Backup von Gastsystemen auf VMware ESX
Um beim ESX Server die Gastbetriebssysteme ohne einen suspend hot backup sichern zu können, hat Massimiliano Daneri das vmbk.pl Skript entwickelt. Das Skript verwendet die Funktionen des ESX-Servers um eine REDO-LOG Disk zu erstellen, so dass ein backup der gesamten Disk mittels des vmfstools Befehls ermöglicht wird.

Für die Installation benötigt man rh7 Mime::Lite rpm,local copy und
ESX Backup Skript vmbk.pl Homepage local copy (68K)
Konfiguration
Die Konfiguration wird sowohl über die .vmx-Dateien als auch die vmbk.conf Datei gesteuert.
