> Background queue, progress, pause/resume, cancel, and retention.

# Jobs

**Jobs** lists background runs: generation, evolve, walk-forward, robustness, regime, portfolio backtest, and data download/updates.

## Where each job runs

| Executor (“Where” column) | Meaning                                                      |
| ------------------------- | ------------------------------------------------------------ |
| **Agent**                 | Compute on your [TPA](/en/tpa/overview) (must be **online**) |
| **Worker**                | Server Redis worker (e.g. data downloads)                    |

If the product requires an agent and the TPA is offline, enqueue fails with a clear message → [Install and pair](/en/tpa/install).

## Statuses

Queued → Running → Done / Error / Cancelled / **Paused**.

The list auto-refreshes while jobs are active.

## Actions

| Action     | When                                                                                        |
| ---------- | ------------------------------------------------------------------------------------------- |
| **View**   | Jump to related result / context                                                            |
| **Pause**  | Only supported types (e.g. random generation). Otherwise: *This job does not support pause* |
| **Resume** | Continues from checkpoint (generate)                                                        |
| **Cancel** | Aborts the job                                                                              |
| **Retry**  | Re-queues; option to retry from scratch discarding checkpoint                               |

## Progress and ETA

Long runs show progress (% / counters). The Generator also shows ETA when the engine computes it. You can leave the page — the job stays under Jobs.

## Common types

* Generation / Evolve
* Walk-forward / Robustness / Regime
* Portfolio backtest
* Data download / Update all or selected

## Retention

Under **Settings → General → Jobs retention (days)**:

* How long to keep history (typical default **30**).
* **0** = do not auto-delete.
* Cleanup is **lazy** when enqueueing or running a job (no separate cron).

## Common issues

* Job won’t start (agent) → TPA online + Profile **Connected**.
* OOM on generate → lower workers ([Generator](/en/generator/overview)).
* Pause missing → that type does not support it.
* More: [Troubleshooting](/en/troubleshooting).
