Hi roko1, this one is limited to Windows Server as wp-cron is working as is scheduled exporting using the WP CRON engine. I have helped store owners in the past get WP CRON working under some IIS and Apache environments by setting up a manual CRON job to fire the WP CRON engine or toggling the alternate CRON engine built into WordPress. Try the following resources but as above our integration of WP CRON does work (I know as I recently left it exporting every 2 minutes overnight and got a shock the next morning in my Inbox).
