Abstract
Selectively distributing fragments of a data protection set in a geographically diverse data storage system is disclosed. The data protection set can comprise fewer fragments than there are zones comprising the geographically diverse data storage system, which can result in some zones not storing a fragment of the data protection set. Control over distribution of fragments of different data protection sets in the geographically diverse data storage system can mitigate or avoid unbalanced storage of the protection sets. The distribution can be controlled in accordance with a protection set distribution scheme (PSDS). A first PSDS can generate coding fragments from randomly select data fragments of all zones. A second PSDS can generate coding fragments from determined unique zone combinations. A third PSDS can generate coding fragments based on affinity values from an affinity matrix. In embodiments, threshold values or rules can be employed to force generation of a protection set regardless of an applied PSDS where the PSDS excessively retards generation of sufficient protections sets.
