I mentioned in a comment somewhere that it would be smart of your web host, such as Dreamhost, to include url shortener/tracker app to their list of “one-click install” apps. They could build their own or consider the software from http://yourls.org. You pick which domain to run the app on and that’s it, you have a self-hosted url shortener with built-in backups and statistics. They could even integrate an Amazon s3 or other data backup features.
