Abstract
A volume insight architecture in which software processes internal to the server system issue read/right commands against client data stored on a disk device local to the server independent of client control. A volume insight driver interments the physical location of client data on the server disk and dynamically adjusts the data addresses from the software processes such that they coincide with the actual address of the client data on the server disk. The software processes and the address translation process are invisible to the client. The server treats the locally stored client file system as a local server file system. Processes which can be run against the local file system image on the server cannot distinguish between a true locally mounted file system image and the locally presented file system image presented by the volume insight architecture. Maintenance functions, such as backup, virus detection, etc., are locally performed. This reduces the overhead burden on the client systems.
