The TLS Configuration utility performs a backup each time the script modifies vCenter Server, Platform Services Controller, or vSphere Update Manager on the vCenter Server Appliance. If you need a backup to a specific directory, you can perform a manual backup.

Backup of the ESXi configuration is not supported.

For vCenter Server or Platform Services Controller, the default directory differs for Windows and the appliance.
OS Backup Directory
Windows c:\users\current_user\appdata\local\temp\yearmonthdayTtime
Linux /tmp/yearmonthdayTtime

Procedure

  1. Change directory to vSphereTlsReconfigurator, and then to the VcTlsReconfigurator subdirectory.
    OS Command
    Windows 
    C:\Program Files\VMware\CIS\vSphereTlsReconfigurator\
cd VcTlsReconfigurator
    Linux 
    cd /usr/lib/vmware-vSphereTlsReconfigurator/
cd VcTlsReconfigurator
  2. Run the following command to make a backup to a specific directory.
    OS Command
    Windows 
    directory_path\VcTlsReconfigurator> reconfigureVc backup -d backup_directory_path
    Linux 
    directory_path/VcTlsReconfigurator> ./reconfigureVc backup -d backup_directory_path
  3. Verify that the backup was successful.
    A successful backup looks similar to the following example. The order of services displayed might be different each time you run the reconfigureVc backup command, due to the way the command runs. 
    vCenter Transport Layer Security reconfigurator, version=6.5.0, build=4635484
