I am running Mountain Lion 10.8.2.


I have been tinkering with modifying backup interval for Time Machine.  In order to do this I have been attempting to edit the plist file.  To change it I have read that all that is required is to do the following.


sudo defaults write /System/Library/Launch Daemons/ StartInterval -int 1800

However there is no StartInterval in the plist file.  So how is the above write command supposed to work?
Contents of the is as follows
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "">

<plist version="1.0">








        <string>/System/Library/CoreServices/backupd.bundle/Contents/Resources/backupd- helper</string>







            <key>Backup Interval</key>

    Are you doing this just for fun? Because there's already a free utility for this - TimeMachineEditor 3.0.2.

    Yes. I am now and have been using it. I like my backups once a day at a specific time so I don't add too much to the backup drive. The redundancy isn't needed. Mostly I am testing Time Machine. It isn't my preferred backup tool.
