A device implementing a system for object placement includes at least one processor configured to identify an object stored on two of a plurality of storage devices, and to determine a pairing value for each pair of the plurality of storage devices, the pairing value corresponding to a number of stored objects common to the pair. The at least one processor is further configured to select, based on the determined pairing values, two storage devices having a lowest pairing value relative to the determined pairing values, and to move the object to each of the two selected storage devices.

Distributed redundant storage system

The embodiments set forth a technique that enables the storage of data at a first data storage device. The technique includes, at the first data storage device, dividing the data to produce a first and second portion of the data, in which the first and second portions are associated with a computed exclusive or ('XOR') value. Also, the technique includes deleting the second portion stored at the first data storage device, based at least in part on whether the computed XOR value is established. Also, the technique includes receiving a first replicated metadata, in which the first replicated metadata indicates a location of the second portion stored at the second data storage device. Furthermore, the technique includes communicating either the first portion or the second portion, to a remote computing device, based at least in part on the first replicated metadata.
