IBM Tivoli Storage Manager for UNIX: Backup-Archive Clients Installation and User's Guide


Summary of changes for Tivoli Storage Manager

This section summarizes changes made to the Tivoli Storage Manager product and this publication. Technical changes to the text are indicated by vertical lines to the left of the change.


|Technical changes for version 5.2.2 - December 2003

|The following changes have been made to the product for this edition: |

|Tivoli Storage Manager backup-archive client Linux on iSeries
|The Tivoli Storage Manager backup-archive client supported features on |Linux for iSeries are the same as those supported by the Linux for pSeries |client. See Chapter 1, Installing Tivoli Storage Manager for environment and installation information.

|Tivoli Storage Manager backup-archive client for Linux on Intel Itanium
|The Tivoli Storage Manager backup-archive client for Linux on Intel |Itanium (Linux IA64 client) supports these file systems and their ACLs: |xfs, ext2, and ext3. As with the Linux for X86 client, the Linux IA64 |client supports the reiserfs file system, but not its ACLs.

|The Tivoli Storage Manager Linux IA64 client supports the same functions as |the Linux86 client, except the following: |

|See Chapter 1, Installing Tivoli Storage Manager for environment and installation information.

|Backup and restore support for IBM TotalStorage SAN File Systems
|Backup and restore for IBM TotalStorage SAN File Systems is supported on |the AIX 5.1 client. See File system and ACL support for more information.

|Support for controlling symbolic link processing
|Tivoli Storage Manager treats symbolic links as actual files and backs |them up. However, the file referenced by the symbolic link is not |backed up. In some cases symbolic links can be easily recreated and |need not be backed up. In addition, backing up these symbolic links can |increase backup processing time and occupy a substantial amount of space on |the Tivoli Storage Manager server. You can use the |exclude.attribute.symlink option to exclude a file or |a group of files that are symbolic links from backup processing. If |necessary, you can use the include.attribute.symlink |option to include symbolic links within a broad group of excluded files for |backup processing. For additional information, see : |

|Support for WebSphere Application Server (WAS) security
|If WAS security is enabled, user name and password validation for Data |Protection for WebSphere Application Server is required. If you do not |set the WAS password for the security, the backup will failover to an offline |backup. It is recommended to set the WAS security password to perform |consistent backups. Use the set waspassword command to set |the user name and password for each installation of WAS on your |machine. You only need to perform this task once, unless you change |your WAS user name or password. You can only perform this task on the |Tivoli Storage Manager command line. See Set Waspassword for more information.

|Removal of operand limits for backup and archive operations
|Use the removeoperandlimit option to specify that Tivoli |Storage Manager removes the 20-operand limit for UNIX-family platforms. |If you specify the removeoperandlimit option with the |incremental, selective, or archive commands, |the 20-operand limit is not enforced and is restricted only by available |resources or other operating system limits. See Removeoperandlimit

|Multi-session backup session enhancements
|Use the collocatebyfilespec option to specify whether the |Tivoli Storage Manager client uses only one server session to send objects |generated from one file specification. Setting the |collocatebyfilespec option to yes eliminates |interspersing of files from different file specifications, by limiting the |client to one server session per file specification. Therefore, if you |store the data to tape, files for each file specification are stored together |on one tape (unless another tape is required for more capacity). See Collocatebyfilespec for more information.

|Language support expanded to include Russian, Hungarian, Polish, and Czech
|Tivoli Storage Manager client language packs are available in Russian, |Hungarian, Polish, and Czech language locales. See Setting language environment variables for more information. |

Technical changes for version 5.2 - April 2003

The following changes have been made to the product for this edition:

Support for backing up files from one or more file space origins
You can use the Tivoli Storage Manager command line client to create and back up a group containing a list of files from one or more file space origins to a virtual file space on the Tivoli Storage Manager server. A group backup allows you to create a point-in-time backup of a group of files that is managed as a single logical entity. See Group backup: Backing up files from one or more file spaces for more information.

Network Data Management Protocol (NDMP) file-level restore
NDMP support is enhanced to allow you to restore individual files from your Network Attached Storage (NAS) file system image backups. Use the toc option with the include.fs.nas option in your client system options file (dsm.sys) to specify whether Tivoli Storage Manager saves Table of Contents (TOC) information during a NAS file system image backup. If you save TOC information, you can use the Web client or the Tivoli Storage Manager server restore node command to restore individual files or directory trees from the NAS file system image that you specify. See Toc for more information.

NDMP support is available only on IBM Tivoli Storage Manager Extended Edition.

Support for processing EMC Celerra NAS file system images
Through support of NDMP, Tivoli Storage Manager Windows, AIX, and Solaris servers can efficiently back up and restore NAS file system images to tape drives or libraries that are locally attached to Network Appliance and EMC Celerra NAS file servers. NDMP support is available only on IBM Tivoli Storage Manager Extended Edition. See NDMP support requirements (Extended Edition only) for NDMP support requirements. See 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.

Support for backup and restore of the WebSphere Application Server
If you installed the Data Protection for WebSphere Application Server, you can use Tivoli Storage Manager to back up the Version 5.0 WebSphere Application Server Network Deployment Manager (contains setup, application files, and configuration information) or the Application Server to the Tivoli Storage Manager server. You can restore this information from the Tivoli Storage Manager server and use it to recover a corrupted node application or an entire node (or nodes) in the event of an accident or disaster.

Data Protection for WebSphere Application Server is a separately priced and licensed product. Data Protection for WebSphere Application Server is only supported on a Tivoli Storage Manager Version 5.2 server and client. Data Protection for WebSphere Application Server is supported on the AIX 5.1 with Maintenance level 2; Solaris 8; Red Hat Advanced Server 2.1 for x86, SuSE Linux 7.3 for x86, SuSE SLSE 7 for x86, and United Linux 1.0 for x86 clients only.

See Backing up the WebSphere Application Server (WAS) for more information.

Enhancements for command line image restore operations
You can use the verifyimage option with the restore image command to specify that you want to enable detection of bad sectors on the destination target volume. If bad sectors are detected on the target volume, Tivoli Storage Manager issues a warning message on the console and in the error log. See Verifyimage for more information.

If bad sectors are present on the target volume, you can use the imagetofile option with the restore image command to specify that you want to restore the source image to a file. Later, you can use a 'dd' utility (available on Unix) or its equivalent to copy data from this file to a logical volume. See Imagetofile for more information.

Support for an external snapshot provider in the backup-archive clients
Use the snapshotroot option with the incremental, selective, or archive commands in conjunction with a third-party application that provides a snapshot of a logical volume, to associate the data on the local snapshot with the real file space data that is stored on the Tivoli Storage Manager server. The snapshotroot option does not provide any facilities to take a volume snapshot, only to manage data created by a volume snapshot. See Snapshotroot for more information.

Enhancements to the Web client interface
The following functions are now supported in the Tivoli Storage Manager Web client interface:
Access Another Node
Displays the backup versions and archive copies of another node. You can then restore the backup versions or retrieve the archives from the other user to your workstation. You must have authorization to access the stored data of another node.
Node Access List
Allows you to authorize other users to access your backup versions and archive copies.
View Policy Information
Displays storage management policy information for your node.

Enhanced firewall security
Security for back up and restore operations and Tivoli Storage Manager administrative functions is enhanced to allow the Tivoli Storage Manager server to control whether the server or client initiates sessions through a firewall. See Sessioninitiation for more information.

Both the server and client can also specify a separate TCP/IP port number on which the server is waiting for requests for administrative client sessions, allowing secure administrative sessions within a private network. See Tcpadminport for more information.

Veritas file systems, ACLs, and Veritas Volume Manager support on AIX (32-bit and 64-bit) clients
Tivoli Storage Manager supports backup, restore, archive, and retrieve of Veritas file systems (VxFS) including ACLs on the AIX (32-bit and 64-bit) clients. Image backup and restore of Veritas Volume Manager logical volumes is also supported.

Automounter support for Linux86 and Linux390 clients
The Tivoli Storage Manager Linux86 and Linux390 clients now support the back up of automounted NFS and loopback file systems. Use the automount option with the domain option to specify all automounted file systems the Tivoli Storage Manager client tries to mount at the following points in time:

See Automount and Domain for more information.

Support for displaying options and their settings via the command line
Use the query options command to display all or part of your options and their current settings. This command accepts an argument to specify a subset of options. The default is to display all options. See Query Options for more information.

Support for gathering Tivoli Storage Manager system information
Use the query systeminfo command to gather information on one or more of the following items and output this information to a file name that you specify:

See Query Systeminfo for more information.

Enhancements for the query filespace command
The query filespace command is enhanced to allow you to query a single file space on the Tivoli Storage Manager server. See Query Filespace for more information.

Separately installable language packs available
Language packs are separately installable packages that contain only language-specific files (such as message catalog, resource file, help files, etc.). You can now install these additional language packs on top of your Tivoli Storage Manager client base install. To change your language preferences, specify the LANG environment variable or use the Preferences editor.

Technical changes for version 5.1.5 - September 2002

The following changes have been made to the product for this edition:

Lan-free data movement support on Linux86 client
Tivoli Storage Manager supports LAN-Free data movement in a storage area network (SAN) environment for the Linux86 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.

New backup-archive option to preserve last access date of files
For backup and archive operations, you can use the preservelastaccessdate option to specify whether the client should reset the last access dates of backed up or archived files to their original value. The default behavior is to not reset the last access date. See Preservelastaccessdate for more information.

Linux86 client support for the General Parallel File System (GPFS)
Tivoli Storage Manager supports backup and restore of the General Parallel File System (GPFS) on the Linux86 client. See Incremental for more information.

Enhanced domain processing
Domain processing is enhanced to allow you to include and exclude items from the domain. Previous versions of Storage Manager only allowed you to include items in the domain. See Domain for more information.

64-Bit support for the Tivoli Storage Manager HP-UX client
The Tivoli Storage Manager 32-bit HP-UX client can perform backup, restore, archive, and retrieve functions to a Tivoli Storage Manager 64-bit server via the Shared Memory communication method.

Support for a globally unique identifier (GUID)
The globally unique identifier (GUID) associates a client node with a host system. When you install the Tivoli software, the tivguid program is run to generate a GUID which is stored in the /etc/tivoli directory on a UNIX system. The GUID for a client node on the server can change if the host system machine is corrupted, if the file entry is lost, or if a user uses the same node name from different host systems. You can perform the following functions from the command line: See Associating your client node with a host system (optional) for more information.

Enhanced query backup and query archive commands
If you use the detail option with the query archive or query backup commands, the client displays the following additional information:

See Query Archive and Query Backup for more information.


Technical changes for version 5.1 - April 2002

The following changes have been made to the product for this edition:

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
Through support of Network Data Management Protocol (NDMP), Tivoli Storage Manager Windows NT, 2000, XP, AIX, and Solaris servers can efficiently back up and restore network attached storage (NAS) file system images to tape drives or libraries that are locally attached to the NAS file servers from Network Appliance. NDMP support is available only on IBM Tivoli Storage Manager Extended Edition. See NDMP support requirements (Extended Edition only) for NDMP support requirements. See 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.

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 snapshot image backup of file systems and raw logical volumes on Linux86 Client
The traditional image backup prevents access to the volume by other system applications during the operation. For Linux86 only: Tivoli Storage Manager can perform an snapshot 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 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 option preschedulecmd 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.
