Installing and configuring VMware vSphere Data Protection (VDP)

You might think that your machines are safe and that you have nothing to worry about once you virtualize your infrastructure, but that’s not true. Virtual machines need backups, the same as physical machines do. This is not necessarily because of a host crash or any other hardware problem,
