Explain EBS snapshots and how their incremental nature affects data transfer costs and storage requirements.
EBS snapshots are point-in-time copies of EBS volumes, stored in Amazon S3. They enable disaster recovery, migration, and backup compliance. Snapshots are incremental, meaning only changed blocks since the last snapshot are saved, reducing storage costs and transfer time.
Incremental nature affects data transfer costs by minimizing the amount of data transferred during snapshot creation or restoration. As only modified blocks are copied, less data is sent across the network, lowering transfer costs.
Storage requirements are also reduced due to incremental snapshots. Instead of storing entire volume copies, only unique blocks are stored, optimizing space usage and cost-efficiency.
