Tivoli Storage Manager for Windows Using the Backup-Archive Client


Summary of Changes for Tivoli Storage Manager

This section summarizes changes made to the Tivoli Storage Manager product and this publication.


Technical Changes for Version 4.2.1 - September 2001

Following is a summary of changes since Tivoli Storage Manager Version 4.2:

Support for Processing Network Attached Storage (NAS) File System Images
Tivoli Storage Manager supports backup and restore of network attached storage (NAS) file system images to tape drives or libraries that are locally attached to NAS file servers. Tivoli Data Protection for NDMP enables backup and restore support on the Tivoli Storage Manager Windows NT and Windows 2000 servers for NAS file servers from Network Appliance. Tivoli Data Protection for NDMP is a separately priced and licensed product. See "Tivoli Data Protection for NDMP Version 4.2.1 Requirements" for Tivoli Data Protection for NDMP requirements. See Appendix A, "Backing Up NAS File Systems" for information on how to back up and restore NAS file system images using the Web client and command line client.

Support for LAN-Free Data Movement
Tivoli Storage Manager supports LAN-Free data movement in a storage area network (SAN) environment. LAN-Free data movement allows client data to move directly from the client to a SAN-attached storage device. Shifting the client data movement from the communications network to a SAN decreases the load on the server. This allows the server to support a greater number of simultaneous client connections. See "LAN-Free Data Movement" for more information.

Technical Changes for Version 4.2 - June 2001

Following is a summary of changes since Tivoli Storage Manager Version 4.1:

Enhancement for Archiving Files
You can use the v2archive option with the archive command to archive only files to the server. Directories that exist in the path of the source file specification will not process. See V2archive for more information.

Windows NT and Windows 2000 Unicode-Enabled Clients
Unicode is a universal character encoding standard that supports the interchange, processing, and display of text that is written in any modern world language. Unicode file spaces provide support for multi-lingual workstations without regard for the current locale. Beginning with Tivoli Storage Manager Version 4.2, the Windows NT and Windows 2000 clients are Unicode-enabled. Windows NT and Windows 2000 clients support the Unicode code page for file, directory, and file space names. See "Migrating to the Unicode-Enabled Client" for more information.

Firewall Support
In most cases, the Tivoli Storage Manager server and clients can operate across a firewall. The firewall administrator must open the firewall ports needed for client and server communication. See "Tivoli Storage Manager Firewall Support" for more information.

Support for Journal-Based Backup
Tivoli Storage Manager supports journal-based backup. Journal-based backup can increase backup performance. With this process, the client does not scan the local file system or obtain information from the server to determine which files to process. Journal-based backup also reduces network traffic between the client and server. See "Journal-Based Backup (Windows NT, 2000 only)" for more information.

Mobile Dial-Up Support
Tivoli Storage Manager supports remote network connections to a server. With a remote network connection, mobile users no longer need to dial-in to their company network for a scheduled backup. Tivoli Storage Manager automatically establishes a connection prior to the scheduled backup. If the connection fails, Tivoli Storage Manager reestablishes the connection before attempting the backup. See "Mobile Dial-Up Support" for more information.

Using Communication Method Specified in Active Directory
When you specify the usedirectory, the Tivoli Storage Manager client ignores commmethod parameters in the client options file and queries the Active Directory for the communication method and server with which to connect. This option is valid for Windows 2000 only. See Usedirectory for more information.

Restore of Inactive System Objects
Tivoli Storage Manager supports query and restore of inactive system objects through the command line interface. You can restore system objects via point in time restore. Valid with Windows 2000 only.

Support for Inactivating Backup Objects
Tivoli Storage Manager allows you to inactivate backup objects. Use the expire command to inactivate the backup objects listed in a file specification or designated by the filelist option. See Expire for more information.

Filelist Support for Command Processing
Tivoli Storage Manager supports use of a file that contains a list of files to be processed for a command. Use the filelist option to process a specific list of files. The client opens the specified filelist and processes each file according to the specific command. See Filelist for more information.

Enhancements for the Client Acceptor Service (CAD)
The Tivoli Storage Manager Client Acceptor Service can now manage the Scheduler and the Web client, reducing the number of background processes on your workstation. This also resolves memory retention problems that may occur when using traditional methods of running the scheduler. See "Managing the Client Scheduler Using the Client Acceptor Service" for more information.

Enhancements for Compression Processing
You can include or exclude a file or groups of files from compression processing during a backup or archive operation. See Chapter 7, "Creating an Include-Exclude List" for more information.

Enhancements for Adaptive Subfile Backup Processing
You can include or exclude a file or groups of files for Adaptive Subfile Backup Processing during a backup or restore operation. See Chapter 7, "Creating an Include-Exclude List" for more information.

Enhancements for Restore of Local Backup Sets
The Tivoli Storage Manager GUI can restore a backup set on an attached device on a Windows NT standalone workstation without requiring a server connection. See "Restoring Data from a Backup Set" for more information.
