As of 2021-06-22, there isn't a cli method to "roll-back" a sam deploy stack. There is an open issue about it here.

At the moment, my solution is to ensure that I'm doing a proper release in Git, then I can checkout any previous version, build and deploy (updating the live stack accordingly, not rolling-back per-se.)

Because sam deploy is ultimately doing a cloudformation deploy, failure/rollback is always a possibility at the stack level. That also means that you can use aws cli to investigate and manipulate stack deployed via SAM just like any other.

If you want to rollback to a previous version of the lambda

You can publish a new version of your lambda every time you deploy using sam cli. if you add the "AutoPublishAlias" property to your lambda function.

Example:

  HelloWorldFunction:
    Type: AWS::Serverless::Function
    Properties:
      Handler: cmd/lambdas/hello-world/app.lambdaHandler
      CodeUri: src/
      Runtime: nodejs12.x
      AutoPublishAlias: live
      Events:
        CatchAll:
          Type: Api
          Properties:
            Path: /hello-world
            Method: GET

Then anytime you want to rollback you can pick a previous version from the interface enter image description here
