I've got Umbraco 6 running nicely on my Azure space now but I have an issue with media.

Whenever I publish up a new copy of the site, the media files are overwritten on the server. Is there a way that I can set this up so that I can access the media files (so I can recreate a local copy of the system) but still update the content locally, or will I have to do all the content entry on my dev machine and push everything up via an Azure package? (which kind of defeats the purpose of a CMS...)
