Which AWS service meets these requirements?
AWS Storage Gateway
AWS Snowcone
AWS Backup
Amazon Elastic File System (Amazon EFS)
Explanations:
AWS Storage Gateway enables on-premises applications to use cloud storage by providing a local cache, allowing seamless integration and low-latency access to cloud data while storing backups in AWS.
AWS Snowcone is a small, rugged, and secure device designed for data transfer to AWS and edge computing, but it does not provide a locally cached storage solution for continuous cloud backup.
AWS Backup is a centralized backup service for AWS resources, but it does not offer a local cache for on-premises applications; it focuses on managing and automating backups in the cloud.
Amazon Elastic File System (EFS) is a scalable file storage service for use with AWS Cloud services, but it does not provide local caching for on-premises storage needs.
