Tip: To seed a local drive with a Time Machine backup and then
continue your backups over the network, you just need to add a
couple of steps. Start an initial backup over the network, but abort
it after it begins copying files. Then switch the drive to a local
connection to finish the backup. After one full backup has been made,
reconnect the drive to the Mac that shares it over the network.
Use Power Nap
If you have a newer notebook Mac that came with solid-state storage
and is running Mountain Lion, you can activate a feature called Power
Nap. (For details about which models are supported, whether firmware
updates are needed, and more, see Mountain Lion: About Power Nap
on Apple's Web site.) With this feature enabled, your Mac periodically
performs a variety of background tasks even while it's asleep. One
of these tasks, which occurs only when your Mac is connected to AC
power, is backing up with Time Machine.
To turn Power Nap on or off, open the Energy Saver pane of System
Preferences. Then:
To determine whether Power Nap will function (including Time
Machine backups) while your computer is plugged in, click Power
Adapter and then select or deselect Enable Power Nap While
Plugged into a Power Adapter.
To determine whether Power Nap will function ( not including
Time Machine backups) while your computer is running on battery
power, click Battery and then select or deselect Enable Power Nap
While on Battery Power.
Your selection takes effect when your Mac next sleeps.
