Add configuration options for backup

**Feature request**
It would be great to have serialization for api.

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

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

Start by locating the project's configuration handling and API serialization entry points; the issue does not name files or tests. Confirm how the backup request relates to serialization, then define and verify the `enable_serialization` option with a default of `false` and production deployment coverage.
