rsync -a /sourcedir/data /destinationdir/backupdata
* this makes two eqauls dirs
but how it is possible to compare something like this:
rsync -a /sourcedir/data /destinationdir/backupdata.gz
* offcourse this command doesn't work. But is it possible somehow to compare content of gzip archive with /sourcedir/data and if differ to update archive, or create new one.
