Unlike other simpler, non critical extensions, this one requires that you read all the documentation. A very small price to pay, given the alternatives of a hacked and destroyed site without backup!.
Although JoomlaCloner may at first seem complicated to the noobie, (er like me at WAMP)who tried to stubbornly implement without asking a couple of basic questions....I have to say, the support offered was exceptional.
I recieved immediate response and had my fully functional backup and localhost server implementation running like a dream.
I can now develop and test new features on my localhost 'test' sites and publish to my live production sites as needed. But better yet, I have peace of mind that no matter what may happen to my live sites, I have a backup plan and tools to fully restore my live sites quickly and easily.
Clone or die. Your choice.
