ABSTRACT:
Various methods and systems for synchronizing replicas using a single change map are disclosed. One method involves detecting a write to a first region of a volume, while synchronization of the volume with a replica volume is ongoing. If the first region is unsynchronized with respect to a corresponding region of the replica volume, replication of the write is inhibited. Otherwise, the write is replicated. Writes for which replication is inhibited will be applied to the replica volume at a later time as part of the ongoing synchronization.
