VMWare ESXi is an installable/embeddable virtualization platform based around the ESXi Hypervisor.

VMWare ESXi is a type 1 hypervisor based virtualization platform that installs on bare hardware (no host OS required) that allows running multiple guest virtual machines simultaneously.

ESXi is available freely with basic single-server functionality, but more advanced functionality requires licensing commercial versions of VMWare vSphere (formerly known as VMWare Infrastructure prior to version 4.0). ESXi lacks the linux-based service console included with VMWare ESX, further reducing install footprint and attack surface.

Why don't people just use rsync to back up vmware guests?

If I am running a modern vmware ESXi system, I can drop in a statically linked rsync binary and rsync files to any destination over SSH. I'm trying to understand why most (all ?) backup of vmware guests is not done this way. If the VM is running,…
