diff -qr command between local and remote directories

According to this process substitution can be used to do a SIMPLE diff between local and remote machine. However, I want to use the -qr option in the diff command, i.e., it must be recursive and brief (reports only files that differ). If I try to do

`
diff -qr <(ls -R ~/Documents) <(ssh myusername@192.168.1.150 ls -R /pathinmyremote/My_remote_Documents)

` I get Files /dev/fd/63 and /dev/fd/62 differ which is obviously not what I am looking for. There are suggestions of using rsync with the dry-run option, but that does not include the brief option. The reason for -qr is that I want to know 1) which files are in my local machine and missing in my remote backup, and 2) which files that have been changed/updated in my local machine with respect to the ones in the backup remote. **Update** The suggestion to use rsync -n -ai --delete ~/Documents myusername@192.168.1.150:/pathinmyremote/My_remote_Documents results in:

which is also not right (due to the existing files/directories)
