One embodiment is related to a method for remote replication recovery, comprising: determining that a damaged data chunk at a first zone of a cloud storage system is not recoverable locally; determining one or more data fragments of the damaged data chunk that are to be recovered with remote replication recovery based on data stored at a second zone and at a third zone of the cloud storage system, wherein the damaged data chunk comprises a plurality of data fragments; recovering the one or more data fragments of the damaged data chunk with remote replication recovery based on the data stored at the second zone and at the third zone of the cloud storage system; and repairing the damaged data chunk with the recovered data fragments at the first zone.
