Package: rsync 3.1.1-4
Architecture: x86_64 GNU/Linux
What it isn't doing:
When trying to sync two mounted identical structured folders on two hosts using
rsync -vhtru "/path/folder" "firstname.lastname@example.org:/path/"
works as expected but
rsync -vhtru "/path/folder/" "email@example.com:/path/folder"
dump copies everything - even with -u and --size-only given!
What it should be doing:
According to man pages
rsync -av /src/foo /dest
rsync -av /src/foo/ /dest/foo
should do the same
I know of no such bug. I would suggest that you use the options --dry-run (-n) along with --itemize (-i) to see what is going on in your copying (e.g. if everything is copied as new files due to a path mismatch). Also, feel free to ask questions on the mailing list if you need assistance.
