QuestionQ59

Reliability and Business Continuity

A CloudOps engineer configured AWS Backup to take snapshots of a single Amazon EC2 instance with one attached Amazon EBS volume. At the time of the first snapshot, the EBS volume contains 10 GiB of data. At the time of the second snapshot, the EBS volume still contains 10 GiB of data, but 4 GiB has changed. At the time of the third snapshot, 2 GiB of data has been added to the volume, bringing the total to 12 GiB.

How much total storage is needed to store these snapshots?

Explanation

Amazon EBS snapshots are incremental: the first snapshot stores the initial 10 GiB, while later snapshots store only blocks changed since the preceding snapshot. The storage required is therefore 10 GiB + 4 GiB + 2 GiB = 16 GiB.
