You can back up a presentation network on a memory stick, CD, DVD, external hard drive, or another computer. In fact, you can present directly from any of these storage devices and all your links will work perfectly, assuming you set up your network properly in the first place. We regularly back up our network in several ways before a training or speaking event, just in case there is an equipment failure and we have to use someone else’s computer. The Aspire training network has hundreds of thousands of links and we regularly transfer it between computers and storage devices without incident.
