The subject of this paper is dedicated to questions on archiving and preservation of born digital media art. It investigates to what extent virtualisation is suitable as an increasingly accepted method for conserving especially computerand internet-based media artworks. Summarising interim conclusions of AktiveArchive [1], the empirical basis is formed by case studies. The handling system failure examines possible preservation approaches. As the research is embedded in a broader context it devotes conclusions on a more theoretical level. Considerations on sustainability are discussed implicit. Actionoriented electronic works of cultural value provide the center of our research. The focus on media art projects accounts for an arttechnological approach.
