The TSM backup-archive client helps you protect information on your workstation. Using TSM, you can maintain backup versions of your workstation files that you can restore quickly and easily 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 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 TSM
tasks:
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
identified in the table below.
Previously Known As | Now Known As |
ADSM backup-archive client | TSM backup-archive client or backup-archive client |
ADSM backup-archive Web client or Web client | TSM backup-archive Web client, Web client or Enterprise Management Web client |
ADSM HSM | Tivoli Space Manager or HSM client |
ADSM AFS/DFS backup clients | TSM AFS/DFS backup clients |
ADSM server | TSM server, Tivoli ADSM server or server |
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 all client platforms except Macintosh and NetWare. Version 3.7 does not include a native GUI administrative interface. Version 3.1 for Windows 95, Windows 98 and Windows NT included a native GUI administrative interface that can be used with Version 3.7. The primary intended interface to the server is the Web administrative interface and requires a Web browser. The Web administrative interface has enhanced functionality such as server-to-server communication, more device classes, and enhanced libraries and drives compared to the Version 3.1 administrative interface. The Web administrative interface is packaged and installed with the server.
TSM Version 3.7 clients restore or retrieve backup or archive data from previous Version 3 clients. However, previous Version 3 clients cannot access a Version 3.7 client's backup or archive data, regardless of the TSM server version. This is because Version 3.7 backup-archive clients store files with different attributes than previous version clients. After installing a Version 3.7 client, TSM may update the attributes only (not data) for active Version 3 files on the TSM server during the first incremental backup.
In addition, previous Version 3.7 clients cannot access backup or archive data from Version 3.7.2 clients because Version 3.7.2 backup-archive clients store files with different attributes than previous version clients.
Version 3.7 clients can perform backup, archive, restore, and retrieve functions with a Version 2 OS/2 server or a Version 3.1 ADSM server. However, many client features added with Version 3.7 are only available when using a TSM Version 3.7 server.
You cannot use the Version 3.7 TSM Web backup-archive client with a Version 2 server.
Storage management policies are a set of rules that 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 the storage management policy you use for a group of files specifies that they can be backed up only once a week, your administrator can schedule automatic backup services to occur for those files on a particular day each week.
For more information about storage management policies, see Chapter 6, Understanding Storage Management Policies.
TSM 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, and are in effect for an entire session.
Setting Options in a Client Options File- During initial installation and setup, TSM 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 Preference 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.
There are four types of backup:
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.
For more information about backing up and restoring, see Chapter 3, Backing Up and Restoring Files.
You request archive services when you want to save files at a specific point, or when you want to place copies of files on 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 or a group of files, or all files in a directory.
When you archive a file, you can 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 machine, or platform that supports a Java 1.1.6-capable browser, 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. Do not perform such actions simultaneously on the same browser, or you may unintentionally destroy data that you need. The Web client is available on the following client platforms:
The Web client is supported only on a server that is Version 3 or higher.
The following functions are not supported by the Web client:
See "Starting A Web Client Session" for information about starting and using the Web client.
TSM 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 the desired 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. For more information about scheduling, see Chapter 5, Automating TSM Tasks.
