Abstract: Data convolution for geographically diverse storage is disclosed, wherein the data convolution is based on a valency metric, determination, parameter, etc. Valency can be correlated to a data object and can be inherited by a chunk comprising the data object. Valency can indicate permitted levels of convolution for a chunk. A chunk resulting from convolving at least two other contributing/participating chunks can be determined to have a valency that can be less than either of the two contributing/participating chunks. A chunk with a zero valence can be restricted from contributing to a convolution. Where the at least two other chunks both have infinite valency, the resulting convolved chunk can also have infinite valency. A chunk resulting from convolving participating chunks having mixed valency values can be reconvolved. Valency can enable orchestrating convolution of chunks, for example, to conserving storage space, mitigate computing resource consumption, etc.
