Which AWS Storage Gateway configuration meets the requirements of maintaining low-latency access and off-site backup?

1. Gateway-Cached volumes with snapshots scheduled to Amazon S3

2. Gateway-Stored volumes with snapshots scheduled to Amazon S3

3. Gateway-Virtual Tape Library with snapshots to Amazon S3

4. Gateway-Virtual Tape Library with snapshots to Amazon Glacier

The correct answer is: Gateway-Cached volumes with snapshots scheduled to Amazon S3

The Gateway-Cached volumes configuration is particularly effective for maintaining low-latency access to frequently accessed data while also providing a robust off-site backup solution. In this setup, the primary data is stored in Amazon S3, and a small portion, or cache, of the most frequently accessed data is kept locally on premises. This design helps achieve low-latency access since the local cache allows quick retrieval of frequently used data without the need for constant remote access to S3. Additionally, regular snapshots of the cached volumes can be scheduled to automatically back up the data to Amazon S3, ensuring that there is a streamlined off-site backup solution that leverages the durability and availability of S3 storage. This configuration strikes a balance between performance and secure data storage by keeping high-performance operations localized while still taking advantage of cloud storage for scalability and backup. The other configurations, while each serving their purposes, either compromise on low-latency access or optimize for different use cases that may not align with the requirements outlined.
