I've had two WordPress blogs hacked into formerly. That was at a time when I was doing almost no online marketing, and until I found time to handle the situation (weeks later), these sites were penalized at the major search engines. They were not eliminated the evaluations were reduced.
If parts of your database were to disappear, how viable would your website or business be ? Let us look at what you need to do to execute fix hacked wordpress database cloning, and how it can help your general that is WordPress security .
The more powerful approach, and the one I recommend, is to use one of the password creation and storage plugins available on your browser. I believe after a trial period, you need to pay for it, although RoboForm is liked by people. I use the free version of Lastpass, and I recommend it for those of you who description use Firefox or Internet Explorer. That will generate passwords for you.
Yes, you need to do regular backups of your site. I recommend at least a weekly database backup and a monthly "full" backup. More, if at all possible. Definitely more if you make changes and frequent additions to your site. If you make changes multiple times every day, or have a community of people that are in there all the time, a daily backup should be a minimum.
Along with adding a secret key to your wp-config.php file, also think about changing your user password to something that's strong and unique. A good idea is to avoid phrases, use upper and lowercase letters, and include numbers, although you will be told the strength of your password by wordPress. It's also a good idea to change your password regularly - say once.
There is another problem you have with WordPress. People always know where they websites can login and additionally they could just visit your login form and try a different combination of user accounts and passwords out. In order to stop this from happening you want to set up try this Login Lockdown. It is a plugin that allows users to attempt to login with a wrong password three times. After that the IP address will be banned from the server for a certain timeframe.
