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 com.apple.backupd-auto 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/com.apple.backupd-auto 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 com.apple.backupd-auto is as follows
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

    <key>Label</key>

    <string>com.apple.backupd-auto</string>

    <key>Disabled</key>

    <true/>

    <key>ProgramArguments</key>

    <array>

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

        <string>-auto</string>

    </array>

    <key>LaunchEvents</key>

    <dict>

        <key>com.apple.time</key>

        <dict>

            <key>Backup Interval</key>

            <dict>

                <key>Interval</key>

                <integer>3600</integer>

                <key>MaintenanceWakeBehavior</key>

                <string>Once</string>

            </dict>

        </dict>

    </dict>

    <key>RunAtLoad</key>

    <false/>

    <key>KeepAlive</key>

    <false/>

    <key>EnableTransactions</key>

    <true/>

</dict>

</plist>

    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.
