I'm virtualising our entire system to VM's. The plan is i'll be setting up our existing 'VMWARE Server 2' Servers to ESXi 4.1. We'll have 3 and that will allow us to only need to buy the Vmware Essentials Kit.
Main thing, Backups. What is the best way to backup these. I found something online called 'esXpress'. It seemed puuurfeect. But then I encountered some errors and apparently it doesn't support ESXi.
