Hi, sorry for the delay (I'm too busy with real life stuff). I'm quite sure xbox-scene admins have a proper modern backup. You should ask them about.
All I have from the web is this: http://www.4shared.com/file/257784570/9cc9007e/layouts.html
An April 2005 layout backup.It's about 540 layouts.
About the web itself...I don't have any backup for the php code, but except for the tutorials and binaries it's not something really hard to rebuild (in fact the web was just 3 free php scripts I got from somewhere, one for the news, another for the file manager and a final one for the forum).
It's all I have. Sorry.
