A dispersed storage network includes a dispersed storage device to store data. The dispersed storage device includes a processing module operable to slice a data segment of a data object into data slices, in which the number of data slices corresponds to a number of pillars for storing the data object. The processing module further creates a slice name for each of the data slices. The slice name includes routing information containing a vault identifier that identifies at least one user of 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. In addition, the slice name includes a source data name containing an identifier of the data object.
