I am working with RDS and I have noticed that when I create the database it seems to create an automated snapshot.
I can understand this when the instance is being shutdown by why is one made when the database is actually created, and is there any way to stop this from happening?
This is RDS doing a backup for you. It defaults to every 30 minutes, but it can be increased up to every 3 hours. You are not able to disable this as it is core functionality for RDS's disaster recovery implementation so that the database can be restored to a 30 minute relative point in time whenever necessary.
