Schemes to limit client activity are contrary to the overall purpose of TSM, where denying a department the ability to safeguard its data can result in losses which would be painful to the organization.
But, TSM server administrators do have to deal with "pests" at various times. Where "social engineering" does not work, and measures are sanctioned to safeguard TSM service to the community as a whole, more draconian measures can be pursued. By various means (e.g., accounting records monitoring), client activity can be gauged and quelled by measures such as setting MAXNUMMP to 0, which stops backup/archive tape use but allows needed restore/retrieve. A real nuisance deserves a LOCK Node for some period of time. Richard Sims at Boston University
