Abstract

See full text

A system that places a statistical collection routine, which tracks file usage, within the path lookup process of an operating system. A statistic summarization process runs as a task of the operating system and periodically accesses the statistics collected by the statistics collection routine and updates a database. A file migration process is scheduled to run periodically to examine the database information. Files that have a predetermined usage during the time may be migrated, based on user criteria, between a primary, high speed, storage device and a secondary, slow speed, storage device. The secondary storage device might be a network file server attached to a local area network, a read-only device, or other storage device.
