## Towbar manifest

```yaml title=".towbar/datastores/aws-s3-destination.datastore.yml" theme={"system"}
id: aws-s3-destination
name: AWS S3
type: postgres
container:
  network: application
  networkAlias: aws-s3-destination
  resources:
    cpus: 1
    memory: 1g
secrets:
  runtime:
    - POSTGRES_USER
    - POSTGRES_DB
    - POSTGRES_PASSWORD
environments:
  production:
    server: 192.0.2.10
backup:
  integration: aws

```

## Configure

1. Register and prepare the example server or servers, connect the repository, and map `production` to the branch containing these files.
2. Save each Datastore credential value under **Datastore → Settings → Secrets**, deploy it first, and verify engine readiness before starting a dependent Service.
3. Enable the selected backup integration and configure its runtime storage credentials and destination before creating a recovery point. A manifest policy alone does not provide storage access.
4. Sync the repository, inspect the resolved configuration, deploy manually, and perform the verification below before enabling automation.

## Verify

The runtime identity can write, read, and delete under the intended location.
