Here at Remind we maintain a set of tools and Python libraries to copy and verify AWS RDS DB Instance and Cluster Snapshots.
dbsnap-copy:- AWS RDS allows a maximum of 35 "automatic" daily snapshots. We wrote this tool to copy "automatic" snapshots as "manual" snapshots. We also use this tool to increase our disaster recovery fitness by copying snapshots to remote regions.

dbsnap-verify:- We use this tool to automate testing RDS snapshot restore process. This gives us confidence that we have the ability to recover from our database backups in case of a disaster.
