Abstract
One embodiment is related to a method for implementing a demoted chunk, comprising: replicating a first chunk from a first zone of a cloud storage system to a third zone of the cloud storage system; replicating a second chunk from a second zone of the cloud storage system to the third zone; creating an exclusive or (XOR) chunk at the third zone based at least in part on the replicated first chunk and the replicated second chunk; and marking the replicated first chunk and the replicated second chunk as demoted first chunk and demoted second chunk, respectively, at the third zone.
