I have FileVault turned on, which means that Time Machine won't back up my data while I'm logged in. Is there any way to get my MacBook to wake once at night, say 6 AM, to start a Time Machine backup and then go back to sleep when done? This way I can log out at night when I'm done with it and it can back up my home folder's sparsebundle file.
EDIT Whoops! Didn't read that you had to be logged out... well, I'll just leave this here, hopefully a starting point.
Not sure if this is what you want but try it and let me know:
Use Terminal to wake Mac at scheduled time:
Set date as preferred. Exchange wake for sleep to put Mac to sleep at scheduled time.
UPDATE: I knew there was a way to do this with Automator: http://masonsklut.com/blog/customize-time-machine-backup-times/
