Dropbear SSH into another Drobo / Passwordless login


I’d like to run a backup rsync job from one Drobo to another. I’ve managed to get rsync and the ssh tools installed so that I can ssh from my desktop into backup@drobo1.local and then ssh into backup@drobo2.local from drobo1.local

What I need to setup is the backup user on Drobo2 which has a passwordless login from Drobo.

How do I go about setting this up?


If you are going to use a passwordless login, then why are you using SSH? You could just use rsync directly, which would have the advantage of being faster as well.

Using SSH with authorized keys is the way…
