When I want to dump the tables and create a .sql backup in phpmyadmin, what options should I choose? The checkbox options are
-Add 'drop table'
-Complete inserts
-Extended inserts
-Use backquotes with tables and fields' names

Also, should I choose
-structure only
or
-data only
or
-structure and data

Thanks!
