Still another example might be to archive files to a certain disk after a particular project wraps up. Policies can also be used to direct data movement after storage system changes or upgrades. For example, an upgrade policy might direct the storage system to save a copy of your data to a temporary location, replace the tape or disk system with another device, then move the temporary data back to the new storage systems. Finally, some policies may assist with random tape or disk testing to verify that data is being properly archived and is retrievable.

This ensures that an organization can track data from creation through archiving, movement and destruction.
