Provided is a system and method for storing electronic data that does not depend on a format specific to a storage device.The system receives data to be stored from a back-up server, compresses and encrypts it, and creates a virtual file. An encryption key and 'meta-data', which includes information about the physical attributes of electronic data in the virtual file, are also created by the system. The virtual file, with meta-data, can then be held at a storage device without specifically formatting the virtual file for the device. The encryption key is held separately for subsequent use in file reconstruction.

A recording apparatus for copying a digital stream recorded on a first recording medium using a code format compatible with the first recording medium to a second recording medium after the digital stream has been converted to a code format compatible with the second recording medium, comprising: a detection unit operable to detect a plurality of devices that are available for distributed processing from devices connected to the recording apparatus via a network; an allocation unit operable to divide the digital stream at one or more predetermined points on a playback time axis and to allocate the divided portions to the detected devices respectively; a transmission unit operable to transmit the allocated portions to the respective detected devices; a control unit operable to control the detected devices to perform transcoding for converting a code format of the allocated portions to the code format compatible with the second recording device; and a writing unit operable to receive converted portions resulting from the transcoding from the detected devices and to write the received portions to the second recording medium.
