Which AWS service will meet these requirements?

Explanations:

AWS Database Migration Service (AWS DMS) is primarily designed for database migration and replication, not for transferring large amounts of unstructured data or handling intermittent connectivity issues.

AWS DataSync is used for transferring data between on-premises storage and AWS, but it requires continuous connectivity and is not ideal for scenarios with intermittent connectivity and large datasets like 10 TB.

AWS Backup is a service focused on creating backups for AWS resources and does not address the needs of transferring large amounts of local data to AWS or handling intermittent connectivity.

AWS Snowball Edge is specifically designed for transferring large volumes of data (like 10 TB) from local storage to AWS, especially in environments with intermittent connectivity. It allows for offline data processing and secure data transfer.
