Restore Database using Binary Log for Point-In-Time Recovery

Write a MySQL command to apply binary logs to restore a database to a specific point in time.

Solution:

# This command restores the MyDatabase database to a specific point in time using binary logs
# mysqlbinlog reads the binary log file mysql-bin.000001
# --stop-datetime="2025-02-15 12:00:00" specifies to stop applying changes after this timestamp
mysqlbinlog --stop-datetime="2025-02-15 12:00:00" mysql-bin.000001 
# The | pipe sends the extracted SQL statements to the mysql client
# mysql -u root -p applies the changes to MyDatabase, prompting for the root password
| mysql -u root -p MyDatabase

Explanation:

Purpose of the Query:

To perform a point-in-time recovery using binary logs.
Demonstrates how to apply changes up to a specific date and time.

Key Components:

mysqlbinlog : Utility to process binary log files.
--stop-datetime : Specifies the cutoff point for the recovery.
Pipe the output into the mysql client for execution.

Real-World Application:

Critical for recovering from accidental data deletions or corruption up to a defined moment.

Note:

Verify the datetime format and cutoff point carefully.
Ensure binary logs are intact and available for the recovery process.
