Consider deprecating old routes API

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

**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 files, tests, or entry points. Start by clarifying whether the request concerns deprecating the old routes API or adding store backup through enable_backup, then locate the relevant configuration and backup behavior. Done should include an agreed scope, default behavior, and tests for the production use case.
