From the developer:
SnaPatch connects and interacts with Microsoft's System Centre Configuration Manager SCCM , VMware's ESX and now also Microsoft's HyperV. By bridging all of these platforms it allows us to remove the inherent risk associated with patching and updating servers. This is achieved by automatically taking snapshots of the virtual server prior to deploying any patches.
