and usually very fast. One of the drawbacks I encountered before is the partition after restore may not be bootable in a multi boot environment. Very often when a partition is deleted and re-created, the order in partition table may be changed. In my case, I always write the linux grub boot loader in /dev/sda? or /dev/hda? instead of the MDR i.e. /dev/sda or dev/hda. Hence, this changes in order may result in not bootable restore

2. If I use script, I can control the location of restore and then issue command like this
grub-install --recheck
grub-install /dev/sda1

the first command shows me the bootable partition.
