File server data processing system has data management configured so that data that is accessed relatively infrequently is stored off-server and represented on-server by meta-data , thereby speeding disaster recovery

摘要

Data processing arrangement comprising a data network (10) and a fileserver (12) with integral data storage (16) containing at least a primary file system (18). The files of the file system are arranged in a hierarchy with at least two primary activity groups (22, 24, 26) according to a primary activity criterion. Data from the activity group (26) lowest in the hierarchy is coped to a secondary file system in a data store (36) of a backup unit (42) with the data management unit (20) creating corresponding meta-data in the primary files system.
