Abstract
An infrastructure on a file server registers one or more replication modules to support file replication across a plurality of file servers. Each replication module can support file replication for any number of volumes on the file server, but each volume can be replicated by at most one replication module. The replication modules register with the replication module by identifying themselves to the replication infrastructure, identifying those activities the replication modules wish to be notified about, and identifying those volumes each replication module will support. The replication infrastructure tracks each volume. When a watched activity occurs, the replication infrastructure notifies the supporting replication module. Finally, when the replication infrastructure receives an update from the replication module, the replication infrastructure performs the update to the supported volume.
