Simple way to back-up hard drive?


I'm a photographer with loads of digital photo files and important docments on my hard drive and I have a few firewire external hard drives as well. I just want to know if there is an easy way to back-up everything on my hard drive which is a file I created. Can I just drag and drop? I do not need to bacj-up system software or any applications, just all of my text files, photos and video work. I am running Panther. Any help greatly appreciated, I know there has to be a better way than going through every folder and dragging them one by one!
