# POST /api/backup

Proactively refreshes all cache entries by iterating over all projects and their integrations, calling each fetcher with `forceRefresh: true`.

## Authentication

Requires a Bearer token matching the `BACKUP_SECRET` environment variable.

```
Authorization: Bearer <BACKUP_SECRET>
```

## Request body

None.

## Response

```json theme={null}
{
  "refreshed": 42,
  "failed": 1,
  "duration": "2m 15s",
  "errors": [
    {
      "project": "goshuin-atlas",
      "integration": "sentry",
      "error": "Rate limited"
    }
  ]
}
```

## Rate limit awareness

The backup endpoint applies delays between service calls to avoid hitting rate limits:

| Service           | Delay between calls |
| ----------------- | ------------------- |
| RevenueCat        | 15 seconds          |
| App Store Connect | 2 seconds           |
| All others        | 500ms               |

See [Backup System](/developer-guide/backup-system) for details on running this as a cron job.
