You can use RAID mechanism.

Hi
You can:
1) dd to clone whole hard disk;
2) rsync to create filesystem snapshot on the backup hard drive. Also installation of the grub is needed on the backup hdd.

rsync is available (Centos5) from the rpmforge.

You are aware that Centos only supports the most current minor release of each version? Of the Centos5.X line only 5.5 is (currently) supported. Moving from Centos5.3 to 5.5 is only a yum update away.
