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.

ADDED

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.

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:

setup

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

tab 1

tab 2

tab 3

Time Machine Backup Scheduler does scheduling backup:
