Finally, you can not worry about experimenting with your site design or adding some new content. We’ve added Site History feature to our editor, so now you can save and store different versions of your site. These versions can be restored to bring a site back to the point in time when the particular version was made. 

Keep in mind that you can store up to 5 versions of your free site and up to 100 versions of the Pro site.

Check our complete guide for backing up a site version.
