The key word that soon frustrated many users is constantly. You simply turn it on and forget it, resting easy that your drive is constantly being backed up in case of drive failure. When Apple introduced Time Machine in OS X 10.5 Leopard, it was a glorious day for everyone who struggled with overly complicated backup software. In the code above, I have it set to two hours, but you can enter any amount of seconds you wish, such as 10800 for three hours, or 14400 for four hours, etc. The number at the end of that line is the amount of seconds between backups. Open Terminal and paste the code below into the Terminal window and hit the Return key (make sure you copy the exact text below.) Enter your Admin password when it asks and hit return again: sudo defaults write /System/Library/LaunchDaemons/-auto StartInterval -int 7200 Fortunately, you can still do it using the Terminal app in your Utilities folder. And for those who actually do alter numerous files (especially large ones) every hour, your probably don’t want the system using resources for backups every hour.Īpple really should offer a way to adjust the backup time in the System Preferences, but they don’t. For many people, this simply isn’t necessary. Donations contribute to the web hosting and developer account fees.By default, Apple’s Time Machine performs backups every hour. TimeMachineEditor is totally free to use. Alternatively the tmectl command line tool can be used with the “uninstall” argument. Just select the “Uninstall.” command located under the application main menu. New snapshots are created every time a regular backup is made (snapshots are used as the data sources for the backups). The lifetime of snapshots is not well defined but they usually live no longer than 24 hours. Since they are local they do not protect against a disk crash but can be useful if the machine goes away from the backup disk for awhile. They are very fast to make, stored on the local disk and provide additional restoration points. Time Machine will coalesce and discard backups as described in System Preferences > Time Machine. TimeMachineEditor does not change that, it is handled by Time Machine. How does TimeMachineEditor preserve/discard backups? If you have an Apple Silicon machine, Power Nap is always enabled. If you are using a laptop computer, make sure you are on the “Power Adapter” tab, as this feature only works when connected to AC power. TimeMachineEditor supports Power Nap which you can enable in System Preferences > Energy Saver. Will it back up while the machine is sleeping? You just need to use the application when you want to change the settings. Do I need to keep the application running or launch it at login time? Doing this disables the default one-hour scheduler which is what you want since you will now be using TimeMachineEditor to schedule the backups. FAQ Should I disable automatic backups in System Preferences > Time Machine? Just fire up the command without any argument to see its usage. The tmectl command line tool allows to print and modify settings, enable/disable the scheduler and uninstall the application. TimeMachineEditor does not make changes to your system, it simply runs as an alternative scheduler to start your backups. TimeMachineEditor starts backups in Time Machine when it is most appropriate, the whole backup process is still handled by Time Machine. If you are a Homebrew user: brew install -cask timemachineeditor How does it work? TimeMachineEditor 5.2.2 (2023, February 16) - macOS 10.13 or newer For example you might be frequently creating or modifying files which would cause long-running backup operations throughout the day. This is useful if you don’t need to backup every hour and don’t want the performance penalty. You can choose an interval or create other types of scheduling (see the screenshots below). TimeMachineEditor is a software for macOS that starts backups in Time Machine at particular times.
