3. Backing Up MySQL Data (Copy Method) Database Copy Procedure 1.Shut down the MySQL service 2.Copy data files to backup location http://localhost/phpmyadmin/ http://localhost/phpmyadmin/ On Windows: C:\Program Files\MySQL\MySQL Server 5.1\data\database_name C:\xampp\mysql\data On Unix: /var/lib/mysql

4. Restoring MySQL Data (Copy Method) Restoring Database Procedure: 1.All files must be replaced in the same directory from which they were backed up. 2.Restart database service

5. Copy Method Advantages/Disadvantages Advantages: 1.Fast 2.Easy Disadvantages 1.Not recommended for moving or upgrading databases 2.All or nothing data restoration

6. mysqldump Backup (Preferred Method) Creating mysqldump Backups Description: The SQL commands used to create the tables and the data can be redirected to a file. That file can then be used to rebuild the database. Syntax: mysqldump –u user –p db_name mysqldump –u user –p db_name table_name

7. Creating mysqldump Backups Examples: Backup one database: mysqldump –u root –p notedb > notedb_backup.sql Backup one database table: mysqldump –u root –p notedb notecard > notecard_backup.sql

8. Creating mysqldump Backup (cont.) Examples: Backup all databases: mysqldump –u root –p –-all-databases > full_backup.sql Backup Schema w/o Data: mysqldump –u root –p -–not-data > schema_only.sql Backup Data Only w/o Schema: mysqldump –u root –p -–no-create-info > data_only.sql

9. mysqldump Advantages/Disadvantages Advantages: 1.SQL generated can be used to migrate database to a new version or architecture 2.Can be used for a partial backup/restore 3.Scriptable Disadvantages 1.Not point and click Note: Similar capability is available via phpmyadmin

10. Restoring mysqldump Backups Restore databases created with --all-databases : mysql –u root –p < full_backup.sql Restore only one database: mysql –u root –p -D notedb < notedb_backup.sql

11. Working with CSV Data in MySQL Exporting Database in CSV Format Create separate files for each table in database: mysqldump –u root –p --no-create-info --tab=csvDir --fields-terminated-by=',' notedb Importing CSV into Database: mysqlimport –u root –p --fields-terminated-by=',' notedb notecard.csv Note: The filename prefix determines the table name
