A data storage management and scheduling system schedules the recording, storing, and deleting of television and Web page program material on a client system storage medium. A schedule of time versus available storage space is generated that is optimal for the viewer's scheduled program recordings. The programs include television broadcast programs and Universal Resource Locators (URLs). A program is recorded if at all times between when the recording would be initiated and when it expires, sufficient space is available to hold it. All scheduling conflicts are resolved as early as possible.
