copy method

Future<Operation> copy(
  1. CopyBackupRequest request,
  2. String parent, {
  3. String? $fields,
})

Starts copying a Cloud Spanner Backup.

The returned backup long-running operation will have a name of the format projects//instances//backups//operations/ and can be used to track copying of the backup. The operation is associated with the destination backup. The metadata field type is CopyBackupMetadata. The response field type is Backup, if successful. Cancelling the returned operation will stop the copying and delete the destination backup. Concurrent CopyBackup requests can run on the same source backup.

request - The metadata request object.

Request parameters:

parent - Required. The name of the destination instance that will contain the backup copy. Values are of the form: projects//instances/. Value must have pattern ^projects/\[^/\]+/instances/\[^/\]+$.

$fields - Selector specifying which fields to include in a partial response.

Completes with a Operation.

Completes with a commons.ApiRequestError if the API endpoint returned an error.

If the used http.Client completes with an error when making a REST call, this method will complete with the same error.

Implementation

async.Future<Operation> copy(
  CopyBackupRequest request,
  core.String parent, {
  core.String? $fields,
}) async {
  final body_ = convert.json.encode(request);
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };

  final url_ = 'v1/' + core.Uri.encodeFull('$parent') + '/backups:copy';

  final response_ = await _requester.request(
    url_,
    'POST',
    body: body_,
    queryParams: queryParams_,
  );
  return Operation.fromJson(response_ as core.Map<core.String, core.dynamic>);
