Just thought I would put an update to this and will now mark this as resolved (by myself).
Here's what I did to fix the Auto Database Backup, and the "Create Database Backup" button from displaying a white screen.
First Make a backup of everything!! to include your database.
Backup ALL FILES, Database, and EXPORT Your posts, pages, etc. via dashboard -> Tools -> Export select "All Content" then click "Download Export File. (this is a must because once you revert your DB everything will be lost.)
After all of the backing up, I checked my email and went to the last know sql backup that it had sent. Uploaded that via phpmyadmin. Tested it ( Dashboard -> Security -> Database Backup -> Create Database Backup ), still no luck. So I then went to the next one. Uploaded it via phpmyadmin tested it and it now works. :)
Now comes the long tedious process, checking all the inactive plugins.
I went one by one down the list ( Dashboard -> Plugins -> Installed Plugins -> Inactive )
After clicking activate I tested the Create DB Backup and every time I tested it, it worked.
I am still baffled on why it stopped working in the first place.
But never the less, all is good now.
I hope this helps others that are having the white screen issue and DB not backing up. I know it was a pain to figure out.
