Backup and restore - remote backup options

Tried this article by the book and the second server is telling the primary server to backup just fine and the primary server is backing up locally with no prob.

The problem is that the secondary server isn’t restoring. Yes I’ve clicked restore to this server on the secondary server and yes I’ve exchanged keys. The first server wouldn’t be backing up at all if I hadn’t exchanged ssh keys…

I’m running freepbx 2.9.0beta2.3 on both servers. Exact same config.
