It is critical to control access to backup images that are stored in TSM when running multiple Teradata backup jobs. Stored data often contains sensitive information (such as financial material) that requires restricted access. Limit access to particular subsets of Teradata backups by creating additional TSM client nodes that correspond to each security domain to be established.
In the same way that defining pseudo nodes in the TSM catalog is recommended for all Teradata backups, pseudo nodes for each major security domain can also be created. Use these TSM server administration console commands, for example, to segregate financial data backups from other data warehouse backups:
Register node EDW001 EDW_PASSWORD Register node EDW_FINANCE FINANCE_PASSWORD
Choosing this option requires creating special copies of the Default and Client Options files to store the passwords in restricted files. Set these restrictions in Windows.
