I'm glad I don't have that important data to backup. Having some important files saved in more than one cloud storage services is more than enough for me. Btw Wuala by Lacie is encrypted if your main concern is security. Also, mirroed files in your computer are not accessible until wuala starts up and log in to service. Instead of creating a new folder within your Home/User folder, it creates a new drive which is encrypted. Meaning that if your computer or hard drive is stolen, your data will still be safe.
