Abstract
A data storage server is programmed with common software modules for management, version control, and scheduling of replication of data storage objects of multiple data storage object types. The multiple data storage object types include iSCSI LUNs, file systems, virtual servers, directories, and files. 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. The scheduler controls the timing of snapshot creation and deletion, and replication transmission to one or more remote destinations. The scheduler may ensure that a replica of a data storage object is out-of-sync with the original of the data storage object by no more than a specified amount of time.
