For file replication only, to replicate large files more efficiently, the server also supports incremental block replication. With incremental block replication, only the changes in files are replicated and not the whole file, thus reducing the amount of data replicated and the overall replication time.

Note: Block-level replication copies the entire file if the file has multiple hard links.
Note: The Block-Level Replication feature is automatically enabled if the Replication license is present.
