Abstract: A method begins by storage units of a first pool of storage units of a plurality of pools detecting a change to a weighting factor of a pool of storage units and calculating an updated plurality of storage pool scores for a respective encoded data slice of a set of encoded data slices that is stored by a respective storage unit of the first pool of storage units. The method continues with each of the storage units of the first pool of storage units identifying one pool of storage units having a desired storage pool score based on the updated plurality of storage pool scores. When the one pool of storage units is not the first pool of storage units, each of the storage units of the first pool of storage units transfers the respective encoded data slice to a corresponding storage unit of the one pool of storage units.

Abstract: A method begins by a dispersed storage (DS) processing module receiving data for storage and generating a dispersed storage network (DSN) source name for the data. The method continues with the DS processing module determining whether substantially identical data to the data has been previously stored in memory of the DSN. When the substantially identical data has been previously stored in the memory of the DSN, the method continues with the DS processing module generating an object linking file that links the data to the substantially identical data, dispersed storage error encoding the object linking file to produce a set of encoded link file slices, and outputting the set of encoded link file slices for storage in the memory of the DSN.

Abstract: A method begins by a dispersed storage (DS) processing module selecting a data segment and verifying integrity values of encoded data slices generated by encoding the data segment. When integrity values of a decode threshold number of encoded data slices are affirmatively verified, the method continues with the DS processing module verifying an integrity value of the data segment. When the integrity value of the data segment is affirmatively verified, the method continues with the DS processing module generating a new set of encoded data slices. The method continues with the DS processing module verifying concurrency of the set of encoded data slices with the new set of encoded data slices and for each encoded data slice having a negative concurrency verification, flagging the encoded data slice as being potentially compromised.
