Hello Hendrik and thanks for your reply.

I have to say that on a similar setup, I'm succeeding with the command I
told you before.

I think I have to go a bit deeper in details: I'm using BackupPC and
this piece of software connects remotely to Synology NAS with ssh and
It works as follows:
1) SSH tunnel gets opened by:

/var/lib/backuppc/ -fC root at synology.remote -L
8881: sleep 60

where contains:

ssh $@ 1>/dev/null 2>/dev/null && echo "SSH started successfully."

2) rsync starts to transfer files within the SSH tunnel.

Where may I need to look for configuration or permission errors?
The differences between the two Synology NAS, besides the hardware ones,
are their firmware versions. Still, the rsync is the same version:
"3.0.4 protocol version 30".

Any other thing?

Kind regards,
Flavio Boniforti
