A free, open source program http://www.httrack.com/page/2/en/index.html will allow you to create an offline version of your Freshdesk site. This can be handy for reference if data on the live site is deleted unintentionally, and can be very useful when an Internet connection is not available. For most sites it should take less than an hour to complete the copy. The data can then be copied to a CD or DVD for a portable version of Freshdesk
The program is very easy to use. Although it has many configurable parameters, all you really need supply is your url plus login and password.
