New for the server in Version 6.3.3Server fix pack 6.3.3 contains several new features, in addition to fixes forproblems.

The server that is included with the Tivoli Storage Manager and IBM Tivoli StorageManager Extended Edition V6.4 products is at the V6.3.3 level. The V6.3.3 server isalso available for download separately, as a fix pack for current users of V6.3.

LDAP-authenticated passwordsIBM Tivoli Storage Manager server V6.3.3 can use an LDAP directory server toauthenticate passwords. LDAP-authenticated passwords give you an extra level ofsecurity by being case-sensitive, offering advanced password rule enforcement, anda centralized server on which to authenticate them.

You must have an LDAP directory server on which to authenticate a hashrepresentation of the password. After you configure the Tivoli Storage Managerserver, you can authenticate administrator and node passwords with the LDAPdirectory server.

The two methods of authentication are LDAP and LOCAL. LOCAL means that thepassword is authenticated with the Tivoli Storage Manager server.

Passwords that are authenticated with the Tivoli Storage Manager server are notcase-sensitive. All passwords can be composed of characters from the followinglist:a b c d e f g h i j k l m n o p q r s t u v w x y zA B C D E F G H I J K L M N O P Q R S T U V W X Y Z0 1 2 3 4 5 6 7 8 9~ ! @ # $ % ^ & * _ - + = ` | ( ) { } [ ] : ; < > , . ? /

New Tivoli Enterprise Portal monitoring workspaces are:v Activity summary workspace, which provides data about server and clientoperations for both virtual and non-virtual environments.

v Sessions workspace, which provides a view of all the active client sessionsrunning on the specified server.

Additional VMware backup information is now provided in the Tivoli StorageManager server activity log and summary table for Data Protection for VMwareoperations. This new information provides improved data collection and reportingcontent when you use reporting facilities such as Tivoli Common Reporting.

A new option to enable LDAP authentication, when creating and configuringmonitoring agent instances.

The improved ability to exclude, or filter-out message numbers, to narrow results.

New for IBM Tivoli Storage Manager Version 6.3 xxvii

Existing IBM Tivoli Monitoring users can now install the small agent package, andremotely deploy monitoring agents without having to download the larger TivoliMonitoring for Tivoli Storage Manager package.Related reference:Cognos status and trend reports on page 810

Control for inactive NDMP operation connectionsTransmission Control Protocol (TCP) keepalive is a mechanism by which small packetsof data are sent across the network at predefined intervals. The packets prevent along-running, inactive connection from being closed by firewall software thatdetects and closes inactive connections. With this release, you can enable the TCPkeepalive function for control connections of network data-management protocol(NDMP).Related tasks:Enabling TCP keepalive on page 214

Enhancements for expiration processingImprovements for expiring inventory are available with this release. Nodeprocessing can now be spread across more than one thread in parallel, at the filespace level. This change in process helps distribute the workload and moreefficiently avoid bottlenecks for nodes that use virtual servers.Related reference:Using commands to control expiration processing on page 505

New for the server in Version 6.3.1Server fix pack 6.3.1 contains new features, in addition to fixes for problems.

Data validation during read/write operations to tapeWith logical block protection, IBM Tivoli Storage Manager includes a cyclicredundancy check (CRC) value at the end of each logical block of data to bewritten to tape. You can specify CRC data-block validation during read and writeoperations, or only during write operations.

You can use logical block protection only with the following types of drives andmedia:v IBM LTO5 and laterv IBM 3592 Generation 3 drives, and later, with 3592 Generation 2 media, and later

New for the server in Version 6.3.0New features and other changes are available in the Tivoli Storage Manager V6.3server.

Node replicationNode replication is the process of incrementally copying or replicating client nodedata from one server of Tivoli Storage Manager to another server of Tivoli StorageManager for the purpose of disaster recovery.

The server from which client node data is replicated is called a source replicationserver. The server to which client node data is replicated is called a target replicationserver.

Node replication avoids the logistics and security exposure of physically movingtape media to a remote location. If a disaster occurs and the source replication

xxviii IBM Tivoli Storage Manager for Linux: Administrator's Guide

server is unavailable, backup-archive clients of Tivoli Storage Manager can recovertheir data from the target replication server. If you cannot recover the sourcereplication server, you can convert client nodes to nonreplicating nodes for storeoperations on the target replication server.

If you use the export and import functions of Tivoli Storage Manager to store clientnode data on a disaster-recovery server, you can convert the nodes to replicatingnodes. When replicating data, you can also use data deduplication to reducebandwidth and storage requirements.

Tivoli Storage Manager V6.3 servers can be used for node replication. However,you can replicate data for client nodes that are at V6.3 or earlier. You can alsoreplicate data that was stored on a Tivoli Storage Manager V6.2 or earlier serverbefore you upgraded it to V6.3.

You cannot replicate nodes from a Tivoli Storage Manager V6.3.3 server to a serverthat is running on an earlier level of Tivoli Storage Manager.Related tasks:Chapter 34, Replicating client node data, on page 951

Deduplication of NetApp file-server dataDeduplication of data that belongs to network-attached storage (NAS) file-serversis disabled by default. To enable deduplicaton of NetApp file-server data, use thenew ENABLENASDEDUP server option.

Database table and index reorganizationIf automatic table and index reorganization is affecting server performance, youcan manually schedule reorganizations.

Automatic backup-archive client deploymentIBM Tivoli Storage Manager, Version 6.3 can be scheduled to automatically deploybackup-archive client software to all workstations that have the backup-archiveclient installed.

You can deploy backup-archive clients on Microsoft Windows operating systemsfrom a fix pack or interim fixes for all releases at V5.4 or later. You can migrate theBackup-Archive Client to a newer version, release, modification, or fix pack levelthat is V5.5 and later.

You can deploy backup-archive clients on operating systems other than Windowsfrom all releases at V5.5 or later. These Backup-Archive Clients can go to any laterversion, release, modification, or fix level. You can coordinate the updates to eachBackup-Archive Client from the Administration Center.

Multistream database backup and restore processingMultiple, concurrent data streams can reduce the amount of time that is requiredto back up or restore the database. You can specify multiple, concurrent datastreams for automatic or manual database-backup operations.

During restore operations, the Tivoli Storage Manager server attempts to use thesame number of data streams that you specified for the backup operation. Forexample, suppose that you specify four data streams for a database backupoperation. During a restore operation, the server attempts to use four drives. If onedrive is offline and unavailable, the server uses three drives for the restoreoperation.

New for IBM Tivoli Storage Manager Version 6.3 xxix

The benefit of multiple, concurrent data streaming depends on the size of thedatabase. In general, if the database is less than 100 GB, the amount of time thatyou can save is relatively small. Multiple, concurrent data streaming also usesmore volumes. If the volumes are high-capacity and if you use data compression,the result can be wasted space.

Tivoli Monitoring for Tivoli Storage Manager updatesIBM Tivoli Monitoring for Tivoli Storage Manager, previously referred to as theReporting and Monitoring feature, has an improved installation wizard. Cognos isnow included for custom report creation.

Updates to Tivoli Monitoring for Tivoli Storage Manager include the followingitems:v Cognos Business Intelligence V8 is an integrated business intelligence suite thatis provided as part of Tivoli Common Reporting.
