When I clicked restore.php, Chrome blocked my access with a big red screen stating that what I was trying to do contained malware from logiclord.com.
With this plugin being hosted in the WordPress repository I decided to go ahead and run it. This may have been a false positive because of the invasive nature of this type of restoration (overwriting the config file and all) but it made me feel uncomfortable having that happen.
It did end up doing a very mediocre job of restoring my site.
Although the basic elements of my site were restored (in other words, I could recognize the theme), it was by no means a complete restoration of my original site. Pretty much nothing was where it should have been. It was obvious that most of the theme and plugin configurations had been lost.
Mind you, I have done a lot of work on this site, and it has many custom configurations, so I would have been impressed if it had been perfect, but it was not even close.
This plugin may work with simple WordPress sites with few modifications, but I cannot recommend it from my experience with it.
Still, to try to create a plugin to perform an automated restoration is an impressive undertaking, and I thank the developer for the time and effort invested in developing this plugin.
I am going to try XCloner and see if it does a better job.
