Changing the Time Machine backup interval

By default, Time Machine runs and backups up every hour. If this frequency does not suit you, you can change it. The interval is controlled in a file called "" which is here


Look for a section



I've found the editing it in a text editor makes the file go funny, so easiest of you use Property List Editor from the Developer Tools kit. Its in the applications / utilities folder

Update: you can also change the interval from the command line:

    sudo defaults write /System/Library/LaunchDaemons/ StartInterval -int 7200

makes the intervals 2 hours
