Tivoli Storage Manager for Windows: Administrator's Guide


Technical Changes for Version 4 Release 1--July 2000

The following changes have been made for this edition:

Support for Mobile Clients
This enhancement allows mobile users to backup files and afterwards make subsequent backups to the portion (a subfile) of the file that has changed, rather than the entire file. This type of backup allows remote or mobile users using modems with limited bandwidth to reduce connection time, network traffic, and the time it takes to do a backup. This enhancement also uses encryption to protect clients' data. See Enabling Clients to Use Subfile Backup.

Support and Enhancements for Windows 2000
Removable Storage Manager (RSM) is a service included with Windows 2000 that facilitates communication among applications, robotic changers, and media libraries. It enables multiple applications to share local robotic media libraries and tape or disk drives, and manage removable media with a single-server system. RSM is managed by using a Microsoft Management Console (MCC) console. See Using Removable Media Managers With Tivoli Storage Manager.

Managed System for SAN Environments
Tivoli Storage Manager has been enhanced to support LAN-free data movement in storage area network (SAN) environments. Support is currently limited. The support allows client data to move directly from the client system to a server-managed storage device on the SAN, instead of moving first from the client system to the server over the LAN and then to the device. This enhancement reduces data movement on the LAN so that more bandwidth is available to other applications. This enhancement also increases tape library sharing for multiple TSM servers. See Configuring TSM Clients to Directly Access SAN-Attached Devices.

Storage Area Network (SAN) Tape Library Sharing
Tivoli Storage Manager takes advantage of SAN-attached tape libraries by sharing devices among TSM servers. One of the servers acts as the library manager and the other servers are library clients. The other servers can be on different operating systems, as long as the servers also support tape library sharing. See Configuring TSM Servers to Share SAN-Connected Devices.

Licensing
A client is now licensed as a managed system. A managed system can be a client or server that requires backup services from the TSM server. Each managed system that moves data to and from storage over a local area network requires a Managed System for LAN license. Each managed system that moves data to and from storage over a storage area network requires a Managed System for SAN license. See Licensing Tivoli Storage Manager for details. The following table lists changes to license names:

Table 1. License Name Changes

Former name Current name Notes
Client Connections Managed System for LAN and Managed System for SAN A managed system that moves data to and from storage both on a LAN and on a SAN, requires only the Managed System for SAN license.
OpenSystem AFS/DFS Support The S/390(R) platform includes the S/390 UNIX(R) client as part of Managed System for LAN.
Extended Device Support Managed Library
