What is the difference between RDS backup and snapshot?
First backup is a full backup, while the others are incremental.

Amazon EBS Snapshots are incremental, storing only the changes since the last snapshot, making them cost effective and ideal for frequent backups. You can use tools such as AWS Cost Explorer to track snapshot usage and spend, and further optimize storage costs as needed.
Why snapshot is not a backup?
So, snapshots are not backups because they are not copies. They don’t take up much space individually, but their total volume can grow, especially if there are lots of deleted blocks/files, and so suppliers usually limit the amount of snapshots that can be retained.
