A system, method and computer program product that manage storage device load, including (a) classifying processes that access a storage device as high priority and low priority; (b) monitoring access activity to the storage device by the high priority processes; and (c) regulating the access activity of the low priority processes based on the access activity of the high priority processes. A counter can be used to monitor the access activity of the high priority processes, so that a request to the storage device increases the counter and a response from the storage device decreases the counter, and access to the storage device for the low priority processes when the counter is zero. The low priority processes can be backup processes, security system processes, anti-virus processes, compression processes, archive systems, and applications that monitor storage device access.
