title: Back up MySQL when DELETE query is performed
body: <p>This is quite a stretch, but I am wondering if it is possible to change MySQL's behavior so that when a <code>DELETE</code> query is performed, something else happens -- for example, the row to be deleted is added to a backup database.</p>
  
  <p>Basically, I have a WordPress site that I want to be able to recover data from. In WP, you can delete posts and put them in the trash bin first, but users and other data are deleted permanently.</p>
