HTC Backup uses your Dropbox storage to keep your content. The types of content that it can back up and restore include the following:

Home screen settings (These include your Home screen feed settings, widgets, and Home screen layout.)
Accounts and passwords (Except for some accounts (such as Facebook and Google), HTC Backup can store the login credentials of the email and social network accounts that you've set up on your phone.)
Apps and settings (These include your web bookmarks, personal dictionary (of the keyboard), Wi-Fi networks, settings in the TV app (such as favorites and reminders), apps you've installed, and over 150 other settings.)

How to I backup my contacts then?

Make them all Google contacts and they backup to your gmail.
