You can boot about any Linux live or install CD that lets you get to the shell (with a Centos install disk, enter 'linux rescue' at the boot prompt) and use dd to copy the raw disk devices: dd if=/dev/sda of=/dev/sdb bs=1M Be sure you understand the device names for each disk. Using 'fdisk -l' to see the existing partition layout might help with that.
However, this is a slow process because the entire disk will be copied, whether it is used or not. If you are going to do it often, clonezilla is much faster because it knows enough about most linux and windows filesystems to only copy the used part of the disk and can store compressed image copies on a local or network disk. The clonezilla-live version is a bootable CD (or USB image). For larger scale cloning you can install the full version with DRBL for network booting into the clone process. http://clonezilla.org/clonezilla-live/
