From a 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 an HSM client can also be migrated from local file systems to ADSM server storage. Recall of migrated files is transparent and automatic when a client accesses a file, or the client can selectively recall files.
You define the rules for these operations, called policies, based on user requirements for backing up, archiving, or migrating data. 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 12. "Managing Client Data Using Policies".
