Answer:

A. Take regular EBS snapshots .

Explanation:

- $B$ is incorrect. It lacks durability of EBS volumes.

- $C$ is incorrect. ECT Instance stores are not durable.

- $D$ is incorrect. Mirroring across EBS volumes is pargely inefficient.

-Since EBS snapshots only saves snapshots of the most recent device changes, a great deal of time and memory is saved. Also, only data unique to any particular snapshot is removed in cases of deletion.
