Question

Now that you have data in your MySQL relational database for the business, you will perform a backup of the data in the database and restore it to a database with a different name. You should review the information in the Module 04 lecture that described backing up using the mysqldump program. Also, you may want to refer to the following MySQL documentation: Requirements For this assignment, complete the following requirements: Take screen shots to show your accomplished work for each of the following sub-steps: Back up all the tables and data in your project database into a .sql file using mysqldump. Modify the .sql back up file to create and use a new database. Restore the tables and data from the .sql back up file into a new database. Prove that all the tables and data from the .sql back up file have been restored into the new database.

Answer 1

To back up and restore a MySQL database, one uses the mysqldump utility to create a .sql file, modifies this file to refer to a new database, and then imports the .sql file into that new database. Verification can be done through MySQL queries to ensure all data has been correctly restored.

Step-by-step explanation:

The question concerns the process of performing a backup and restore of a database using MySQL tools. A relational database managed by MySQL can be backed up into an SQL file using the mysqldump program. To accomplish this, follow these steps:

1. Use the mysqldump command-line utility to export the database to a .sql file. For example, mysqldump -u username -p database_name > backup.sql, where username is your MySQL username and database_name is the name of your database.
2. Edit the resulting .sql file and change the line that specifies the database name to create and use a new database. You may need to add a line that reads CREATE DATABASE IF NOT EXISTS new_database; and USE new_database; to change the database context.
3. Restore the data to a new database by importing the .sql file. This can be done with the command: mysql -u username -p new_database < backup.sql.

After the restoration process, you can verify that all tables and data have been restored by checking the new database, using queries such as SHOW TABLES; or SELECT * FROM table_name; to confirm the presence and integrity of the data.
