search for: transfar

Hi @all! Sorry about that many questions, but after searching and reading tons different web sites, I didn't find exactly what I am searching for. So, I know that with the -z Option rsync compresses the files with gzip, than the files are transfared and at the target machine uncompressed. I want to know, is there a possibility to see how big the compressed file is, which rsync generates before being transfered? If not, is there a chance to let the file compressed on the target machine? I want to make some tests, also with the compression rat...
