What a fantastic extension, having spent about 3 weeks preparing a new site for launch, i was taking regular backups using this extension, thinking it's prudent to have a copy, any way in my wisdom I decided to enable load balancing on my shared host account, and got the admin white screen of death ! nothing i did would solve the issue, so a reinstall of joomla was required. Clean install, fired up kickstart, went and put the kettle on, by the time the coffee was made the site was back, perfect in everyway !!! I would recommend that this is the first extension you install, I am a first time user of joomla, I have some coding skills and find the whole joomla environment inc, forums etc wonderful.
