Plenty of everyone doing it wrong, but the most WTF of all the WTFs is the backup storage.

Put your backups in S3 *versioned* storage on a different AWS account from your primary, and set some reasonable JSON lifecycle rule:

     "NoncurrentVersionExpiration": {
        "NoncurrentDays": 30,
        "NewerNoncurrentVersions": 3
     }

That way when someone screws up and your AWS account gets owned, or your databases get deleted by an agent, it doesn't have enough access to delete your backups, and by default, even if you have backups that you want to intentionally delete, you have 30 days to change your mind.
