A company has a business system that generates hundreds of reports each day. The business system saves the reports to a network share in CSV format. The company needs to store this data in the AWS Cloud in near-real time for analysis. Which solution will meet these requirements with the LEAST administrative overhead?

1. Use AWS DataSync to transfer the files to Amazon S3. Create a scheduled task that runs at the end of each day.
2. Create an Amazon S3 File Gateway. Update the business system to use a new network share from the S3 File Gateway.
3. Use AWS DataSync to transfer the files to Amazon S3. Create an application that uses the DataSync API in the automation workflow.
4. Deploy an AWS Transfer for SFTP endpoint. Create a script that checks for new files on the network share and uploads the new files by using SFTP.
