Don't compress files (just copy them) that are known to be badly compressible

Hi everybody.

File types that are already compressed (zip, zipx, rar, bz2, cab, gz, gze, lha, lzh, docx, odg, odp, ods, odt, pdf, ott, pptx, xlsx, avi, mkv, mpg, mpg, mp4, gif, png, jpeg, ogg, aac, flac, mp3, wma, etc...) should not be compressed again but instead just copied.

It would be VERY useful (and way faster compressed backup archives creation) don't compress these files (but still add them to compressed backup archive).

It would be possible (or is it a 7zip limitation? With some zip/gzip based backup programs is possible)?

Many thanks
