Which Amazon service allows for automated backups of data stored in it?

The correct answer highlights Amazon EBS, which stands for Elastic Block Store. This service is designed specifically for use with Amazon EC2 (Elastic Compute Cloud) instances, providing persistent block storage to them. One of the key features of Amazon EBS is its ability to create automated backups through snapshots. These backups are incremental, meaning that only the changes made since the last snapshot are saved, which optimizes storage usage and cost.

When a snapshot is taken, it captures the state of the EBS volume at that specific point in time, and these snapshots are stored in Amazon S3, allowing for durability and high availability. Users can restore their EBS volumes from these snapshots or create new volumes based on them, facilitating both disaster recovery and operational resilience.

The other options, while also providing certain backup capabilities, do not focus specifically on the automated backup functionality in the same manner. For example, Amazon S3 provides versioning and lifecycle management that can also be used for backup but is primarily an object storage service. Amazon DynamoDB does offer backup features but is more oriented towards transactional database operations. Amazon Glacier, on the other hand, is intended for long-term archival storage rather than real-time data backup related to active workloads. Thus, the distinct capability of
