7.4 Enforcing your policy Once the policy is defined, you want to enforce it using the expire inventory command. This command makes sure that any extra copies of data in your copy groups are removed from the database. It also takes care of data that is older than your specified retention period. The backup copy group parameters VEREXISTS, VERDELETED, RETEXTRA, and RETONLY are applied to backup data through the expiration process as well as the archive copy group parameter RETVER. Example 7-13 shows how to expire the database references from the Tivoli Storage Manager server. Example 7-13 Expiring inventory tsm: ATLANTIC> expire inventory ANS8003I Process number 22 started. This command can be computationally intensive; therefore, it should be run during quieter times on the Tivoli Storage Manager server. The EXPINTERVAL parameter in the server options file specifies the number of hours between automatic expiration processing, and is initially configured for 24 hours. With automatic expiration processing enabled, the server runs inventory expiration at start-up and every 24 hours thereafter. We recommend setting the EXPINTERVAL to zero (disabling automatic expiration) and defining a daily administrative schedule to run this command at a convenient time. We show how to do this in 12.2.4, "Defining an expiration schedule" on page 382. 7.5 Summary We expect that you now understand and have configured the policies for your data retention. Next we discuss user management, to provide you with an understanding of administration roles within Tivoli Storage Manager. 282 IBM Tivoli Storage Manager Implementation Guide
