Abstract
A data storage server is programmed for management, version control, and scheduling of replication of multiple types of data storage objects including iSCSI LUNs and file systems. The version control determines if two data storage objects are the same or have a common base so that only a difference needs to be transmitted for replication or restoration. A replication job may specify a 'one-to-many' replication or a cascaded replication, and any snapshot retention policy is propagated during a cascaded replication. Concurrent replication sessions to the same destination are paced in accordance with respective allocation shares of the reception bandwidth. File handle information is replicated so that a file handle issued by a primary data storage server can be used for accessing a replicated file in a secondary data storage server.
