Your company is concerned with EBS volume backup on Amazon EC2 and wants to ensure they have proper backups and that the data is durable. What solution would you implement and why? Choose the correct answer from the options below

Answer options:

A.Configure Amazon Storage Gateway with EBS volumes as the data source and store the backups on premise through the storage gateway
B.Write a cronjob on the server that compresses the data that needs to be backed up using gzip compression, then use AWS CLI to copy the data into an S3 bucket for durability
C.Use a lifecycle policy to back up EBS volumes stored on Amazon S3 for durability
D.Use Amazon Data Lifecycle Manager (Amazon DLM) to automate the creation of snapshots taken to back up your Amazon EBS volumes.. The data is durable because EBS snapshots are stored on the Amazon S3 standard storage class

Answer – D
You can use Amazon Data Lifecycle Manager (Amazon DLM) to automate the creation, retention, and deletion of snapshots taken to back up your Amazon EBS volumes. The snapshots are automatically stored on S3 for durability.
