Secondary data storage and recovery system
First Claim
1. A system for providing secondary data storage and recovery services for one or more networked host nodes comprising:
- 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.

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.

13. A software suite for providing secondary storage and recovery services to a plurality of networked nodes comprising:
-
a portion for configuring network nodes for services;
a portion for ordering services and for generating metadata about data generated for secondary storage;
a portion for providing data write validation; and
a portion for receiving data and for preparing the received data for storage. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A method for passive acquisition and write validation of data generated by one or more networked host nodes for secondary storage in a SAN-based data storage and recovery network including steps of:
-
(a) generating data for primary storage;
(b) generating metadata describing the data generated for primary storage;
(c) sending the data and metadata to a primary SAN storage device;
(d) acquiring passive access to data traveling the data path between the generating node and the primary SAN device the data mirrored over the access line to a secondary storage server;
(e) receiving, at the secondary storage server, an exact copy of the data stream that passes the splitter; and
(f) comparing metadata sent with the actual data against locally stored metadata to validate or invalidate the write data. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
