TimeMachineEditor Mac

TimeMachineEditor is a software for Mac OS X 10.5 Leopard that lets you change the default one-hour backup interval of Time Machine.
You can change the interval or decide to make a backup once a day, once a week or once a month.

This is usefull if you don’t need to backup every hour and don’t want the performance penalty. This is also especially usefull if you manipulate lots of data within one hour as you would spend the whole day backing up.
