Which of the following is NOT a step in the installation of the HTML5 gateway?

Running a database backup is not a step in the installation of the HTML5 gateway. The installation process typically focuses on setting up the necessary components and services that enable the gateway to function correctly. This includes installing the guacamole daemon, which facilitates the remote access capabilities, ensuring that all required libraries are in place for the system to operate efficiently, and installing the HTML WebApp, which provides the user interface for accessing services.

In contrast, taking a database backup, while a critical maintenance task, is not part of the initial installation process. It may be relevant to data management and disaster recovery practices but does not directly pertain to the steps required to set up the HTML5 gateway itself.
