Hey guys I found a program that will back up just contacts and much more! its free, I've tested it (with contacts only) it works great! I attempted to post it in the apps section but I don't have permission, so maybe you can post it up.
It's called PIM back up 2.8

It's an exe, I put it on my storage card, then run it from file explorer or resco whichever you use, then the utility launches.
There are also other cool programs on this site.
