7 Chapter7. Data storage policies In this chapter we focus on the actual storage policy implementation. Before continuing, you should have already filled out the planning sheets, and we assume that you have read and understood the IBM Tivoli Storage Management Concepts, SG24-4877. We have now covered planning through installation and customizing your storage devices. Now we cover how to set up your storage policies. A data storage environment consists of three types of resources: machines, rules, and data. The machines are computers containing data that must be backed up, and the rules specify how the backup copies are to be treated. Depending on how you need to manage your backup data, your data storage policy can be very simple or very complex. The simplest policy would have one set of rules that apply to all of the data in your organization, while the most complex policy would be to have a unique set of rules for each individual file. Most installations fall somewhere between these two extremes. IBM Tivoli Storage Manager has entities that group and organize the resources and define relationships between them. A client, also known as a node in IBM Tivoli Storage Manager terminology, is grouped together with other nodes into a policy domain. The domain links the nodes to a policy set, which consists of management classes. A management class contains rules called copy groups that it links to the data. When the data is linked to particular rules, it is said to be bound to the management class that contains the rules. © Copyright IBM Corp. 1999, 2000, 2003, 2006. All rights reserved. 269
