((a)) When the record of any case or matter in any court of the United States to which the United States is a party, is lost or destroyed, a certified copy of any official paper of a United States attorney, United States marshal or clerk or other certifying or recording officer of any such court, made pursuant to law, on file in any department or agency of the United States and relating to such case or matter, shall, on being filed in the court to which it relates, have the same effect as an original paper filed in such court. If the copy so filed discloses the date and amount of a judgment or decree and the names of the parties thereto, the court may enforce the judgment or decree as though the original record had not been lost or destroyed.

((b)) Whenever the United States is interested in any lost or destroyed records or files of a court of the United States, the clerk of such court and the United States attorney for the district shall take the steps necessary to restore such records or files, under the direction of the judges of such court.
