 * I do mysql backups frequently, and I ran one last week, and just ran one again
   this morning. Despite that new blog posts and comments had taken place since 
   my last backup, today’s mysql backup was actually smaller (this is a standard
   mysql with no compression). I noticed during my first backup, when looking over
   the resulting file that WordPress contains a lot of table data that appears to
   be system-oriented or other things unrelated to my categories, comments, posts,
   users, etc. Does WordPress update the data in these tables automatically, whenever
   you login to the dashboard, for instance, that might explain why my backup was
   10% smaller today than last week, despite more information on my end?
