had a quick read of the web site, just wondering how effective it would
be with something like rdiff-backup - my line of thinking is that rd
stores the differences, so I would guess all the original files would
benefit, but the differences wouldn't
Also with fusecompress you can specify by mime type which files pass
through ie don't get affected by fusecompress.
I will have to investigate a bit more, run some tests
