list method
Lists Backup in a given project.
Request parameters:
parent - Required. The domain resource name using the form:
projects/{project_id}/locations/global/domains/{domain_name}
Value must have pattern
^projects/\[^/\]+/locations/global/domains/\[^/\]+$.
filter - Optional. Filter specifying constraints of a list operation.
orderBy - Optional. Specifies the ordering of results following syntax
at https://cloud.google.com/apis/design/design_patterns#sorting_order.
pageSize - Optional. The maximum number of items to return. If not
specified, a default value of 1000 will be used by the service. Regardless
of the page_size value, the response may include a partial list and a
caller should only rely on response's next_page_token to determine if
there are more instances left to be queried.
pageToken - Optional. The next_page_token value returned from a
previous List request, if any.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a ListBackupsResponse.
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.
