Thanks for the advice ??
The why is: I created a site for client using WP, client promised to install apache and sql, but he didn’t yet, but he wants to have the site online now. And of course with regular updates. So the site runs on my server for now and I do a download-all-and-copy-it-to-another-server process every few days. I thought there must be something simpler, I dont want to have mor work than clicking a button in WP or running a batch file :). Lazy programmer is a good programmer ??
