Can Hazel do the job? Immediate copy to external HD + sync!

Hi guys,
I'm an photographer, and i'm getting more and more important clients! So, the things i shoot, I can and may not loose!
So, I bought this external hard drive, and my plan was:
When I'm on assignment, I shoot tethered thrue the computer. The files are then stored in "x" subfolders.
What I want, is that every time a new image is getting added to that folder, on my mac hard drive, it's instantly copied to the external hard drive - some kind of raid 1 behaviour!
And, I also need it to sync, so when I delete a file on my mac, it actually also deletes it on the external drive!
Is that by any chance possible?
Thanks in advance
