A remote storage digital video recorder (RSDVR) retains multiple copies of media programs so long as the copies are expected to be useful to at least one user. Rather than assigning copies to specific users at the time the program is recorded, copies can be assigned as the users request access to the particular media programs. Copies of unassigned programs can be deleted according to a schedule to reduce disk storage and processing demands on the system. A pool of program copies that are not initially assigned to particular users can be maintained until the user makes a specific request to view the program. This “late assignment” of program copies can substantially reduce the amount of data stored by the RSDVR system without substantially impacting the viewer experience.
