I think what is unique here could be the "on-the-fly, transparent". But this kind of compression can be better achieved I think with one core of your CPU, plaintext compression of 3x shouldn't need lzma (and if you really need to compress 22TB of plain text with no binary or multimedia files, well maybe you could compress it slightly with lz4 or a simple zlib compression before sending it).
