Tivoli Storage Manager for UNIX Backup-Archive Clients Installation and User's Guide
Following is a summary of changes since Tivoli Storage Manager Version
4.2:
- Support for Cyclical Redundancy Checking (CRC)
- Tivoli Storage Manager supports cyclical redundancy checking (CRC) to
verify that data is not being corrupted in transfer during a backup or restore
session.
- 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. Data Protection for NDMP enables backup
and restore support on the Tivoli Storage Manager Windows NT, 2000, XP, and
Windows.NET, AIX, and Solaris servers for NAS file servers from Network
Appliance. Data Protection for NDMP is available only with IBM
Tivoli Storage Manager Enterprise Edition. See Data Protection for NDMP Version 5.1 Requirements (Enterprise Edition only) for Data Protection for NDMP requirements. See Appendix C, Backing Up NAS File Systems Using NDMP for information on how to back up and
restore NAS file system images using the Web client and command line
client.
- Support for Logical Volume Backup as a Single Object (Image Backup) on
Linux86 Client
- The Linux86 client is enhanced to support a logical volume image backup of
file systems and raw volumes. The Tivoli Storage Manager server does
not track individual files in the file system image. File system images
are tracked as individual objects and management class policy will be applied
to the file system image as a whole. See Performing an Image Backup for more information.
- Support for Online Image Backup of File Systems and Raw Logical Volumes on
Linux86 Client
- The traditional offline image backup prevents access to the
volume by other system applications during the operation. For Linux86
only: Tivoli Storage Manager performs an online
image backup of file systems residing on a logical volume created by the Linux
Logical Volume Manager, during which the volume is available to other system
applications. See Performing an Image Backup for more information.
- LAN-Free Data Movement Support on HP-UX Client
- Tivoli Storage Manager supports LAN-Free data movement in a storage area
network (SAN) environment for the HP/UX client. 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.
- Enhanced Web Client Interface
- The Web client interface is enhanced to support a JRE 1.3.1
Swing-enabled browser. The Web client facilitates the use of assistive
devices for users with disabilities and contains improved keyboard
navigation. The native look and feel of the platform running the
browser is preserved. See Starting a Web Client Session for more information.
- Support for the z/OS file system on the OS/390 Client
- Tivoli Storage Manager supports backup and restore of the z/OS file system
on the OS/390 Client. See Incremental for more information.
- Support for the Sun Quick File System (QFS) 3.5.0 on the the
Solaris Client
- Tivoli Storage Manager supports backup, restore, archive and retrieve of
the QFS file system on the Solaris client. QFS is a high-performance
file system that enables file sharing in a SAN. It eliminates
performance bottlenecks resulting from applications using very large file
sizes. See Incremental for more information.
- Support for High Availability Cluster Multi Processing (HACMP) on AIX
Client
- Tivoli Storage Manager supports HACMP failover on AIX. This allows
the client to continue operating in the event of an HACMP node failover and
fallback.
- Multiple Session No Query Restore
- The backup-archive clients can now utilize multiple restore sessions for
no query restore operations, increasing the speed of restores. This is
similar to the multiple backup session support. It exploits the mount
point available on the server. If data is backed up on multiple tapes,
and if the server has multiple mount points available, then the restore starts
a session for each tape, up to the number your administrator
configures. See Resourceutilization for more information.
- Consistent Client Return Codes
- Reliable, consistent, and documented return codes have been added to the
command line client and the scheduler. This facilitates automation of
client operations via user-written scripts. By using the QUERY
EVENT command with the FORMAT=DETAILED option,
administrators can now distinguish between scheduled backups that completed
successfully with no skipped files and scheduled backups that completed
successfully with one or more skipped files. Also if you use the
processing optionpreschedulecmd to run a command, and that command
returns a non-zero return code, the scheduled event will not run. This
ensures that scheduled events will not run if prerequisite commands do not
complete successfully. See Return Codes from the Command Line Interface, Preschedulecmd/Prenschedulecmd, and Postschedulecmd/Postnschedulecmd for more
information.
