Question
A company is using an Amazon Aurora MySQL DB cluster that has point-in-time recovery, backtracking, and automatic backup enabled. A CloudOps engineer needs to be able to roll back the DB cluster to a specific recovery point within the previous 72 hours. Restores must be completed in the same production DB cluster.
Which solution will meet these requirements?
- A. Create an Aurora Replica. Promote the replica to replace the primary DB instance.
- B. Create an AWS Lambda function to restore an automatic backup to the existing DB cluster.
- C. Use backtracking to rewind the existing DB cluster to the desired recovery point. Correct
- D. Use point-in-time recovery to restore the existing DB duster to the desired recovery point.
Explanation
Backtracking allows you to roll an Aurora MySQL DB cluster back in time to a specific point within the last 72 hours without creating a new database or replica, thus meeting the requirement of restoring within the same production DB cluster.
