Add rate limiting for backup

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

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

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

The issue names no files, tests, or entry points. Start by locating the helper and backup code and the existing configuration handling, then determine how monitoring is expected to work for production deployments. Done should include a clearly defined monitoring behavior and the `enable_monitoring` option defaulting to `false`, with tests covering the chosen behavior.
