I think the behavior of deepcopy in #7112 is correct. I you really want to prevent the ancillary_variables attrs to be deep-copied as well, you can try to add it to the memo dict in deepcopy, e.g.: python memo = {id(da.attrs["ancillary_variables"]): da.attrs["ancillary_variables"]} da_new = deepcopy(da, memo) (untested!)
