I must say that Time Machine is pretty useful, and it saved me a couple of times. The problem is it seems running all the times, and slowing the system down pretty often.

Is there a way/tool to run Time Machine only once a day, say 02:00am. And, it would be better if the Time Machine wakes the Mac up and after it's done with the backup, go to sleep again.


I installed and ran the 'Timemachine Editor' as advised, but it doesn't work. I mean, even though I set the timemachine to run 02:00am, it just runs every hour.

I use Snow Leopard 10.6.4. Is there anything that I missed?

As you said that Time MAchine Editor didn't work fine for you then I search in web and find : TimeMachineScheduler it disables the automatic backup function of Time Machine and installs its own launchd daemon.

Time Machine Editor (free software) allows you to specify a schedule for Time Machine to run. it changes the one-hour interval of Time Machine backups. You can change the interval or decide to make daily, weekly and monthly backups.

Thanks! It's a great help. – prosseek Sep 11 '10 at 20:34

Use Carbon Copy Cloner instead. It uses the same underlying stuff as Time Machine.

You can set a scheduled task for 2am that does an Incremental Backup with the "archive deleted or modified files" option checked.

Here's what mine looks like... create something like this:


Then click save task. It should look like this in the saved tasks window:

tab 1

tab 2

tab 3
