Improved Recovery and Disaster Recovery


Recovery performance on Windows 2000 and Linux is enhanced by utilizing fast image restores.

Fast restore because no overhead for file creationOptimized for backup/restore of entire file systemComplements progressive backupFast, non-disruptive file-system image backup Backup/restore can be over LAN or LAN-free

Multi-Session Restore

Recovery performance is enhanced with parallel restores provided by multiple client-server sessions

Limited by Number of sequential-access volumes with data to be restored Mount points Client's resourceutilization option


The time to create recovery tapes for local and offsite vaulting is reduced with simultaneous writes to multiple copy storage pools during backup and archive.

Target pools can have different device classesShould be used in conjunction with incremental storage pool backup

Improved Availability


Application availability is improved during backups by providing online, non-disruptive image backups.

Fast, non-disruptive file-system image backupOptimized for backup/restore of entire file systemComplements progressive backupFast restore because no overhead for file creationBackup/restore can be over LAN or LAN-free

AIX TSM b-a & HSM Client Support HACMP Cluster failover support for B/A and HSM clients on AIX

Automatically resume normal operation on another node after failover– In flight scheduled processes automatically restarted if within schedule

start window– Otherwise, normal operation resumes with next scheduled event

Support for automatic fallback when failed node rejoins the cluster (if user chooses this behavior)

TSM API client on AIX is also HACMP cluster enabled Applications using the API, however, may have additional requirements for

cluster support. Refer to the documentation for the specific application to determine if it supports cluster failover

Tivoli Storage Manager Server free – V5.1

LAN Free

Processor Free


Server-Free Backup/Restore (limited availability) The impact on application servers during backups is

minimized with server-free data movement. Reduce TSM client and/or server CPU utilization Eliminates data movement on the LAN

– Implementation of the SCSI-3 extended copy command will cause data to be transferred directly between devices over the SAN or SCSI bus

Improve scalability – The TSM server will be able to handle more concurrent client connections and server

operations because it will not be copying data– The TSM client processor will likewise be able to handle more application load because

cycles will not be needed to read and send data buffers to the server Improve performance for data movement operations

On-line server-free image backup Supports Windows NT/2000 TSM server Windows 2000 b/a clients San Data gateway

Other Enhancements


Journal Based Backup The improved backup performance available with journal based

backup is now supported on cluster configurations. Remove query of active files on server - Thus reduce data transfer from server to client Remove scan of local filesystem Eliminate list processing

– Reduce memory requirement– Reduce processing requirement

Implemented on Windows NT/2000 using Win APIs Eliminate most queries to either the TSM server or the local file

system TSM monitors file changes within filesystems Only new/changed files are backed up

Fault tolerant Automatically reverts to normal incremental backup if fault detected

Dynamic addition/removal of files systems to be journaled Setup wizard changes


AIX TSM Server Direct I/O Improved throughput and reduced CPU utilization on AIX servers is

made possible with Direct I/O. Helps reduce CPU utilization and improves I/O throughput

Target 10% throughput improvement to disk– Previously when using JFS file systems for DB, LOG, and STORAGE

POOL volumes on AIX, the AIX Virtual Memory Manager (VMM) caches read/write requests in memory in case sequential blocks are read/written

Target 30% reduction in CPU usage– Now TSM reduce CPU utilization by bypassing the VMM cache when

writing to TSM JFS volumes

AIXDIRECTIO option is added to the server options


TSM Wizard UpdatesSimplified TSM Server Install Option to produce a minimal TSM server configuration on Windows

Can complete initial backup to disk quickly The minimal configuration option involves

Present Initial Configuration Dialog with choice of Default or Minimal configuration

– The difference between the two configurations is whether the server initialization wizard is the only wizard run or whether several wizards are run in addition to the server initialization wizard

Wizard Support: Server Free, Journal Based backup & TDP NDMP Server Initialization wizard updated Node configuration wizard updated Device Configuration wizard updated


Web Interface Updates

Usability updates to Web Interface Appearance improved by updating the images in the GUIs

The HUB, splash screens, and images updated in the TSM native GUIs for the Windows and Mac platforms and in the TSM Web Client GUIs

The UNIX GUI updated its splash screen Toolbars and tool tip help will be added to the TSM Web Client GUI

TSM Web Client GUI is now a Swing-based web applet Uplifted the current TSM Web Client to use Swing-based components Swing components have built-in accessibility support and improved keyboard

navigation Utilized the native look and feel of the platform running the browser


TSM HP LAN-Free backup-restore TSM HP storage agent available on HP platform

LAN-Free support equivalent to LAN-Free support on other platforms Supported Configurations

HPUX 11.0 or HP UX 11i Cannot use device type generic tape Any hardware configuration that the hardware vendors support

Additional device support including optical Benefits

Improve storage resource utilization Minimizes LAN disruption

– Offload LAN Traffic– More flexible backup window

Scheduling and policy management to optimize shared resource Better performance over slow LAN


LAN-Free LAN-Free backup-restore • Fibre Channel SCSI

not good for communication flow between host processors

• LAN: control flow, directory/file names and attributes

Consistent Client Return Codes Improved automation enablement for TSM scheduler and external

scheduler Reliable, Consistent & Documented Return Codes Command line client & scheduler enhanced

Facilitates automation of client operations via user-written scripts Administrators can now distinguish between

– Scheduled backups that completed successfully with no skipped files– Scheduled backups that completed successfully with one or more

skipped files If PRESCHEDULECMD command ends with non-zero return code,

scheduled event will not run– Ensures that scheduled events will not run if prerequisite commands do

not complete successfully


CRC - Cyclic Redundancy Checking TSM Server and Client - CRC Verifies the data that is correctly transferred from the client, stored on the

server, and returned to the client New communication and SAN hardware products are more susceptible to data loss,

thus the need for checksums Can be used in problem determination to isolate possible data transfer problems CRCs with the data backed up and restored and can be checked by TSM server

and client

Benefits misconfigured or malfunctioning network or storage hardware Additional assurance to the customer that data was successfully handled Optional: Externals updated to allow for turning CRC on and off
