On Windows this is relatively easily scriptable with WinSCP ( scripting documentation ). This method greatly speeds up transfer, makes it secure, requires no plugins server-side, … Read more
It only affects the output of your MySQL dump in the file that is created. It isn’t necessary. It is just there so that if you import the created dump file into a database that already has a table with the same name, it will drop that table and then add the new table in … Read more
