Abstract
A system and method for fixing data inconsistency between an original dataset stored on a source storage server and a mirror of the original dataset stored on a destination storage server is provided. The method determines whether the mirror is consistent with the original dataset by comparing metadata describing the original dataset with metadata describing the mirror. If the mirror is inconsistent with the original dataset, corresponding block(s) of the original dataset is/are requested and received from the source storage server. The mirror is then fixed according to the received block(s).
