  • Virtualization of file input/output operations
    Patent number: 9262433
    Abstract: Various embodiments of a system and method for providing input/output virtualization for a file are disclosed. The system may include a filter program that intercepts a write request for a particular file and stores change information specifying the data and the write location indicated by the write request. However, the file itself is not modified. The filter program may also intercept a read request referencing the file and determine whether change information representing a write request to write data at the location specified by the read request has been previously stored. If so then the data specified by the change information is returned in response to the read request.
