Copy-Only Backup in SQL for Independent Data Protection

Creating a Copy-Only Backup

Write a SQL query to create a copy-only backup of a database.

Solution:

-- Create a copy-only backup of the MyDatabase database.
BACKUP DATABASE MyDatabase
TO DISK = 'C:\Backups\MyDatabase_CopyOnly.bak'
WITH COPY_ONLY, INIT;

Explanation:

• Purpose of the Query :
• The goal is to demonstrate how to create a copy-only backup that does not interfere with the backup chain.
• Key Components :
• WITH COPY_ONLY: Indicates that the backup does not affect subsequent differential or log backups.
• INIT: Ensures the backup overwrites any existing file at the specified location.
• Why Use Copy-Only Backups?:
• Copy-only backups allow ad-hoc backups without disrupting the regular backup schedule.
• They are useful for testing or creating additional copies.
• Real-World Application :
• In development environments, copy-only backups create test datasets without impacting production.

Notes:

• Use copy-only backups sparingly to avoid confusion in the backup chain.
• Clearly label copy-only backups to distinguish them from regular backups.
• Avoid using copy-only backups for routine disaster recovery.
