Cause

NetWorker markerer klonet forkert saveset som gyldig, selv når kilden saveset er beskadiget, og klonhandlingen mislykkes. Denne funktionsmåde skyldes en defekt i klonvalideringslogikken.

Resolution

En rettelse til dette problem findes i følgende NetWorker-versioner:

  • 19.9.0.5
  • 19.10.0.2
  • Alle versioner over 19.11.x

Opgrader til en af ovenstående versioner for at sikre, at den er beskadiget savesets er korrekt markeret som ugyldige under kloning.
