Keine Repository-Dateien, Tests oder Einstiegspunkte sind identifiziert. Beginne damit, die Wiederherstellung von WideWorldImporters auf SQL Server 2016 zu reproduzieren, und untersuche das Server-Fehlerprotokoll auf den Wiederherstellungsfehler hinter Fehler 3414. Als erledigt gilt die Aufgabe, wenn die Beispieldatenbank ohne den Wiederherstellungsfehler erfolgreich wiederhergestellt wird.
