mysqldump is a command used to backup MySQL databases.

–opt combines many options. It is same as adding –add-drop-table, –add-locks, –create-options, –disable-keys, –extended-insert, –lock-tables, –quick, and –set-charset.

–extended-insert option will group together all INSERT operations for a table. This makes the backup file smaller and makes restoration faster. I restored a mysqldump bakcup, it take me 2 hours to restore. Same database backup with –extended-insert option take only 10 minutes to restore. If you want a separate INSERT for each row, then use –skip-extended-insert or –complete-insert option
