## Example

```ts

// The values are placeholders you should change.
import { aws_backup as backup } from 'aws-cdk-lib';

declare const indexActionResourceType: backup.IndexActionResourceType;
const backupPlanIndexActionProps: backup.BackupPlanIndexActionProps = {
  resourceTypes: [indexActionResourceType],
};
```

## Properties

- `resourceTypes`: [IndexActionResourceType](/cdk/api/v2/docs/aws-cdk-lib.aws_backup.IndexActionResourceType.html)[] (required) — Specifies the resource types to include in the index action.

  A backup index is only created when this is set, so at least one resource
  type must be provided.
