It requires at leadt few bytes, there is no way to represent 10GB of data in 8 bits.

  But of course there is. Imagine the following compression scheme: 0-253: output the input byte 254 followed by 0: output 254 254 followed by 1: output 255 255: output 10GB of zeroes Of course this is an artificial example, but theoretically it's perfectly sound. In fact, I think you could get there with static huffman trees supported by some formats, including gzip.

    What you suggest is saving the information somewhere else and putting a number to represent it. That is not compression, that is mapping. By using this logic, one can argue that one bit is enough as well.

    > 254 followed by 0: output 254 126, surely?
