A method begins by a dispersed storage (DS) processing module generating preliminary dispersed storage network (DSN) storage information for data to be stored in a DSN. The method continues with the DS processing module accessing DSN storage information regarding other data stored in the DSN and comparing the preliminary DSN storage information for the data with the DSN storage information regarding the other data. When at least a portion of the data has compatible preliminary DSN storage information with DSN storage information of at least a portion of the other data, the method continues with the DS processing module generating DSN storage information for remaining portions of the data to produce remaining portions DSN storage information and generating DSN storage information for the data based on the DSN storage information of the at least the portion of the other data and the remaining portions DSN storage information.
