Save Projects to Online Storage?

Hey y'all.
I was just wondering that whenever you click save on your project files in your IDE,
It would get saved to PC and Online Storage(free one) and the next time you click save it would save the changes made.
I just feel it is annoying having to plug in a USB and save it on to that. Because I have 1 computer and 1 laptop. It is a hassle having to keep putting a USB in your computer then in to your laptop.
And I sometimes go abroad so I forget to update the files in my laptop and then realize that they are still on my PC. So I thought does anyone know an Online Storage that would do.

IDE:Netbeans 6.9
Netbook
PC

Thanks

Hi,

Welcome to JavaRanch!

What you're looking for is a "version control system". There are plenty, including ones that you can use online for free. First you need to google to learn about CVS, Subversion, Git, and other such systems; then you can look at online providers, like SourceForge. Of course, you can have your own server, as well, if you want to keep your data private.

Use google Code , to upload your files .

I did not understand the CVS, please could you give a steps instruction.
Anyways I found another way using DropBox.
But I just need to know how to save my projects when I click save in netbeans to 2 separate locations

Thanks
