iCloud says my last backup was May 7th. That's when I had to erase and reset this iPad 2, after which it offered (if I recall) to do a backup and I elected Yes. Under iCloud options I definitely have it set for automatic backup. The other day I got a pop-up message upon unlocking the device that there hasn't been a recent backup and the message reminded me that backup occurs when the iPad is plugged in, on WiFi and locked. Those first two conditions are easy and the device is set to lock automatically after 2 minutes or when the cover is closed (?how does THAT work?). When the machine automatically idles out into locked state does it disconnect WiFi? No of course not! ...otherwise backups couldn't ever happen. So anyway, today I checked and still no backup since May 7th so I tried to make one happen by asking manually under Settings>>iCloud>>Backup. When I did that it said, "backing up..." and it said, "Estimated time remaining...". But then after about 30 seconds a pop-up asked for my iCloud password. Yet the machine had just asked for my iCloud password when it awoke from locked state but I'm not sure why it needs to ask or how to control that behavior. In any case I gave the correct password at start-up and then when the manual backup demanded it. But after I entered it the iPad immediately gave the message, "the last backup could not be completed". I tried again and each time the events were identical as described above, until one time I decided to tap Cancel when it asked for the password after manual call for backup. After that of course I got the error "the last backup could not be completed". And each and every time after that if I manually request a backup it would give me the failure message after only a few seconds. The iPad idled out and when I later unlocked it, it was still refusing to complete a requested backup and did not ask my password again. Did I mention that I hate the iPad? It's my wife's. You give me some suggestions but I am NOT hopeful. Thank you!
