  abstract = {This paper presents the design and implementation of a mobile
  storage system called a PersonalRAID. PersonalRAID manages a number of
  disconnected storage devices. At the heart of a PersonalRAID system is a
  mobile storage device that transparently propagates data to ensure eventual
  consistency. Using this mobile device, a PersonalRAID provides the
  abstraction of a single coherent storage name space that is available
  everywhere, and it ensures reliability by maintaining data redundancy on a
  number of storage devices. One central aspect of the PersonalRAID design is
  that the entire storage system consists solely of a collection of storage
  logs; the log-structured design not only provides an efficient means for
  update propagation, but also allows efficient direct I/O accesses to the logs
  without incurring unnecessary log replay delays. The PersonalRAID prototype
  demonstrates that the system provides the desired transparency and
  reliability functionalities without imposing any serious performance penalty
  on a mobile storage user.}
