7.1.1 Defining policy domains The sample configuration consists of two policy domains: for servers and for workstations, respectively. The typical nature of the data found on each type of machine makes this a logical division of resources and follows the administrative boundaries used by many customers. Example 7-1 defines these policy domains, using the define policy command. Example 7-1 Recommended policy domains tsm: ATLANTIC>define domain server description="Server Nodes" backretention=100 archretention=365 ANR1500I Policy domain SERVER defined. tsm: ATLANTIC>define domain workstn description="Workstation Nodes" backretention=30 archretention=100 ANR1500I Policy domain WORKSTN defined. 7.1.2 Defining policy sets We recommend defining one policy set for each of the policy domains, as shown in Example 7-2. We use the define policyset command. Example 7-2 Defining a policy set per domain tsm: ATLANTIC>def policyset server server description="Policy Set for Server Nodes" ANR1510I Policy set SERVER defined in policy domain SERVER. tsm: ATLANTIC>def policyset server workstn description="Policy Set for Workstation Nodes" ANR1510I Policy set WORKSTN defined in policy domain SERVER. 7.1.3 Defining management classes We have defined four management classes for each domain in the sample configuration. These management classes are used to categorize the domain data: DATA: This is the default management class for each domain. It is used for most of the data in the environment. DIRECTORY: Directory objects are assigned to this class. Binding directories to a special management class allows us to properly set their expiration rules and control their final storage repository. SPECIAL: This management class is used to store files that are being modified during backup. An application log file could be bound to this 272 IBM Tivoli Storage Manager Implementation Guide
