Research fuelled by the use of data from social networks sometimes involves gathering an impressive amount of data. The processing of these data usually takes place in remote locations in the cloud and, to be able to reach them, it is necessary to use shared networks, public networks, etc. Under such circumstances, it is usually extremely hard to make all data available for the data subjects. On the other hand, it is worth noting that the integrity of the data might be compromised by the way in which they are shared and stored. It might happen that one of the processors or joint controllers deletes or damages the data at some point. In order to prevent such scenarios, backup copies are highly recommended. Their creation should be foreseen from the first stages of the research.
