If the server is mission critical you can clone the hard disk with CentOS inside. Anything goes wrong you simpy swap the disk. The clone needs either exactly the same size of just larger.
If the source is sda (or hda) and the target is sdb (or hdb, the one to be written on) the cloning is just Code:
dd if=/dev/sda of=/dev/sdb bs=32256 To put it on an image you need to run an operating system to restore it. |

Are you saying that every time you have ANY problems with your server, the only thing you do is reinstall it?? And what do you mean by "some configuration"?? If you searched on LQ, or on Google, you'd find lots of references to how to create recovery disks. DD is one option, but you can also use mkcdrec, mondoarchive, and systemimager. |
still it is not clear for me

I gave you the names of three packages, which do what you want. Look them up, read the documentation. Search the threads on this VERY SITE, which will tell you more. |
I echo TB0ne sentiment here.
Although I have offered my advice generically it would be better for the OP to do some work himself/herself in order to get the real benefit of any advice. |

Does the OP honestly expect people here to type out the exact sets of directions/notes/etc., for three different software packages, and tailor those notes to their installation?? No, sorry....pointed the OP in the right direction, gave options...time for the OP to do some reading. Far different if the post is "I'm getting error XXXXX using Distro yy.zz, anyone have ideas?" |
