Question
A company is moving to the AWS Cloud gradually. The company has multiple SAP landscapes on VMware. The company already has sandbox, development, and QA systems on AWS. The company's production system is still running on premises. The company has 2 months to cut over the entire landscape to the AWS Cloud. The company has adopted a hybrid architecture for the next 2 months and needs to synchronize its shared file systems between the landscapes. These shared file systems include /trans directory mounts, /software directory mounts, and third-party integration mounts. In the on- premises landscape, the company has NFS mounts between the servers. On the AWS infrastructure side, the company is using Amazon Elastic File System (Amazon EFS) to share the common files. An SAP solutions architect needs to design a solution to schedule transfer of these shared files bidirectionally four times each day. The data transfer must be encrypted. Which solution will meet these requirements?
Options
- AWrite an rsync script. Schedule the script through cron for four times each day in the on-premises
- BInstall an AWS DataSync agent on the on-premises VMware platform. Use the DataSync endpoint
- COrder an AWS Snowcone device. Use the Snowcone device to transfer data between the on-
- DSet up a separate AWS Direct Connect connection for synchronization between the on-premises

Explanation
AWS DataSync is purpose-built for automated, scheduled data synchronization between on-premises file systems and AWS storage services like Amazon EFS. Installing a DataSync agent on the on-premises VMware platform allows the company to continuously and reliably synchronize the /trans, /software, and third-party integration mount directories with EFS in the AWS environment. DataSync handles scheduling, monitoring, integrity validation, and bandwidth throttling natively. An rsync cron script (A) is error-prone, requires manual management, and lacks built-in monitoring. AWS Snowcone (C) is designed for batch, offline data transfer - not continuous synchronization. A dedicated Direct Connect connection (D) addresses network connectivity but does not solve the file synchronization challenge and would be expensive to provision within a 2-month window.
