in Creed 2 WTF?

I played and beat AC2 a while back, and I recently was looking at my trophies and noticed I only needed 3 trophies to get the platinum. But I have bought a new ps3 and all my data was saved on my old PS3. So, I grabbed my trusty USB stick, plugged it into my old PS3 and, tried to copy the AC2 save file to the USB. But when I selected copy it only gave me the option to copy to Online Storage. When I try to copy any other game file I can copy it to my USB, so why not AC2? How can I just put the game file on my new PS3?
