### Describe the feature

Can we provide a way to write unprocessed messages (not able to be sent to MQTT broker due to network reasons) to a file or permanent storage? As if we use SBC(single board computer) to keep those messages in RAM it may overflow.

### Use Case

We have an RPie installed at different sites which sends us data via AWS IoT Core, sometimes network failures occur for which a team is sent to fix at the remote area which takes around 10 - 15 days sometimes memory crashes for which historical data is wiped off and sometimes device power failure occurs for which all data is lost during network outage at a site.
