How to make smaller backup images of Rpi SD card?

I always keep backups of my raspberry pi's, but the only way that I've ever seen to do this is using the dd command on OSX. It works fine, I keep a few backups this way, and it's very easy, but it becomes troublesome when every backup is the full size of the SD card, which is usually 16GB. I'm pretty sure I've seen people upload their rPi images to websites before with much smaller file sizes. Is there a better way to do this? Any way to backup a pi without a huge file size, or maybe compress it afterward?
