I back-up my 3rd Generation iPad under iOS7.0.4 (11B554a) using a USB cable connected to my iMac which runs under Mavericks OSX.10.9.1 Build 13B42. I back-up via iTunes v11.1.3 (8) 64-bit using both options: "iCloud, Backup the most important data on your iPad to iCloud" and "This computer, A full backup of your iPad will be stored on this computer". Progress bars move as expected so my assumption, without any real cast-iron proof, is that the back-ups are working and yet, after backing up I get an error message. Today's stated: "iCloud back-up, This iPad hasn't been backed up in 9 weeks. Back-ups happen when this iPad is plugged in, locked! and connected to wifi" on my home screen and in the middle of my browser which was the first app I went to after backing up. But surely I have just backed up? In the absence of any grey paint which I could watch dry - I watched it do it. (Maybe I should get out more and get a life!) What is going on? Are my back-ups taking place and if not why not? If they are, then why am I getting the error messages? How can I check both my iCloud and iMac to see if and when back-ups have taken place? Many thanks in advance.
