Previously, snapshot storage was billed on the total size of each snapshot, leading to higher costs for customers maintaining multiple backups. The updated model charges only for unique data blocks across snapshots, lowering expenses especially for disaster recovery and testing scenarios.
This change applies automatically to existing and new manual snapshots on Serverless and RG instances across AWS commercial and GovCloud regions. It allows more frequent snapshotting to improve recovery objectives without proportionally increasing costs, aiding robust data protection strategies.
