Configure Binary Logs for Incremental Database Backups

Backup Database Incrementally Using Binary Logs

Write a MySQL command to enable binary logging for incremental backup and point-in-time recovery.

Solution:

-- This section header specifies settings for the MySQL server daemon
[mysqld]
-- This line enables binary logging and sets the base name for log files to 'mysql-bin'
log-bin=mysql-bin

Note: (Restart MySQL after making the changes.)

Explanation:

• Purpose of the Query:
• To set up binary logging for capturing incremental changes.
• This demonstrates the configuration change required for point-in-time recovery.
• Key Components:
• log-bin=mysql-bin : Enables binary logging with the specified log file base name.
• Configuration change must be made in the MySQL configuration file.
• Real-World Application:
• Allows restoring the database to a specific point in time after a backup.

Note:

• A server restart is required for changes to take effect.
• Ensure sufficient disk space for binary log files.d
