Method and apparatus for client sided backup and redundancy

摘要

A file request is received by the operating system, and the appropriate IFS driver for the file is called. The IFS driver remaps the drive path based on a drive location list contained in a file redirection table in the IFS driver. Drive or server redundancy is ensured by simultaneously broadcasting writes to each drive on the drive location list. Redundancy is ensured for read operations by sequentially traversing the drive location list in the event of a non-responsive drive or server.
