New .csv files are added daily from various data sources to a central on-premises storage __cpLocation. The company wants to continue to support the legacy application while users learn AWS analytics services. To achieve this, a solutions architect wants to maintain two synchronized copies of all the .csv files on-premises and in Amazon S3. Which solution should the solutions architect recommend?
