iPad2 - started iCloud backup - cranked up Pages - got the lil' up arrow - got a warning that another user was deleting stuff - all Pages files are gone. What happened? And how can I prevent this from happening again? Had an iPhone 4 and iMac on the iCloud and no Pages files can be found on any of 'em. Time Machine was cranking away, but there's nothing saved there either. Any and all input mucho appreciated!?!
