The Tivoli Storage Manager backup-archive client helps you protect information on your workstation. Using Tivoli Storage Manager, you can maintain backup versions of your workstation files that you can restore if the original files are damaged or lost. You can also archive workstation files that you do not currently need, or preserve them in their current state, and retrieve them when necessary.
You can use the graphical user interface, commands, or the Web client to perform tasks. The command line client is also useful if you run client commands in batch mode.
As a quick reference, the following could be considered primary

Tivoli Storage Manager no longer supports the NETBIOS communication method. Therefore, the Windows NT and Windows 2000 clients no longer support the following options:
Tivoli Storage Manager no longer supports the SNA LU6.2 (APPC) communication method for the Windows clients. Therefore, these clients no longer support the following options:
We recommend TCP/IP as the replacement communication method for former NETBIOS and SNA LU6.2 (APPC) users of the Windows clients.
For more information about the communication methods supported for your Tivoli Storage Manager client, see "Communication Options".
As part of a migration plan from Tivoli Storage Manager Version 4.1 to Tivoli Storage Manager Version 4.2, clients and servers may be upgraded at different times. To ensure that you can continue your backup and archive activities during the migration, please note the following:
Unicode is a universal character encoding standard that supports the interchange, processing, and display of text that is written in any of the languages of the modern world. Unicode-enabled file spaces provide support for multi-lingual workstations without regard for the current locale. Beginning with Tivoli Storage Manager Version 4.2, the Windows NT and Windows 2000 clients are Unicode enabled. Windows NT and Windows 2000 clients support the Unicode code page for file, directory, and file space names. See Tivoli Storage Manager Installing the Clients, SH26-4119 for a list of supported language environments. Unicode is not supported on Windows 98 and Windows Me clients because their respective operating systems do not support Unicode.
To migrate to the Windows NT, 2000 V.4.2 client, the server must be a Version 4.2.0 level server. New clients storing data on the server for the first time require no special set up. In this case, the server automatically stores data in Unicode-enabled file spaces. However, if your client already stores data on the server, you need to plan for the migration of your file spaces to Unicode-enabled file spaces. This involves renaming your file spaces on the server and creating new Unicode-enabled file spaces on the server using the autofsrename option. For detailed information about this option, see Autofsrename.
The administrator can specify three possible values using the server autofsrename option: yes, no, or client. Note that the server setting for this option overrides the setting on the client.
If the client performs a selective backup, only the file spaces you specify in the current operation are renamed and Unicode enabled.
Optionally, your administrator can rename the file spaces on the server that are not Unicode enabled.
For options and results when using the autofsrename option, see
the table below.
Server Option | Client Option | Result |
---|---|---|
Yes | Prompt, Yes, No | Renamed |
No | Prompt, Yes, No | Not Renamed |
Client | No | Not Renamed |
Client | Yes | Renamed |
Client | Prompt | Based on User Response |
For detailed information about the autofsrename option, see Autofsrename. For additional migration information, see Tivoli Storage Manager for Windows Administrator's Guide. For additional information about working with the Windows NT, 2000 client, see:
When migrating to the Tivoli Storage Manager Windows NT, 2000 client, please consider the following:
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. Tivoli Data Protection for NDMP enables backup and restore support on the Tivoli Storage Manager Windows NT and Windows 2000 servers for NAS file servers from Network Appliance. Tivoli Data Protection for NDMP is a separately priced and licensed product.
Tivoli Data Protection for NDMP requires the following hardware and software:
www.tivoli.com/storage
www.tivoli.com/storage
See Appendix A, "Backing Up NAS File Systems" for further information, including how to back up and restore NAS file system images using the Web client and command line client.
When you install the Web client, you must install the client for the language you want to use.
A command line administrative client is available on client platforms. The primary intended interface to the server is the Web administrative interface and requires a Web browser. The Web administrative interface is packaged and installed with the server.
Storage management policies govern how and when your data is backed up and archived. Your administrator defines these policies, and you associate them with your data.
Your administrator can coordinate scheduled services with the storage management policies you use for your files. For example, if your storage management policy for a group of files requires that they are backed up once a week, your administrator can schedule automatic backup services for those files on a particular day each week.
For more information about storage management policies, see Chapter 6, Understanding Storage Management Policies.
Tivoli Storage Manager includes options that control processing for user sessions. For example, you can use options to specify what communications methods to use, or to restrict or permit access to your data. These options reside in the client options file (dsm.opt) and are in effect for an entire session.
Setting Options in a Client Options File - During initial installation and setup, Tivoli Storage Manager provides a sample client options file. If you want to use different options, copy the sample client options file and modify the new copy. You can perform these same tasks using the Preferences Editor or Setup Wizard on the GUI. See "Creating and Modifying a Client Options File" for more information.
In addition, you can override an option in the client options file by entering a different value for the option with an appropriate command. See "Entering Options with a Command" for more information.
Creating an Include-Exclude List - You can create an include-exclude list in your client options file to include or exclude specific files, directories (or both) from backup or encryption services. See Chapter 7, "Creating an Include-Exclude List" for more information.
For detailed information about individual options, see "Client Options Reference".
You request backup services when you want to save copies of files that you can restore if the original files are lost or damaged. These copies are called backup versions or backups.
You can perform the following types of backups:
Tivoli Storage Manager provides backup and archive services for all files on the following systems:
You can restore a single file, a group of files, or all files in a directory. You can restore files to the same directory from which you backed them up or to a different directory. You can restore any files you back up and any other files to which another user grants you access.
You request archive services when you want to save files at a specific point, or place copies in long-term storage and erase them from your workstation. These copies are called archive copies or archives. Archives are never replaced with more current versions, but are preserved exactly as you store them.
You can archive a single file or a group of files, or all files in a directory.
When you archive a file, enter a description of the file that you can use later to retrieve it from storage to your workstation. You can return an archived file to the same directory from which you archived it, or to a different directory. You can retrieve any files you archive and any other files to which another user grants you access.
For more information about archiving and retrieving, see Chapter 4, Archiving and Retrieving Files.
The Web backup-archive client (Web client) permits an authorized administrator, help desk person, or end user to perform backup, restore, archive, and retrieve services on any workstation or platform that supports a Java 1.1.6-capable browser. This includes browsers such as Netscape Navigator 4.06 or higher or Microsoft Internet Explorer 4.01 or higher. You can perform multiple Web client sessions simultaneously. For example, you can perform a backup, archive, restore, and query on separate Web browsers. The Web client is available on the Windows 98, Me, 2000, and NT 4.0 client platforms.
Only a server that is Version 3 or higher supports the Web client.
The Web client does not support the following functions:
See "Starting a Web Client Session" for information about starting and using the Web client.
Tivoli Storage Manager provides central scheduling to automatically perform tasks. Your administrator defines schedules. For example, you might have files that you want backed up daily, weekly, or monthly. After defining your schedules, your administrator associates your client node with those schedules. Then, when you run the client scheduler, it tells the server to include your node when running the appropriate schedule. You can also define schedules remotely for networked nodes. For more information about scheduling, see Chapter 5, Automating Tasks.
