Time Machine Backup Interval

[fterh]

In /System/Library/LaunchDaemons/com.apple.backupd-auto.plist I have changed 3600 to 86400 (24 hours). However, right now, in Time Machine preferences, it says:

Latest Backup: 8:02 AM.
Next Backup: 9:43 AM.

And here's the really weird thing. 5 minutes ago the Next Backup was like 10+am. It just changed to 9:43 AM.

Why not just use one of the Time Machine schedulers?

As far as possible I like to avoid installing unnecessary software

But that said, I've installed Time Machine Scheduler to try.

Works like a charm for me

Alright, hope it does for me as well.

But any idea why editing com.apple.backupd.plist doesn't work? Or is it just that the changes won't be reflected in TM Preferences?

Sorry... no idea on that
I just know I prefer this solution to mucking around myself

Alright. Another thing though. In TimeMachineScheduler backup interval is set to 12 hours. According to TM my last backup was Yesterday at 7:36 PM. It's now 9:00 PM today. Clearly 12 hours has long passed.

So how come no backup was performed? If my computer happens to be switched off, then it will just skip the backup?
