cchecked them out, seems like a good low priced solution but am left wondering if an ipad can be backed up using this method?
Not sure I've ever heard of an online iPad backup solution. But, if your iPad is backed up to your computer, and your computer is backed up to whatever, then your iPad is backed up.
Secure in terms of data redundancy or shielded from malicious intent? You'll find plenty of the former...
I have a small machine with a 1tb drive, and an abyss webserver instance. It's hooked up to the network and backs me up. I have a vpn server, and I link up to that and so to my content when I'm away. It's all secure and safe at home. OK, it's no cloud solution, but at least I know it's not on a server/storage place I don't know about. For minor stuff - dropbox.
