Is it possible to have different backends per stack?. Lets say we store our state in S3 but want to keep dev/prd in different buckets. Can we add :

backend:
  url: <s3://xxxx>

To each stack settings file?.

no it's not possible. there's an enhancement ticket requesting it as a feature though https://github.com/pulumi/pulumi/issues/10039
