Refactor config for better readability

**Feature request**
It would be great to have backup for helpers.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_backup` with default `false`.

The issue names no configuration file, helper entry point, or test. Start by locating the existing configuration definition and helper implementation, then verify how an `enable_backup` setting with a default of `false` should affect production deployments and add coverage for the disabled and enabled cases.
