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.

Claim (Index 7):
The system of  claim 1 , wherein:\n the number of data zones is four; an initial state of the distributed storage construct prior to performing the operations is:\n the first data zone comprises data chunk A1, data chunk A2, data chunk A3, and the second combined data chunk, wherein the first data chunk is the data chunk A1, and wherein the second combined data chunk is a first XOR combination of data chunk B3, data chunk D2, and data chunk C1; \n the second data zone comprises data chunk B1, data chunk B2, the data chunk B3, and the first combined data chunk, wherein the second data chunk is the data chunk B3, and wherein the first combined data chunk is a second XOR combination of the data chunk A1, data chunk C2, and data chunk D3; \n the third data zone comprises the data chunk C1, the data chunk C2, data chunk C3, and a third combined data chunk that is a third XOR combination of the data chunk A3, the data chunk B2, and data chunk D1; and \n a fourth data zone comprises the data chunk D1, the data chunk D2, the data chunk D3, and a fourth combined data chunk that is a fourth XOR combination of the data chunk A2, the data chunk B1, and the data chunk C3; and \n a resulting state of the distributed storage construct after performing the operations is:\n the second data zone comprises the data chunk B1, the data chunk B2, the data chunk B3, a primary copy of the data chunk A1, a secondary copy of the data chunk A3, the modified first combined data chunk that is a fifth XOR combination of the data chunk C2, and the data chunk D3, and the modified second combined data chunk that is a sixth XOR combination of the data chunk D2 and the data chunk C1; \n the third data zone comprises the data chunk C1, the data chunk C2, the data chunk C3, a primary copy of the data chunk A3, a secondary copy of the data chunk A2, a secondary copy of the data chunk B3, and a modified third combined data chunk that is a seventh XOR combination of the data chunk B2 and the data chunk D1; and \n the fourth data zone comprises the data chunk D1, the data chunk D2, the data chunk D3, a primary copy of the data chunk A2, a secondary copy of the data chunk A1, and a modified fourth combined data chunk that is an eighth XOR combination of the data chunk B1 and the data chunk C3.
