The rise of ubiquitous computing has created a need for wide-area
durable storage. We propose a model and interface for such an archival
system, that stores data in a durable, verifiable, available, and self-maintainable
manner. We argue that such a
system can be created by using novel techniques of erasure codes,
secure hashing, and decentralized wide-area location infrastructures to
distribute fragments across the wide-area on an arbitrary set of servers.
This model allows files to remain available even as servers fail.
Finally, we implement Silverback, a prototype archival system using the
model that we developed, and measure its performance.
