Secondary data storage and recovery system
First Claim
1. A system to provide secondary data storage and recovery services to at least one networked host node storing data in an array of primary storage devices each coupled to the at least one host node by dedicated data paths, comprising:
- a host node to connect at least one of a primary storage device and a secondary storage subsystem to a network to acquire data;
the primary storage to store the data generated by the host node;
the secondary storage subsystem including a server executing a server application managing data backup and recovery services by the secondary storage subsystem, wherein the secondary storage subsystem is comprised of at least one of a dedicated server node and a PC node, and wherein the data is received by at least one of a specially adapted line card installed in the secondary storage subsystem and a network adaptor card; and
at least one data path splitter installed one per dedicated data path existing between the at least one host and the primary storage device, wherein the splitter mirrors data transmitted in the dedicated data paths, and streams the mirrored data to the secondary storage subsystem, wherein the data path splitter is comprised of a hardware data splitter of at least one of an optical type and an electrical type, depending on the type of network line used.

Abstract
A system for providing secondary data storage and recovery services for one or more networked host nodes has a server application for facilitating data backup and recovery services; at least one client application for facilitating host node configuration to receive services; a secondary data storage medium; and at least one mechanism for passive acquisition of data from the one or more host nodes for storage into the secondary data storage medium by the server application. In a preferred embodiment secondary storage is streamlined through continuous data backup and enhanced by elimination of redundant write data.

23. A method of configuring at least one networked host node to provide secondary data storage and recovery services, wherein the at least one networked host node stores data in an array of primary storage devices each coupled to the at least one host node by dedicated data paths, the method comprising:
-
configuring a secondary storage sub-system including a server executing a server application managing data backup and recovery services by the secondary storage subsystem, wherein the secondary storage sub-system is comprised of at least one of a dedicated server node and a PC node, and wherein the data is received by at least one of a specially adapted line card installed in the secondary storage sub-system and a network adaptor card; and configuring at least one data path splitter installed one per dedicated data path existing between the one or more hosts and a primary storage device, wherein the splitter mirrors data transmitted in the dedicated data paths, and streams the mirrored data to the secondary storage subsystem, wherein the at least one data path splitter is comprised of at least one hardware data splitter of at least one of an optical type and an electrical type, depending on the type of network line used. - View Dependent Claims (24, 25, 26, 27)

28. A method comprising:
-
providing secondary data storage and recovery services to at least one networked host node storing data in an array of primary storage devices each coupled to the at least one host node by dedicated data paths; executing a server application managing data backup and recovery services using a secondary storage subsystem including a server;
wherein a secondary storage subsystem is comprised of at least one of a dedicated server node and a PC node, and wherein the data is passively received by at least one of a specially adapted line card installed in the secondary storage subsystem and a network adaptor card;mirroring data transmitted on a dedicated data path existing between the at least one host and a primary storage device using at least one splitter installed one per dedicated data path, wherein the at least one data path splitter is comprised of at least one hardware data splitter of at least one of an optical type and an electrical type, depending on the type of network line used.; and streaming the mirrored data to the secondary storage subsystem. - View Dependent Claims (29, 30, 31)
