To reconstitute a ghosted file for use, a single ghosting filter on a
computing device locates ghosting information in the metadata of the
ghosted file and locates within the ghosting information an
identification of a particular ghosting manager of the computing device,
where the identified ghosting manager is responsible for the ghosted
file. Thereafter, the ghosting filter communicates to the identified
ghosting manager a request to obtain data of the ghosted file from a
corresponding alternate location, and the identified ghosting manager
does in fact obtain such requested data from such alternate location.
Upon receiving the requested data of the ghosted file from the identified
ghosting manager, then, the ghosting filter reconstitutes the received
data to the ghosted file. The single ghosting filter is generic to all of
the ghosting managers of the computing device.
