We're in the process of POC'ing backups in AWS to S3 via DP 23.4. The GUI asks for an Access Key and Secret Key, but we have currently configured access to the S3 bucket via an IAM role assigned to the EC2 instance directly. In other words, we do not access the bucket with keys.
We can access the bucket from the Cell Manager via the AWS cli, but not the DP GUI.
So the question is, does DP support backups to S3 via IAM roles vs Keys?
