Tivoli Storage Manager for Windows Using the Backup-Archive Client


Chapter 1. Introducing the Backup-Archive Client

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 tasks:

Migrating from Earlier Versions

Terminology Changes

Previous versions of this product were known as ADSTAR Distributed Storage Manager (ADSM). ADSM is now known as Tivoli Storage Manager. Other terminology changes within this book are as follows:

Previously Known As Now Known As
ADSM backup-archive client Tivoli Storage Manager client, backup-archive client, or client
ADSM backup-archive Web client or Web client Tivoli Storage Manager Web client or Web client
ADSM HSM Tivoli Space Manager or HSM client
ADSM server Tivoli Storage Manager server or server

Changes to Client-Server Communications

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".

Upgrade Path for Clients and Servers

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:

Migrating to the Unicode-Enabled Client

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.

Benefits of Using the Unicode-Enabled Client

How to Migrate to the Unicode-Enabled Client

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.

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:

Considerations for Migrating to the Unicode-Enabled Client

When migrating to the Tivoli Storage Manager Windows NT, 2000 client, please consider the following:

  1. To support Unicode functionality, Windows NT, 2000 clients must connect to a Version 4.2 server. See Tivoli Storage Manager Installing the Clients, SH26-4119, for further environment and installation information.
  2. Ensure that you install the fonts for the languages you want to display. If you do not have the necessary fonts installed, the file names and archive descriptions may not display properly. However, the Windows NT, 2000 client can still back up, restore, archive, and retrieve the files and directories.
  3. The Unicode-enabled version of a renamed file space name may be unreadable if the server cannot display the Unicode name. In this case, use the file space identifier (fsID) of the file space to identify these file spaces on the server. Use the query filespace command with the detail option to display the fsID of a file space. The file information dialog in the native and Web client GUIs also displays the fsID.
  4. After installing the V.4.2 Windows NT, 2000 client, we recommend that you perform a full incremental backup to rename all existing file spaces that are not Unicode enabled and back up the files and directories within them under the new Unicode-enabled file spaces.
  5. Renamed file spaces remain on the server and managed as stabilized file spaces. These file spaces contain all the original data, which can still be restored until the file spaces are deleted. You can find additional information in the Tivoli Storage Manager for Windows Administrator's Guide.
  6. The server stores information about each node, and once a node logs onto the server using a Windows NT, 2000 client, it cannot log on with a client that does not support Unicode. The server allows only a Windows NT, 2000 client to restore files from a Unicode-enabled file space.
  7. When backing up files to a file space that is not Unicode enabled, the Windows NT, 2000 client skips the files and directories with names containing characters from a code page other than the current locale.
  8. If files and directories with names containing characters from a code page other than the current locale were previously backed up with a client that was not Unicode enabled, Tivoli Storage Manager will expire them in the file space that is not Unicode enabled. However, the Windows NT, 2000 client can back up or archive these files to a Unicode-enabled file space.
  9. When migrating from a client that is not Unicode enabled to a Unicode Client, filenames with double-byte characters mixed with single-byte characters may be restored in mixed single-byte character set (SBCS) format. This is only a display issue.
  10. When a client performs a selective backup of an object and the original file space is renamed, the new Unicode-enabled file space contains only that object. Tivoli Storage Manager will back up all other directories and file spaces during the next full incremental backup.

Tivoli Data Protection for NDMP Version 4.2.1 Requirements

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:

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.

Additional Migration Information

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.


Using Storage Management Policies

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.


Setting Processing Options

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".


Backing Up and Restoring Files

Note:
Unless otherwise specified, references in this manual to Windows 98 also include Windows Me (Millennium Edition). References to Windows NT also include Windows 2000.

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.

Note:
For Windows 2000: Tivoli Storage Manager will back up a sparse file as a regular file if the compression option is turned off. To minimize network transaction time and maximize server storage space, enable file compression when backing up sparse files. For more information about backing up and restoring sparse files, see Chapter 3, Backing Up and Restoring.

Archiving and Retrieving Files

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.


Using the Web Backup-Archive Client

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.


Automating Tasks

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.
