I think it is normal. SSH client attempts to verify keys using DNS. See
VerifyHostKeyDNS in the man ssh_config .

Here is the problem, it can't authenticate.
Permission denied (publickey).
But it's a bit confusing because as I understand the server connect to himself
when it try to backup the localhost so when the connection can't be set up ?

Why do you need ssh to backup localhost in the first place? You can connect
directly to rsyncd.
