Hallo,

bei einer Prüfung auf einem EX2019 fiel mir auf, dass in den Exchange Verzeichnissen massenhaft *.BAK Dateien vorliegen. Vermutlich von früheren ServicePacks/Patches etc.

Die Anzahl und Menge erscheint mir nicht mehr ganz trivial:

Anzahl der angezeigten Dateien:
696 Datei(en), 5.479.392.904 Bytes

Beispielhaft:

usw.

Was mache ich jetzt mit den BAKs? Einfach mal alles durchweg weglöschen?

Was ist der beste Weg?
