Abstract
In at least one embodiment of the invention, a primary storage facility is managed in an HSM system. Data is relocated from the primary storage facility to a secondary storage facility. A request is received from a client for only a portion of the relocated data. In response to the request, the requested portion of the data is obtained from the secondary storage facility and stored in the primary storage facility as a sparse file. The requested portion of the data is then provided to the client from the sparse file.
