Zusammenfassung:One or more techniques and/or computing devices are provided for directory level incremental replication. For example, a first storage controller may evaluate a base snapshot and an incremental snapshot of a source subdirectory to generate a set of operations that can be used by a second storage controller for reconstructing a mirror of the source subdirectory as reflected by the incremental snapshot. Accordingly, the first storage controller may send the set of operations and/or source data to the second storage controller for constructing a destination directory structure mirroring the source subdirectory. In this way, replication may be achieved at an arbitrary level of granularity, such as to replicate a particular subdirectory of a volume.
