Offene Snapshots in SCVMM reporten

Mal wieder ein Klassiker… offene Snapshots.

Hier wird ein Report erstellt und per Mail geschickt, der alle offenen Snapshot der Hyper-V Umgebung (mittels SCVMM) ermittelt. Es gibt eine Besonderheit: Manche Snapshots dürfen da sein. Diese sind dann mit “persistent” in der Snapshot Beschreibung gekennzeichnet.
