    Hi Guys & Girls,

    Have a small issue, which I was wondering if anyone else had come across.

    I have a rMBP and 10.8.1, and am noticing that when it goes to sleep, whilst it fetches emails etc periodically, it doesn't seem to back up to the time capsule that i have at home (even when its on A/C Power...

    Any ideas?

    Head into System Preferences > Time Machine and see if there are any error messages. If you have the TM menu bar icon enabled, attempt a manual backup and see if that is successful.

    You'll also want to go into TM options and see if "Backup while on Battery Power" is selected or not.

    I have got backup whilst on battery power enabled, and when the computer is switched on it backs up fine, no issues, just doesn't do it whilst in powernap....

    As far as I know powernap will not power external USB devices. It works only if you backup flash storage over WiFi. It will not backup from or to any revolving media.
