Towards reliable backup on the net by combining markets, swarming and erasure codes

We present CyberStash, a blueprint for a wide-area storage network that is both more reliable and more scalable than traditional storage methods. Our principal goal is to make advanced backup technology accessible to regular consumers. The chosen architecture is therefore simple to use and maintain. Because of its global span CyberStash can serve not only as a backup tool, but as a cornerstone enabling the vision of pervasive computing [1], [2]. We identify requirements, present an architecture and analytically find a lower bound on reliability that surpasses traditional approaches.
