disable Time Machine scripts
All you need to do is just toggle off time machine. The scripts are for people that want to inherit an old backup folder when they continue to use time machine. 

See tmutil inheritbackup command line tool for details and the manual page.

Can I inherit a Time Machine backup if I clone my HD?



  Inheriting is typically only one step in the process of configuring a backup for use by a machine. You may also need to use setdestination, associatedisk, or both, depending on the situation.
