I leave all of my data on My Storage so I don't worry about backing up too much. Every so often I will move the pictures onto my PC into Dropbox for safe keeping, and the rest of the files can be easily dragged and dropped into a folder on the desktop. Email, contacts, calendar etc are synced with Google Sync (if you use Gmail). There are backup programs out there like SPB Backup but I don't see the point in paying $30 for something that I can easily do myself. My Phone and PIMBackup are also good free solutions but I only use the latter now.
