D. Use AWS Storage Gateway and configure a stored volume gateway Can not use AWS Snowball because of "maintaining local access to all the data" Keywords: store all your data locally --- Volume Gateway: The gateway supports the following volume configurations: Cached volumes – You store your data in Amazon Simple Storage Service (Amazon S3) and retain a copy of frequently accessed data subsets locally. Cached volumes offer a substantial cost savings on primary storage and minimize the need to scale your storage on-premises. You also retain low-latency access to your frequently accessed data. Stored volumes – If you need low-latency access to your entire dataset, first configure your on-premises gateway to store all your data locally. Then asynchronously back up point-in-time snapshots of this data to Amazon S3. This configuration provides durable and inexpensive offsite backups that you can recover to your local data center or Amazon Elastic Compute Cloud (Amazon EC2). For example, if you need replacement capacity for disaster recovery, you can recover the backups to Amazon EC2.

D. AWS Storage Gateway - "stored volume" gateway https://docs.aws.amazon.com/storagegateway/latest/userguide/StorageGatewayConcepts.html Stored volumes architecture: 1. Store primary data locally, while asynchronously backing up that data to AWS. 2. Stored volumes provide on-premises applications with low-latency access to their entire datasets. 3. Also provide durable, offsite backups.

By leveraging AWS Storage Gateway with a cached volume gateway configuration, you can maintain local access to your data while securely transferring it to AWS for backup purposes. This solution provides a seamless integration between your on-premises environment and AWS cloud storage, allowing for efficient and secure data backup.

'D' gives you access to all the data on premises while it asynchronously backs up on AWS

Going with D here, agree with what DrCloud said

C local, cached

In the cached mode, your primary data is written to S3, while retaining your frequently accessed data locally in a cache for low-latency access. In the stored mode, your primary data is stored locally and your entire dataset is available for low-latency access while asynchronously backed up to AWS.

C....Local access is the key and its volume as well

Key catch - wants to maintain local access to all the data while it is backed up on AWS Volume Gateway Cached Mode - Primary data stored in S3 with frequently accessed data cached locally on-prem (not all data but only frequently accessed locally) Volume Gateway Storage Mode - Asynchronous replication of on-prem data to S3

Maintain all local copies of the data in on premises D

Its C for usre cache volume for local access

D for sure

A and B are out since the qn doesn't state the amount of data invovlved "access to all the data" D is the answer

Ans=D. Use AWS Storage Gateway and configure a stored volume gateway. Run the Storage Gateway software appliance on premises and map the gateway storage volumes to on-premises storage. Mount the gateway storage volumes to provide local access to the data. https://docs.aws.amazon.com/storagegateway/latest/userguide/WhatIsStorageGateway.html

C....Local access is the key

DDDDDDDDDDDDD

D is answer
