The aim of this essay is to draw restorers' and theorists' attention to the phenomena that exist in virtual space. This should be associated with a very specific type of restoration that unfortunately does not yet exist in practice or exists in its amateur form. This means research related to the restoration of net art (net.art, internet art). It is likely that the significance of this art will increase only at the beginning of the next millennium. A question will arise how to save things that have already lost their form.
The significance of net art security is viewed through the eyes of a restorer in this essay. Based on the realisation that virtual phenomena are intangible, attempts have been made to clarify technical possibilities to preserve this art. Because of this, there have been no efforts to identify the things that should be preserved and things that should be simply rejected.
