Abstract
Data partitioned onto two or more storage devices is presented to a user as if the data resided on a single storage area. Data is divided between the storage areas based on policies. Data on the primary storage can utilize frequent back up or other storage management to ensure the accuracy of the data. The data on the secondary storage can employ other data management than the data management for the primary storage. The subdirectory structure is replicated in each area so a data file can be located in either physical area. This allows data files to migrate between the storage areas based on policy.
