Hi Welloki,
Thank you very much for your help! I finally managed to do it :) effectively
I was missing the "sudo rdiff-backup ...." statement in the
ssh/authorized_keys now everything goes fantastic.
As well I found a tutorial it helped me to clarify me a bit more, I leave
the link here in case someone needs it:

Thanks again Weloki, happy backup :)
