1. A dispersed storage device for use within a dispersed storage network, comprising: an interface; and a processing module operable to: slice a data segment of a data object into data slices, a number of the data slices corresponding to a number of pillars for storing the data object, each of the pillars corresponding to a particular data slice of each data segment of each data object written to a vault, the vault being associated with at least one user; create a slice name for each of the data slices, the slice name including: routing information containing: a vault identifier that identifies the vault associated with the data object; and a slice index based on the vault identifier and a pillar identifier that identifies a pillar associated with the data slice; and a source data name containing an identifier of the data object; and output, via the interface, a data slice of the data slices and the respective slice name to a corresponding storage unit for storage therein.
