Abstract
Embodiments are directed to a file system engine that provides a file system with parent objects associated with child objects. The file system engine provides a replication snapshot associated with an epoch of the file system such that each child object modified during the epoch and each associated parent object is associated with the replication snapshot. A root object of a portion of the file system included in the replication snapshot may be provided. A replication engine may traverse the portion of file system starting from the root object such that the parent objects that are not associated with the replication snapshot are omitted from the traversal. The replication engine may determine replication objects based on the traversal such that each replication object was modified during the epoch. Then the replication engine may execute a replication job that copies replication objects to a target file system.
