Is it possible to use rsync to copy files in one direction only? For example suppose we have :
where the files are initially identical. If one then modifies right/a.txt, then :
rsync -avv left/ right/
will copy right/a.txt onto left/a.txt. Is it possible to restrict rsync to only copying from left/ to right/ (i.e. prevent if from being able to copy from right/ to left/)?
