Described is an information dispersal system in which original data to be
stored is separated into a number of data "slices" in such a manner that
the data in each subset is less usable or less recognizable or completely
unusable or completely unrecognizable by itself except when combined with
some or all of the other data subsets. These data subsets are stored on
separate storage devices as a way of increasing privacy and security. A
metadata management system stores and indexes user files across all of
the storage nodes. The metadata management system stores metadata for
dispersed data where: the dispersed data is in several pieces; and the
metadata is in a separate dataspace from the dispersed data.
