Last year and a half taught us that WordPress security should not be taken lightly by any means. Between 15% and 20% of the world's high traffic sites are powered by WordPress. The fact that it is an Open Source platform and everybody has access to its Source Code makes it a tempting prey for hackers.
Cloning your website is another degree in secure your wordpress website which can be very useful. Cloning simply means that you've backed up your website to a totally different location, (offline, as in a folder, so as to not have SEO problems) where you can access it at a moment's notice if necessary.
Should your site's server go down, everything you have worked for will go with this. You will make no sales, get signups or no visitors to your site, until you get the website back up 32, and in short, you are out of business.
Fortunately, keeping your WordPress website up-to-date is one of the easiest things you can do. For the past couple of versions, the ability to install automatic updates has been included by WordPress. Not only that, but websites are notified every time a new update becomes available.
You may extend the plugin features with premium plugins such as: Amazon S3 plugin, Members only plugin, DropShop etc.. So I think you can use it and this plugin is a good choice.
Just make sure you decide on a plugin that see here now is current with release and the version of WordPress, and which you may schedule, restore and clone.
