Tivoli Storage Manager for UNIX Using the Backup-Archive Clients


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 B, "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.

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.

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 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.

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 Daemon (CAD)
The Tivoli Storage Manager Client Acceptor Daemon 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 Daemon" for more information.

Support for Data Encryption
You can now encrypt data sent to the server during backup and archive operations with standard DES 56-bit encryption. Use the include.encrypt and exclude.encrypt options for file encryption. See "Encryption" for more information. Also see the encryptkey option Encryptkey.

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 "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 UNIX standalone workstation without requiring a server connection. See "Restoring Data from a Backup Set" for more information.
