Do you have WSL activated? If so, can you please do two things: First, install the latest developer snapshot from https://cygwin.com/snapshots/. This is essential! Second, check with `lsattr' if all or some of the directories you're trying to rsync have the "case-sensitivity" flag set, e.g. $ lsattr -d foo ---------n-C foo That means the flag is set. Remove the flag recursively, e.g. $ chattr -R -C foo Now try rsync again. Here's what I found two days ago: https://github.com/Microsoft/WSL/issues/3885 The developer snapshot is needed so that Cygwin does not create case-sensitive directories by default. I'd released 3.0.2 with this patch already but I'm still waiting for a report to a certain. problem. HTH, Corinna -- Corinna Vinschen Cygwin Maintainer
