Windows NT and Windows 2000 clients support LAN-free data movement, which shifts the movement of client data from the communications network to a storage area network (SAN). Shifting the client data movement from the communications network to a SAN decreases the load on the Tivoli Storage Manager server.
The SAN provides a path that allows you to backup, restore, archive, and retrieve data to and from a SAN-attached storage device. Client data moves over the SAN to the storage device via the Tivoli Storage Manager Storage Agent. The Tivoli Storage Manager Storage Agent must be installed on the same system as the client.
Server-free backup differs from LAN-free backup in that the client does not read or write the information to and from storage. See Appendix B, SAN-Based Server-Free Image Backup for more information about server-free backup.
To enable LAN-Free support, you must install and configure the Tivoli Storage Manager Managed System for SAN feature on the client workstation. For more information, refer to Tivoli Storage Manager for Windows Managed System for SAN Storage Agent User's Guide, GC32-0785 .
After installing and configuring the Tivoli Storage Manager Managed System for SAN feature on the client workstation, you can use the following options to enable LAN-Free data movement:
