TimeMachineEditor lets you change the one-hour interval of Time Machine backups. You can change the interval or decide to make daily, weekly and monthly backups. TimeMachineEditor does not modify existing system files at all. Instead it handles its own scheduling to trigger Time Machine backups when you want them to occur.
