VMware NSX for vSphere 6.x does not support backup and restore functions on the controller as the NSX Manager stores all hard state. These buttons and commands are not supported on NSX for vSphere:
- copy file command
- show file command
- restore control-cluster snapshot command
- Download controller snapshot button
Note: VMware NSX for Multi-Hypervisor 4.x does support these options as the controller persists all configuration state.
