Disaster Recovery for Red Hat Server

Need to work out a procedure for backup and recovery the Red Hat servers for disaster recovery. Any free RedHat solution that can allow me to fully restore the machine into original state.

Do I need to keep the exact RedHat core as the orginal machine ? Should I need to partition the disks as the faulty server ? Which folder should be exclusive for recovery (say, OS kernel, ...)

Tks

If you want simple backup you could use tar or cpio to backup directories locally and offload them to another server or storage for safe keeping, or to tape if available/applicable.

As for free backup solutions, there are a few out there, one of the better known ones is bacula

As what to backup, that indeed depends like arnold said, what is installed, are there scripts that need to be in backup, files in /var/www maybe, /var/lib, /var/spool ...

"System function,  Commonly /etc is the per system configuration.  Other items vp can be stored in different location" - I can't get your message. Can you explain more...

The server is php server with some php programs running on it .. guessing it is a standard redhat configuration. Anything need to be check...

Tks again.
I think arnold is referring to what I told above:

As what to backup, that indeed depends like arnold said, what is installed, are there scripts that need to be in backup, files in /var/www maybe, /var/lib, /var/spool ...

Meaning that you will need to find out where all the important files are located, if it's php-files from a website they can be located in /var/www/<some-folder>, but you might also like to backup files under /etc/apache2/sites-enabled for instance ... But that is for you to figure out, we don't know what is important to you.
