[MacOS] Change Time Machine’s Backup Intervalls

We all know Time Machine is handy (at least since update 10.5.2 which fixed tons of issues). But one thing is not very handy: we usually cannot change the intervall of the backups. Before I will show you a simple solution please do me the favor to tell me:

Where do you come from?

Do the following (I assume you’re logged in with your normal user account):

  • open terminal
  • for 30 minutes intervalls enter this:
    sudo defaults write /System/Library/LaunchDaemons/com.apple.backupd-auto StartInterval -int 1800
  • for 60 minutes intervalls (standard) enter this:
    sudo defaults write /System/Library/LaunchDaemons/com.apple.backupd-auto StartInterval -int 3600
  • for 6 hours intervalls enter this:
    sudo defaults write /System/Library/LaunchDaemons/com.apple.backupd-auto StartInterval -int 21600
  • for 12 hours intervalls enter this:
    sudo defaults write /System/Library/LaunchDaemons/com.apple.backupd-auto StartInterval -int 43200
  • and so on…

The simple formula is just a conversion from minutes or hours to seconds. Means: 1800 seconds = 30 minutes…
You can also go smack to the /System/Library/LaunchDaemons/com.apple.backupd-auto file and edit it using a texteditor and change the StartInterval values. But I feel like the solution above might be faster… Kudos fly to mactricksandtips.com.
