How to Restore a SQL Database Using Point-in-Time Recovery

Restoring a Database Using Point-in-Time Recovery

Write a SQL query to restore a database to a specific point in time using transaction log backups.

Solution:

-- Restore the transaction log backup to a specific point in time.
RESTORE LOG MyDatabase
FROM DISK = 'C:\Backups\MyDatabase_Log.trn'
WITH STOPAT = '2023-10-01T12:00:00', RECOVERY;

Explanation:

• Purpose of the Query :
• The goal is to demonstrate how to restore a database to a specific point in time using transaction log backups.
• Key Components :
• WITH STOPAT: Specifies the exact point in time to restore to.
• WITH RECOVERY: Brings the database online after restoration.
• Why Use Point-in-Time Recovery?:
• Point-in-time recovery ensures precise restoration to a specific moment, minimizing data loss.
• It is critical for recovering from accidental deletions or updates.
• Real-World Application :
• In e-commerce systems, point-in-time recovery restores orders to their state before an error occurred.

Notes:

• Ensure transaction log backups are available for the desired time range.
• Test point-in-time recovery procedures regularly.
• Validate timestamps to avoid errors.
