Question

You work for manufacturing company who operate a hybrid infrastructure with systems located both in a local Datacentre and in AWS, connected via Direct Connect. Currently, all on premise servers are backed up to a local NAS, but your CTO wants you decide on the best way to store copies of these backups in AWS. He has asked you to propose a solution which will provide access to the files within milliseconds should they be needed, but at the same time minimizes cost. As these files will be copies of backups stored on-premise, availability is not as critical as durability. Choose the best option from the following which meets the brief.
Copy the files from the NAS to an S3 bucket configured as Standard class.
Copy the files to an EC2 instance with a large EBS volume attached.
Copy the files from the NAS to an S3 bucket with the Reduced Redundancy Storage class.
Copy the files from the NAS to an S3 bucket with the One Zone-IA class

Answer 1

Answer: Copy the files from the NAS to an S3 bucket with the One Zone-IA class

Explanation:

Th one Zone -IA class with S3 bucket has reduced cost but offers the same durability for which the files needs to be copied from NAS to access them faster.
