mysqlpump is a very similar program to mysqldump with some extra features.

How to do it...

There are numerous ways to do it. Let's have a look at each one in detail.

shell> mysqlpump --default-parallelism=8 > full_backup.sql

shell> mysqlpump -u root --password --parallel-schemas=4:employees --default-parallelism=2 > full_backup.sql
