Hello,
Is anyone using HBS 3 to backup to Hetzner’s cloud with RSYNC?
I just can’t get that to work. 
I am discussing this with QNAP support, but a solution has been waiting for almost 2 years. I think HBS 3 is the problem, because I can use RSYNC to make a backup from the CLI of my QNAP to the Hetzner cloud.
QNAP/HBS is working on a solution and I am in contact with support about it.
It is possible, because on Hetzner’s website there is a description of how to make backups from a Synology (Synology Hyper Backup to Hetzner Storage Box) to Hetzner’s cloud.
A year ago there was already an announcement that the bug would be fixed in the next release, but unfortunately it was delayed again and again and still hasn’t been fixed. 
Today I received the message that the next release is not until June. 
Also see this topic on HBS 3 backup to Hetzner-cloud with RSYNC - QNAP NAS Community Forum (Shutting Down Soon) ( Because this forum is to be closed, I started the discussion here again)
Thoughts on this???
Regards,
