Abstract
Described herein, system that facilitates recovery of an object segment in a geographically distributed storage environment. According to an embodiment, a system can comprise receiving a read request to read an object segment from a first data chunk stored in a geographically diverse data storage system, wherein the first data chunk is inaccessible, executing a GEO recovery process in response to determining that the first data chunk is inaccessible, wherein the GEO recovery process comprises accessing a first slice of data from a second data chunk stored in the geographically diverse data storage system, accessing a second slice of data from a third data chunk stored in the geographically diverse data storage system, and applying an XOR operation to the first slice of data and the second slice of data to determine a third slice of data, and extracting the object segment from the third slice of data.
