Backup instructions for the database of your Wordpress Blogs can be found in the Wordpress Codex. These instructions are really comprehensive. So, something good has come out of my problem with my blog. There is still more to learn because I do want to know why it happened.

Although I have deleted it and uploaded the site from my hard drive I am still getting the Wordpress Install page . However, I am getting closer to the source of the problem. When I find out I will report it. Meanwhile, be sure to read the step-by-step instructions for backing up your database. I am going to study it.
