TimeMachineEditor is a software for Mac OS X 10.5 Leopard and Mac OS X 10.6 Snow Leopard that lets you change the default one-hour backup interval of Time Machine. You can change the interval or create a more sophisticated scheduling (see screenshot right).
This is useful if you don’t need to backup every hour and don’t want the performance penalty. This is also especially useful if you manipulate lots of data within one hour as you would spend the whole day backing up.
How does it work?
TimeMachineEditor does not modify existing system files at all (unlike versions prior to 2.5). Instead it handles its own scheduling to trigger Time Machine backups when you want them to occur. TimeMachineEditor also has its own ON / OFF switch that lets you enable / disable automatic backups.
