Improve routes performance

**Description**
Currently routes lacks proper backup support.

**Proposed solution**
Add configurable backup with sensible defaults.

**Priority**: Low/Medium

No files, tests, or entry points are named. Start by locating the current route handling and configuration entry points, then determine how routes are backed up and what configurable defaults are appropriate; done means backup behavior is configurable, uses sensible defaults, and the routes performance concern is addressed.
