Backing up VMware ESXi VMs with ghettoVCB

Backups are important – and VMs should be no exception to that. VMware does have their own official backup solution (vSphere Data Protection), however if you’re running on the free version of ESXi or want something a little bit less resource-heavy, ghettoVCB is a good, and free, alternative – perfect for a home lab!
