Changes such as write operations on a replication source comprising a hierarchically-indexed file system and associated data store are tracked and aggregated over a point-in-time image replication interval and communicated to a replication target. The replication target receives the changes, conducts operations to make the changes on a target volume or portion thereof, and conducts a point-in-time image replication operation to synchronize the replication target with the replication source. In the present invention the advantages of replication techniques developed for log-structured file systems are provided to systems with conventional hierarchical file systems. The invention also facilitates maintaining point-in-time retrievable images of a volume or portion thereof on a target volume while reducing the bandwidth and processing burden associated with replication.
