Version your client assets. E.g. <img src="/img/v2.12.35/logo.gif" /> <link rel="stylesheet" type="text/css" href="/css/v2.12.35/frontpage.css" />
As someone mentioned before, hard-linking old and new deploy files means duplicated content doesn't cost any disk space. Rotate out old deploys past X days, and use strong cache controls to expire the content quickly.
