You are working for a data management company which uses AWS platform to manage the data for various customers. They are using AWS EBS backed EC2 instance with “Delete EBS volume on termination” checked. EC2 instances are used to run datastreamingapplicationwhich generates logs and are stored on EBS volumes. The log files are critical for auditing purposes. How would you protect the data stored on EBS volumes from accidental terminations of EC2 instances?
 

Answer options:

A.Every EBS volume will have a daily EBS snapshot created automatically by AWS.
B.Setup a Data LifeCycle Manager policy scheduler to create EBS snapshots for your EBS volumes.
C.When EC2 instance is terminated, it automatically creates a snapshot of EBS volume and then deletes the EBS volume.
D.Write a custom script on your EC2 instance and schedule it to back up the data onto AWS S3.

Answer: B
You can back up the data on your Amazon EBS volumes to Amazon S3 by taking point-in-time snapshots. Snapshots are incremental backups, which means that only the blocks on the device that have changed after your most recent snapshot are saved
