MySQL Backup and Restore: Restore Databases Tutorial

Restoring from SQL Dump Files

The most common way to restore a MySQL database is by importing an SQL dump file created by mysqldump or similar tools. This file contains SQL statements to recreate database objects and insert data.

To restore, you use the mysql command-line client to execute the dump file.

• Ensure the target database exists or create it before restoring.
• Use appropriate user credentials with sufficient privileges.
• Import the dump file using the mysql client.

Restoring Using Binary Logs for Point-in-Time Recovery

Binary logs record all changes to the MySQL database and can be used to restore data to a specific point in time after restoring a full backup.

This method is useful for recovering from accidental data modifications or deletions.

• Restore the last full backup first.
• Apply binary logs using mysqlbinlog utility to replay changes up to the desired time.
