I'm writing a backup with rsync and a file with the systemd mount unit escape \x2d for - on a cifs (protocol version 3) (/mnt/diskstation/backup in this example) causes the following trouble:

> sudo rsync -a /etc/systemd/system/ /mnt/diskstation/backup/test/
rsync: recv_generator: failed to stat "/mnt/diskstation/backup/test/snap-openmapper\x2ddesktop-22.mount": Invalid argument (22)
rsync: symlink "/mnt/diskstation/backup/test/multi-user.target.wants/snap-openmapper\x2ddesktop-22.mount" -> "/etc/systemd/system/snap-openmapper\x2ddesktop-22.mount" failed: Invalid argument (22)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1196) [sender=3.1.2]

Copying the file to /tmp with sudo rsync -a /etc/systemd/system/ /tmp/test/ works fine.

Some more info about the file:

> stat /etc/systemd/system/snap-openmapper\\x2ddesktop-22.mount

I'm wondering where the responsibility for this behaviour lies: user (cifs might have trouble allowing \ in the name, but it's 2018, so...), rsync or cifs.
