  # "default" is a special group name: Longhorn auto-applies it to every
  # volume that has NO recurring-job label at all - i.e. opt-out. To
  # exclude a specific volume, give it any other (job-less) group label,
  # e.g.:
  #   recurring-job-group.longhorn.io/no-backup: enabled
  # (having *any* recurring-job label disqualifies it from "default" -
  # there's no dedicated "disabled" flag, this placeholder-group is the
  # documented workaround)
