Let's imagine the following situation: web site with modules was created and published. You created copy of this web site. Newly created web site will not have publishing settings set, because publishing to the same location does not make sence.
Site stores their data at published site, we have 2 options:
1. during site copying Sitebuilder should make copy data from published site via FTP/XCOPY/VPS
2. create dumb data (empty database)
We'd prefer to go with 2-nd option. What is your expectations?
