IBM Tivoli Storage Manager for UNIX: Backup-Archive Clients Installation and User's Guide
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.
|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:
|
- |Backup-archive Native Graphical User Interface (Motif GUI).
- |LAN-free data transfer.
- |Cluster support.
|
|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.
|
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:
- When Tivoli Storage Manager client starts
- When the back up is started
- When the Tivoli Storage Manager client has reached an automounted file
system during backup
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:
- DSMOPTFILE - The contents of dsm.opt file.
- ENV - Environment variables.
- ERRORLOG - The Tivoli Storage Manager error log file.
- FILE - Attributes for the file name that you specify.
- INCLEXCL - Compiles a list of include-exclude in the order in which they
are processed during backup and archive operations.
- OPTIONS - Compiled options.
- OSINFO - Name and version of the client operating system (includes ULIMIT
information for UNIX).
- POLICY - Policy set dump.
- DSMSYSFILE - The contents of the dsm.sys file.
- CLUSTER - AIX cluster information.
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.
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:
- Create a new GUID
- View the current GUID
- Write a specific value
- Create another GUID even if one exists.
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:
- Last modification date
- Last access date
See Query Archive and Query Backup for more information.
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.
