How to back up one EX2 to another?

I have two 8T EX2s, running without RAID. No RAID because the play is to back up to one of them, and then back that up to the other one. But I haven’t been able to get the cross-backup configured. When I try to browse to the destination folder, I get this error:

Remote Backup cannot proceed due to an SSH access failure

Remote Backup cannot proceed due to a failed RSYNC Test

(The two choices for what kind of device are NAS or WD Cloud. I certainly don’t want WD Cloud, because then it would try to push 8T upstream on a DSL line. I want to run over our local gigabit network to another EX2 NAS.)

UPDATE: Well, I’ve semi-answered my question. I think I need to do this:

You have added port forwarding rules for both SSH and Remote Backup services in Settings > Network > Port Forwarding in order to see your WD My Cloud EX2 device over the internet.

So I tried that, for both SSH and Remote Backup, and they both say “Failed”.

Also, I don’t see where to set the SSH password, which the backups dialog says I have to enter.

It would be great if there was a step-by-step explanation of how to do this.

Okay, got it. Lots of fumbling around and experimenting, but the gist of it is:

Settings -> Network page

Turn on Remote Server

Under Port Forwarding, click Add

Select scan

Click SSH and Remote Backups

Click okay

Click Configure next to SSH on network settings page

Enter a password and remember what you entered

Click Configure next to Remote Server

Enter a password and remember what you entered

Try creating a backup

Hi jshowalter and welcome to the forum. Glad to see that you figured it out.

It would be nice to know if the backup succeeded and other details like size of backup, time needed, etc
