Real-time backup software

[DMonster]

Ok, I searched from Google for quite a while but still cannot find the right solution for me.

I have a WD My Book Studio which acts as a primary storage for my photos. I wanna make a "real-time" or "raid-1-like" backup of my photo folder to another Buffalo USB disk drive connecting to the same Mac. So my requirement to the software is that whenever I copy new photos from my SD card to the photo folder in My Book Studio, the software would help me in the background to automatically create another copy to a specific folder in the Buffalo USB disk drive (just like RAID1). It looks simple but I can't find it....

Any buddy can help? Thanks!

I wonder if you might be able to do something like that with Automator...?

Thanks. I am a beginner of Mac actually. I did heard about Automator and used it to copy album art from songs in iTunes to the id3 tag, but that script is downloaded from the web.

Do you have any recommended script that can help me on that?
