Feature Idea: disable Time Machine during backups

I clone my 1TB TM drive nightly to another 1TB drive. I've got two shell scripts that I set in SD to run as pre and post backup scripts:

The first I named tm_disable.sh which contains only this line of code:

defaults write /Library/Preferences/com.apple.TimeMachine "AutoBackup" -boolean no

...and the other is tm_enable.sh with this line:

defaults write /Library/Preferences/com.apple.TimeMachine "AutoBackup" -boolean yes

It works with 10.5 and 10.6... I put the scripts in a directory on my source TM volume - and they get backed up too
