Here are the two commands you can run from the Mysqli Command Prompt to successfully clone a database table. In the example we will name our tables new_table_name and old_table_name where old_table_name is the table we wish to clone. This is the best way I have found to-date to create a backup of a mysqli table from the command line:
CREATE TABLE new_table_name LIKE old_table_name;
INSERT new_table_name SELECT * FROM old_table_name;
Be sure to enter line one above and press enter, then do the same with the second line.
