Seeding replication is disclosed. One or more but not all files stored on a deduplicated storage system are selected to be replicated. One or more segments referred to by the selected one or more but not all files are determined. A data structure is created that is used to indicate that at least the one or more segments are to be replicated. In the event that an indication based at least in part on the data structure indicates that a candidate segment stored on the deduplicating storage system is to be replicated, the candidate segment is replicated.
