Abstract

See full text

When an access metric regarding an encoded data object exceeds an access threshold, a method begins by a processing module of a dispersed storage network (DSN) retrieving encoded data slices of a first plurality of sets of encoded data slices and recovering the data object utilizing first dispersed storage error encoding parameters. The method continues with the processing module re-encoding the recovered data object using second dispersed storage error encoding parameters to produce a re-encoded data object, where the re-encoded data object includes a second plurality of sets of encoded data slices. The method continues with the processing module outputting the second plurality of sets of encoded data slices to storage units of the DSN for storage therein and sending a message to retrieving devices of the DSN, where the message indicates use of the second plurality of sets of encoded data slices for the data object.
