Made a mistake on my WP-site and had two options. Either rebuild the site partly or use the export file I made earlier with the light version of WPBackitup. Went for option 2. Purchased the pro version. Just selected the export file, clicked on restore and after a while my site was up and running again.
What I also like are the prompt responses from the creator of this plug-in. Questions were answered in hours. So, great support!
