There is an option to make an automatic backup whenever a project is uploaded to the web via the inbuilt FTP. In future updates and new versions can this be turned on by default.

It is inexcusable that no backups are made unless the user clicks the down arrow next to save and toggles this option on for every individual project. It is all very well that Incomedia remind users to create the more reliable iwzip manually once a week or so, but to have a built in backup option (albeit less than perfect) turned off by default seems ludicrous.
