Patent attributes
Methods and apparatus, including computer program products, for network-extended storage. A portable storage device is coupled to a host computer, and network extension code stored on the portable storage device is invoked. The network extension code is operable to detect a file system write function call generated by an application executing on the host computer, the file system write function call operable to cause data to be written to the portable storage device, and cause the data to be written to the portable storage device based upon the file system write function call. The network extension code is further operable to generate a transmit determination indicative of whether to transmit the data to a network repository, and transmit the data to the network repository based upon the transmit determination.
