Change frequency of Time Machine back ups on OSX

By | 21/12/2019

Create a new plist called com.apple.backup-auto.plist in ~/Library/LaunchDaemons

Add the following:

Label com.apple.backupd-auto ProgramArguments /System/Library/CoreServices/backupd.bundle/Contents/Resources/backupd-helper -auto StartInterval 259200 RunAtLoad KeepAlive

The 259200 is the time in seconds between backups – i.e. 259200 seconds is 3 days.
