VS2010 code repository options

I am a sole developer currently backing up my source code to .zip files on an external drive. Is it worthwhile for me to start looking at code repositories? What's the simplest, cheapest option for me? (ie. There is no need for lots of fancy features as the repository is just as开发者_开发知识库 a backup and not for sharing with a team).

... Forgot to mention. I use Visual Studio 2010 only.

Get yourself subversion, mercurial, git, cvs, anything is a vast improvement over zip files. You can generally get free plugins for VS as well although they aren't necessary.

Anything would be better then zip files.

For personal projects I would start with Git or SVN. Both are free and have addons for VS.

I've used Mercurial which has a plugin for VS2010 that can be found here:

But, as GIT does also, you can use it via command line.

SVN would be perfect for you!!

I use Visual Studio 2010 as well, and there's a great open source plugin for working with SVN - AnkhSVN

Since you're working with VS2010 I suggest you start working with TFS2010 Basic.
