Summary: an xattr filter rule (e.g. --filter='-x! user.*’, which is suggested by the documentation) is treated as a file filter rule on the remote side.
Repro #1, sender is local: host1$ rsync --filter=‘-x! user.*' -avvvHX --delete /tmp/test/. host2:test ... [Receiver] add_rule(-! user.*) Repro #2, sender is remote: host1$ rsync --filter=‘-x! user.*' -avvvHX --delete host2:test/. /tmp/test ... [sender] add_rule(-! user.*) One possible and quite dangerous symptom of this is that the incorrect (-! user.*) rule matches (almost) all remote files, therefore in repro #1, no remote files are deleted, and in repro #2, nothing is transferred and all local files are deleted.
