There is one way to back up to both iCloud and your computer. First, set up automatic iCloud backup. Then, whenever you plug in your iOS device, right-click on its name in the iTunes sidebar and hit 'backup'. It will do a one-time backup to your computer.
It's not perfect, but it works really well for me. Daily automated backups to the cloud + backups on my computer whenever I update the OS or upgrade devices.
