If you want to take a copy of the data you collect, you are advised to plug an external hard-drive into the DataDispenser computer during your session. This will collect your data as you go.

The DataDispenser is a small 'headless' (i.e. No monitor or keyboard attached) Linux computer to which USB hard-drives can be connected. It is operated via a web-interface which will enable the streaming of your data directly to a portable disk that you can take with you when you leave.

Open

1. Plug your external hard drive into the DataDispenser and note the port name.

2. Log in to any computer, and in a PRIVATE internet browser, enter following url:

3. Click Define a new Clone (login with your FedID if prompted to do so).
   Each 'Clone' is a unique process for copying the data into the area you specify.
