Well, I am working on testing a scheme to only allow Time Machine to run when the user is local to the Time Capsule…
Through some research, you can turn on and off Time Machine from the command line…
Turn On -Â defaults write /Library/Preferences/com.apple.timemachine AutoBackup -boolean true
Turn Off -Â defaults write /Library/Preferences/com.apple.timemachine AutoBackup -boolean false
Quick & Easy to run from the command line…
