Use the files you exported when configuring vSphere Trust Authority as your Trust Authority backup. You can use these files to restore a Trust Authority deployment. Keep these configuration files confidential and transport them securely.
Most vSphere Trust Authority configuration and state information is stored on the ESXi hosts in the ConfigStore database. The vCenter Server Management Interface that you use to back up a vCenter Server instance does not back up the configuration information for vSphere Trust Authority. If you save and securely store the configuration files that you exported when setting up your vSphere Trust Authority environment, then you have the necessary information to restore a vSphere Trust Authority configuration. See Collect Information About ESXi Hosts and vCenter Server to Be Trusted if you must generate this information.
