A data de-duplication method begins by a processing module receiving a plurality of data storage requests from a plurality of requesting devices wherein a data storage request includes the data and a requester identifier (ID). The method continues with the processing module obtaining a data identifier (ID) for the data. For each of the plurality of data storage requests, the method continues with the processing module producing a requester storage record, dispersed storage error encoding the requester storage record to produce a set of encoded requester storage record slices, and sending the set of encoded requester storage record slices to a dispersed storage network (DSN) memory for storage therein. The method continues with the processing module dispersed storage error encoding at least a portion of the data to produce a set of encoded data slices and sending the set of encoded data slices to the DSN memory for storage therein.
