You can back up and restore the appliance from the appliance management interface.
Backup and restore operations are available in the appliance management interface except when restricted by a cloud service provider. You first use the appliance management interface to generate a configuration file and then use that file to restore to a healthy system.
The HCX service appliances, which include HCX-IX and HCX-NE, do not require individual backups. A restored HCX Manager reconnects to existing service appliances that were created within the backup time frame. If the service appliances are no longer functional, the HCX Manager deploys new appliance virtual machines based on the backed-up configuration.
