Create a System Image
Once you have set up your appliance and configured the HOTPin application,
creating a snapshot will provide an option to help remediate issues that may
result from future system updates or changes.
You have two options to access the system image functionality:
• The web UI System Imaging feature (Maintenance|System Imaging).
• The front panel display Last Good Version (LGV) feature (access through
the Jog Dial).
In each option the image is created in the recovery system process where the
main operating system is not running. Thus system can be restored to the initial
configuration even if the operating system performance or functionality has been
affected. Neither option above is recommended in lieu of a normal backup
procedure.
The System Imaging option requires the use of a web browser, but can run
when the operating system is loaded (online), or after a restart before the
appliance boots into the operating system (offline). Online, or real-time, images
use more disk space than offline imaging, but they don’t interrupt the services
your appliance provides.
The LGV feature is an offline tool and requires that the system be rebooted to
access it. But it can be run from the front panel and is convenient if you don’t
have a monitor and keyboard attached to the appliance.
