What approach provides the lowest cost for Amazon Elastic Block Store snapshots while allowing full data restoration?

Maintain two snapshots: the original snapshot and the latest incremental snapshot.
Maintain a single snapshot as both incremental and complete.
Maintain a volume snapshot; subsequent snapshots will overwrite one another
Archive the original and incremental snapshots to Amazon Glacier.

The correct answer is: Maintain a single snapshot as both incremental and complete.

Maintaining a single snapshot as both incremental and complete is cost-effective for Amazon Elastic Block Store (EBS) snapshots while still allowing for full data restoration. When you create a snapshot of an EBS volume, AWS uses a block-level incremental approach, meaning that only the blocks that have changed since the last snapshot are saved. This method avoids the duplication of data, thereby reducing storage costs. By maintaining just one snapshot that serves both as an incremental and a complete backup, you only pay for the storage used by that snapshot rather than having separate charges for multiple snapshots, which would increase overall costs. This approach ensures you have a point-in-time backup that can be restored quickly and efficiently while keeping your expenses to a minimum since you avoid maintaining multiple snapshots. Other methods like maintaining two separate snapshots for original and incremental data or archiving snapshots to Amazon Glacier would incur higher costs due to multiple storage fees and possibly longer retrieval times for archiving scenarios, respectively. Thus, the selected choice optimally balances cost and functionality within EBS snapshot management.
