I created a workflow to toggle iTunes iOS device backup. Those backups often take far too much time and space and are unneeded for most of my syncs.
This is my first attempt at coding anything other than java so please forgive my crude use of code. The iTunes process will automatically be killed and then restarted so make sure you're not using it for anything important before running the workflow.
Please let me know if you find it useful
