Time Machine reports error with Time Capsule while in Power Nap
Version 10.8.2 software update fixed the issue that the little lights on the dock did not reappear when waking from sleep (yeah!) but created another. I have a 2TB Time Capsule that I use with Time Machine. I typically put the MBA to sleep (because they still haven't fixed the won't sleep when lid closes if there is an external display issue). When I wake it in the morning there is an error to the effect that Time Machine could not back up to the Time Capsule because it is not formatted as Mac OS Journaled--then it offers me the opportunity to select a different drive. If I ignore the error and do nothing, Time Machine backs up properly when the MBA is awake (and sometimes when it is asleep).
