Not sure if I have an rsync problem or ssh problem

[robothunter]

I'm trying to use rsync to backup my Synology NAS to my NAS4Free box offsite. I want to begin the process locally because it's so much data. I have everything set up on my NAS4Free box. The problem is setting up rsync on my Synology. More specifically the SSH encryption. If I choose transfer encryption off it works. If I choose transfer encryption on I get an error message "Failed to establish the SSH connection. Please check...." I can log into my NAS4Free box using Putty so I know SSH is working. When I created my user name I set the Shell to sh, I made the primary group wheel and then I added admin and sshd groups for good measure. Any ideas?

Sounds like a Synology issue, yes. They have 5 years of full tech support. Why not ask them? I have no idea what packages they have on that thing, or even what OS it is. It sounds like they just don't have the package installed.

After trying to use Syncthing as an alternative I went back to trying to get rsync to work. I kept tinkering with it and when I set the user to root it started working. I'm happy that rsync is working with encryption but using root to do it just feels wrong. I will continue to tinker.

I finally found a solution to my problem on the Synology forums.

Once I had that rsyncd.conf file in the right place (Step 7) I was good to go. I deviated from his instructions at step 8 because of Synology's new Hyper Backup system. I chose "Remote Data Copy" instead of "Remote rsync Server" because I wanted usable files on the backup server instead of compressed file chunks. Thanks for the suggestion Jack.
