You should be able to click on the contacts icon, hit the menu button, and you should see in the bottom left corner an option to Import/Export. You can export your contacts to your to sd card. From there you can copy the exported file (something like .0001.vcf) to your computer if you wanna make sure your contacts are saved. Should anything happen to your contacts and you wanna restore with this file, just follow the first couple steps and instead of export, you import the previously saved file.
