Call the script “backup_manual.cmd” and run it once a week, once a term or once a year if you like.  It will save data in a ‘year’ folder i.e. “2015” which will be overwritten each time the script is run.  The next year, it will start overwriting next year’s folder.

Note: You will need sufficient free space on your USB hard disk as each year a new backup set is created.
