Backup Using mysqldump

Mysqldump is a command-line utility that is used to generate the logical backup of the MySQL database. It produces the SQL Statements that can be used to recreate the database objects and data. The command can also be used to generate the output in the XML, delimited text, or CSV format.

Note: By default, mysqldump command does not dump the information_schema database, performance_schema, and MySQL Cluster ndbinfo database. If you want to include the information_schema tables, you must explicitly specify the name of the database in the mysqldump command, also include the —skip-lock-tables option.

mysqldump -uroot -p  --all-databases > all-databases.sql
mysqldump -uroot -p dbname > dbname.sql
mysqldump -uroot -p dbname table1 table2 > dbname_table_1_2.sql
