Abstract
Scaling-in of a geographically diverse data storage system is disclosed. Data chunks stored in storage devices of different zones can be convolved to conserve memory. The zone storage system can be a geographically diverse storage system. Removing a zone from the geographically diverse data storage system can risk data loss without adequate replication of data from the zone to be removed. The zone to be removed can be placed in a 'read-only' state. Data chunks form the zone to be removed can be duplicated at other zones of the geographically diverse data storage system. A data chunk comprising convolved representations of data is duplicated to a zone in a manner that results in loss of geographical diversity, a corresponding chunk can be duplicated at another zone to restore geographical diversity. Validation of data can be performed prior to removal of a zone in a scaling-in event.
