You are designing a database named DB1. Changes will be deployed to DB1 every Wednesday night. You need to recommend a strategy to deploy the changes to DB1. The strategy must meet the following requi

Performing a copy-only database backup allows for restoration, but the process of restoring a full backup is typically much slower than reverting a database using a snapshot, thus not meeting the 'undo quickly' requirement as efficiently.

Although creating a database snapshot is a technically correct and effective strategy for meeting the specified requirements, this option is a duplicate of choice C, which is explicitly designated as the correct answer.

Creating a database snapshot before deploying changes enables a significantly faster rollback to the database's pre-change state compared to restoring a full backup, directly addressing the 'undo quickly' requirement. Database snapshots also do not interfere with the regular backup operations of the source database, making it a non-disruptive solution.

Performing a full database backup can potentially disrupt subsequent differential backups by resetting the differential base, and restoring from a full backup is generally slower than reverting using a snapshot, failing to meet the 'undo quickly' requirement optimally.
