Wow. One of my many WP sites was getting brute force attacked which caused my host suspend my account. This was all occurring while I was adding content. My connection to the DB kept getting interrupted and the site was running extremely slow. After adjusting my .htaccess to allow only my IP, I was able to research the problem and identify it.
My problem was solved after installing this plugin. It offers one-click solutions and has a built-in back up for files and DBs.
I highly recommend this plugin!
