    I want to wake my Mac from sleep every 3 am so that my backup runs automatically. The backup is working and scheduled, but I can't get my Mac to wake up automatically.

    One of the options in the "sleep" preferences (under "Energy saver") is "start up or wake", which I put at 2:55 am.

    I would assume my Mac would wake up and my cron job would start the backup, but it really doesnt' wake. Am I missing something?

    If you go back to System Preferences, is it remembering the setting or has it been reset to nothing?
