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.
