Last update on September 25 2025 07:23:37 (UTC/GMT +8 hours)

Simulating a Disaster Recovery Drill

Write a SQL query to simulate a disaster recovery drill by restoring a database from backups.

Solution:

-- Simulate a disaster recovery drill by restoring the database.
RESTORE DATABASE MyDatabase
FROM DISK = 'C:\Backups\MyDatabase_Full.bak'
WITH NORECOVERY;

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 simulate a disaster recovery drill by restoring a database from backups.

Key Components :

RESTORE DATABASE: Restores the full backup first.
RESTORE LOG: Applies transaction log backups to achieve point-in-time recovery.
WITH STOPAT: Specifies the exact point in time to restore to.

Why Simulate Disaster Recovery?:

Simulating recovery drills ensures that backup and restoration processes work as expected.
It identifies potential issues before an actual disaster occurs.

Real-World Application :

In enterprise environments, regular drills validate disaster recovery plans.

Notes:

Perform drills in a non-production environment to avoid disrupting operations.
Document lessons learned and update recovery procedures accordingly.
Communicate with stakeholders before initiating drills.
