DISPERSED STORAGE NETWORK WITH DATA SEGMENT BACKUP AND METHODS FOR USE THEREWITH

摘要

A method begins with a processing module selecting one of a plurality of dispersed storage (DS) processing modules for facilitating access to a dispersed storage network (DSN) memory. The method continues with the processing module sending a DSN memory access request to the one of the plurality of DS processing modules. The method continues with the processing module selecting another one of the plurality of DS processing modules when no response is received within a given time frame or when the response to the access request does not include an access indication. The method continues with the processing module sending the DSN memory access request to the another one of the plurality of DS processing modules.

1. A method for execution by one or more processing modules of one or more computing devices of a dispersed storage network (DSN), the method comprises:
providing a data segment; retrieving a plurality of first slices, corresponding to a previous revision of the data segment, from the distributed storage network; recreating the previous revision of the data segment from the plurality of first slices corresponding to the previous revision of the data segment; determining if the previous revision of the data segment compares unfavorably to the data segment; and storing the data segment in the DSN when determined that the previous version of the data segment compares unfavorably to the data segment.
