I have had two WordPress blogs hacked into in the past. That was at a time when I was doing very little internet marketing, and until I found time to address the situation (months later), these sites were penalised in the search engines. They were not removed, but the rankings were reduced.
WordPress cloning, as it applies to repair hacked wordpress site, is the act of creating an exact copy of your WordPress install. What's good is that in only a couple clicks, you can do it with the right software. There are a lot of reasons why you may want to do this. Here are only a few.
Also, don't make the mistake of thinking that your hosting company will have your back so far as WordPress copies go. Not always. It has been my experience that the company may or might not be doing backups while they say that they do. Take that kind of chance?
Keep your WordPress Installation up to date - One of the easiest and most valuable tasks you can do yourself is to make sure your WordPress installation is updated. WordPress provides a notice in your dashboard to you, so there's really no reason.
As I (our investigate this site untrue Joe the Hacker) understand, people have way too many usernames and passwords to remember. You have got Twitter, Facebook, your online banking, LinkedIn, two blog logins, FTP, internet hosting, etc. accounts that all come with logins and passwords you need to remember.
Utilizing a plugin for WordPress security just makes great sense. Backups need to be performed on a regular basis. Don't become a victim of not being proactive about your 16, because!
