Tivoli Storage Manager for Windows 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 A, 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
Windows 2000 Client
- The Windows 2000 client is enhanced to support a logical volume image
backup of file systems and raw volumes. You can use the native GUI, the
command line interface, and the Web client GUI to create an image of file
systems and raw logical volumes on the Tivoli Storage Manager server.
NTFS and FAT32 file systems are supported. 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 (Windows 2000 Only) for more information.
- Support for Online Image Backup of File Systems and Raw Logical Volumes on
Windows 2000 Client
- The traditional offline image backup prevents access to the
volume by other system applications during the operation. For Windows
2000 only: If the Logical Volume Snapshot Agent (LVSA) is
installed and configured, Tivoli Storage Manager performs an online
image backup, during which the volume is available to other system
applications. See Performing an Image Backup (Windows 2000 Only) for more information.
- Support for SAN-Based Server-Free Data Movement
- The Windows 2000 client supports SAN-based server-free data movement that
off-loads data movement processing from the client and server processor and
from the LAN during image backup and restore operations. Data is
transferred directly between client disks and SAN-attached storage devices by
a third-party copy function initiated by the Tivoli Storage Manager
server. See Enableserverfree 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.
- 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.
