Thank you for your review!
I agree that untested backups are scary. In fact, my mantra is that an untested backup is worth as having no backup. That's why I ask people to test their backups, at least every time they make a major change on their sites.
Testing your backups is very easy. You can use XAMPP, MAMP, WAMPServer, Zend Server CE or any other pre-packaged local server environment to create a fully functional web server running off your local computer in seconds, without any specialised knowledge. You can then use Kickstart to extract the archive and restore it on this local testing server.
For more information you can take a look in our Quick Start Guide. If you ever get stuck during restoration, just go to our site's Documentation, Troubleshooting section where 99% of your questions are readily answered with detailed troubleshooting instructions.
