A common issue Mac users have with Apple's Time Machine tool (tool for backing up and restoring data on your computer) is that it lacks the ability to schedule backup tasks based on your needs. Instead, it automatically backs up your data at every 60 minutes, potentially slowing down the performance of your system. For this reason, utilities like TimeMachineEditor were created: to offer you more scheduling options.
The tool features easy-to-configure settings, requires minimum interaction, and uses a very small amount of CPU resources while operating on your Mac. You can choose between 3 scheduling profiles: at a certain interval of time, when your Mac isn't active or on specific days of the week at a defined hour.
In my testing, I used all 3 scheduling profiles and the utility worked as advertised.
The most important advantage of using this tool is that it can trigger backup tasks even while your Mac is in Sleep mode.
In conclusion, if you're looking for a tool to schedule your Time Machine backup session, then this is the program for you. It's effective, very simple to handle, and comes without a price.
