  1. Logon to your Cacti server.

  2. For this example, let's assume you have it copied into the /backup directory.

  3. Change to the root directory:

    cd /
    
  4. Extract the contents of the backup:

    tar –xzvpf /backup/cacti_files_20101004.tgz
    
  5. You will see the contents of the archive being displayed on the screen during the extraction process, as shown in the following screenshot:

You will need to restart all relevant services afterwards, or reboot the system to make all the changes to the configuration files active.
