Abstract
Multiple copy sets of data are maintained on one or more storage devices. Each copy set includes at least some of the same data units as other sets. Different sets optionally have data units stored in different orders on the storage device(s). A particular one of the sets of data is selected as the set to be accessed in response to detecting a particular scenario.
