      • The restoration takes about one minute. Then, the object is in the restored state.
      • By default, the object remains in the restored state for one day. You can use ossutil or SDKs to prolong this period to a maximum of seven days. When this period expires, the object returns to the frozen state. For more information, see restore and Restore objects.
