Do you have an idea how i can use it for compressing a whole file?
Is there a de/compress (char *file) function?

You are right - an internal compression to rsync would be nice. But i would
also suggest having a userdefinable option for the compressing program. I
prefer lzo (http://www.oberhumer.com/opensource/lzo/). The compressor depends
on the files you are using, e.g. bzip2 is good for small textfiles - lzo is
fast and can be used for large database files where there are changes every
3-4 days.
