If deployment to a target server fails and the target environment is in an inconsistent state, or a deployment is successful but the deployed assets are not working as expected, you can use Deployer's roll back feature to undo the deployment. When you roll back a deployment, Deployer rolls back the target server to the last checkpoint generated for the project. For more information about generating checkpoints, see Generating a Checkpoint.

You can set Deployer to roll back target servers automatically or you can roll back target servers manually after deployment.
