+# Backup-Dashboard
+
+Proof of concept backup dashboard, intended to display backup jobs from multiple sources.
+
+```
+collectors ──POST /api/v1/ingest (API key)──▶ ┌──────────────┐
+                                              │ FastAPI +    │
+browser ──nginx (basic auth, TLS)──▶ /api/* ─▶│ SQLite       │
+        └─ static files: public/              └──────────────┘
+```
+
+- `public/`: static frontend (no build step). Add `?mock=1` to the URL to use built-in sample data.
+- `backend/`: FastAPI API backed by a single SQLite file.
+- `deploy/`: nginx site and systemd unit.
+- `collectors/`: scripts that report results from backup products ([Veeam B&R](collectors/veeam/README.md)).
+
+## Data model
+
+- **Tenant** (company) → **Job** → **Run**.
+- A job is keyed by `(tenant, source_system, job.external_id)`, so renaming a job at the source updates it instead of creating a duplicate.
+- A run has `status` (`running` | `success` | `warning` | `failed`), `started_at` and `finished_at`.
+  The dashboard's **Last Run** is the most recent `finished_at`. While a job is running it shows
+  **Running**, and Last Run still shows when the previous run finished.
+- Runs older than `BACKUP_DASH_RETENTION_DAYS` (default 90, minimum 30) are purged every 6 hours.
+
+## Reporting results (collectors)
+
+Each collector (a script on a Veeam server, a webhook relay, etc.) gets its own API key:
+
+```bash
+cd backend && python manage.py create-key veeam-acme
+```
+
+Then it POSTs one report per run. Send `running` when a run starts (optional) and the final status
+when it ends. Reports with the same `started_at` (or `run.external_id`) update the same run, and
+retries are safe.
+
+```bash
+curl -X POST https://backups.example.com/api/v1/ingest \
+  -H "Authorization: Bearer bdk_..." -H "Content-Type: application/json" \
+  -d '{
+    "tenant": "Acme Corp",
+    "source_system": "Veeam B&R",
+    "job": { "external_id": "4f1c…", "name": "File Server – Nightly", "next_run_at": "2026-10-05T22:00:00-04:00" },
+    "run": {
+      "status": "success",
+      "started_at": "2026-10-04T22:00:05-04:00",
+      "finished_at": "2026-10-04T22:47:12-04:00",
+      "message": "Job completed successfully.",
+      "size_bytes": 128849018880,
+      "details": { "repository": "REPO-01" }
+    }
+  }'
+```
+
+- All timestamps must include a timezone offset (`Get-Date -Format o` in PowerShell does this).
+- `job.next_run_at` controls the **Overdue** flag. If you omit it, the stored value is kept. If you send `null`, it's cleared.
+- `run` can be omitted to only register or update a job.
+- Unknown fields are rejected (HTTP 422), so typos in collector scripts fail loudly.
+
+## API (read)
+
+| Endpoint | Returns |
+|---|---|
+| `GET /api/v1/jobs` | All jobs with current status, `running_since`, `last_run_at`, `next_run_at` |
+| `GET /api/v1/jobs/{id}` | One job, plus the last finished run's duration, size, message and details |
+| `GET /api/v1/jobs/{id}/runs?days=30` | Run history (no messages), newest first |
+| `GET /api/v1/runs/{id}` | One run including message and details |
+| `GET /api/v1/health` | `{"status": "ok"}` |
+
+The OpenAPI schema is at `/api/v1/openapi.json`.
+
+## Authentication
+
+- **Dashboard users:** nginx basic auth over HTTPS (`deploy/nginx.conf`). Every user can see every tenant.
+  *Planned:* Microsoft 365 sign-in through [oauth2-proxy](https://oauth2-proxy.github.io/oauth2-proxy/)
+  with the Entra ID provider and nginx `auth_request`. That's an nginx-only change. The frontend
+  already tells the user to reload when a session expires (HTTP 401).
+- **Collectors:** per-collector bearer keys, checked by the app. Only a SHA-256 hash is stored.
+  To revoke one, run `python manage.py revoke-key NAME`.
+
+## Development
+
+```bash
+cd backend
+python -m venv .venv && . .venv/bin/activate
+pip install -r requirements.txt -r requirements-dev.txt
+pytest
+python manage.py --create seed-demo            # 30 days of fake history in ./backup-dashboard.db
+BACKUP_DASH_SERVE_STATIC=1 uvicorn --factory app.main:create_app --reload
+# → http://localhost:8000
+```
+
+## Deployment (Linux, nginx)
+
+1. Copy the repo to `/opt/backup-dashboard`, create a venv at `/opt/backup-dashboard/venv`, and run `pip install -r backend/requirements.txt`.
+2. Copy `deploy/backup-dashboard.env` to `/etc/backup-dashboard/backup-dashboard.env`. Both the service and `manage.py` read their settings from it.
+3. Create a `backupdash` system user, then install `deploy/backup-dashboard-api.service` into `/etc/systemd/system/` and enable it. The database is created on first start.
+4. Copy `public/` to `/var/www/backup-dashboard/public`, install `deploy/nginx.conf`, get a certificate with certbot, and create users with `htpasswd -B`.
+5. Run `manage.py` as the service user. It finds the database through the env file:
+   ```bash
+   cd /opt/backup-dashboard/backend
+   sudo -u backupdash /opt/backup-dashboard/venv/bin/python manage.py create-key veeam-acme
+   ```
+   It prints the database path it's using and won't create a new database unless you pass `--create`.
+
+Back up the SQLite file with `sqlite3 backup-dashboard.db ".backup copy.db"`. Don't use a plain `cp`
+while the service is running.
