David Szpunar on 23 Feb 11"So ... we can effectively back up the configuration of our ESXi hosts (- 10 minute changes worst case) simply by backing up the state tardisk, then if the worst happens we can restore this and have our ESXi host with complete configuration restored in a matter of minute. Luckily PowerCLI makes this very easy for us, the below script can be run as a scheduled task and will backup the state tardisk as often as the scheduled task is run."
