Abstract

See full text

A computing device includes an interface configured to interface and communicate with a dispersed storage network (DSN), a memory that stores operational instructions, and a processing module operably coupled to the interface and memory such that the processing module, when operable within the computing device based on the operational instructions, is configured to perform various operations. The computing device receives a data access request for a data object and determines a first revision number of a corresponding set of EDSs stored among first SU(s) and a second revision number of a corresponding trimmed copy of the set of EDSs stored among second SU(s). When the second revision number compares favorably to the first revision number, the computing device issues the data access request to the first SU(s) and/or the second SU(s) and issues the data access request for the data object to only the first SU(s) when it doesn't.
