From a backup-archive client node, files can be backed up or archived to the server. This process ensures that current data can be restored or retrieved if it is accidentally deleted or corrupted on the workstations. Files from the Tivoli Space Manager client (also known as the HSM client) can also be migrated from local file systems to TSM server storage. Recall of migrated files is transparent and automatic when a client accesses a file, or the client can selectively recall files. Tivoli Data Protection application clients use the server for backup operations.
As the administrator, you define the rules for these operations based on user requirements for backing up, archiving, or migrating data. The rules are called policies. Policy identifies backup, archive, and migration criteria, where the client data is stored, and how the data is managed by the server.
For more information about establishing and managing policies, see Chapter 10, Managing Client Data Using Policies.
