Amazon RDS enhanced snapshot reporting by providing a ‘FullSnapshotSizeInBytes’ field in the DescribeDBSnapshots API and console display. This metric sums all blocks constituting a snapshot, both newly stored and referenced from prior snapshots, thus showing the full data footprint.

Since RDS snapshots are incremental, previous interfaces showed only newly changed block sizes per snapshot. This enhancement aids customers in better understanding storage usage for database snapshots across all AWS commercial regions, accessible through console, CLI, and SDKs.
