Abstract
File system independent techniques and mechanisms for replicating files on multiple devices are provided, migrating files from one device to another (for purposes of reliability, increased bandwidth, load balancing, capacity expansion, or reduced cost), and propagating updates from a master copy to remote replicas. The mechanisms involve work queues and asynchronous file migration daemons that operate independently from and in parallel with the primary client-server and network protocol to on-disk storage data paths.
