That article appears to be about a year old. I will expand on Ken's post with this list of items that are currently backed up from that link and add some emphasis of my own:
* The list of apps you've installed on your phone. * Your call history. * Your theme colour. * The accounts you've set up on your phone. * Your Internet Explorer favourites. * Settings from around your phone, including photos, messaging, email and accounts, location, Internet Explorer, lock screen, Speech and more. Notes * Your phone will wait for a WiFi connection to automatically save backups. If you don't connect to WiFi for a week, any changes to your App list and settings will be saved using a mobile data connection. * Backup saves the apps on your phone, but it doesn't save any data associated with the apps. * Start will reset to its default set of pinned Tiles when you restore. So for me it now backs up the more important bits that may have been lacking a year ago. My WP8 (HTC Windows Phone 8X) has had a firmware upgrade or two in that time. But I do find it a bit disappointing that user application data and changes to pinned Tiles are not backed up.

Looking further into the WP8 backup, this paints an even worse picture than I'd imagined: http://allaboutwindowsphone.com/features/item/16663_When_is_a_backup_not_a_backup_.php
