I'm running 3.5.1
DB Backup does not seem to work. It goes into "sit and spin" mode, then gives me a blank screen.
Backup for .htaccess and wp-config seem to function normally, though .htaccess saves to my server and wp-config wants to save to my desktop. Don't know if that's normal behavior or not.
Suggestion: Have a "Backup All" button that dumps files either onto the server backup folder, or to download. Don't know if that's possible, but it would be a time saver.
