How can I automate backup using SFTP on cluster nodes?

Hi!   I´m trying to automate backup to a remote host using SFTP.  I´ve generated keys uysing ssh-keygen and it works from one node. Now, I want to do the same from the second host of the HA clust...

    I have understood how it works. I thought that I had to put the private key file name in the textbox "Copy/Paste the SSH private key to be used for passwordless authentication:"

    But, I have to put the content of the private key. So there´s no need to copy private keys between nodes.

    Now, it works fine!.

    Thanks.

you just need to add the same public key generated by ssh-keygen, not the private key, to user's ~/.ssh/authorized_keys file in second and subsequent SSH servers.

But, your solution would be to sftp from f5-node1 to f5-node2, wouldn´t it? 

I f I want to sftp from f5-node1 to SFTP server and f5-node2 to SFTP server I think that your solution isn`t valid. Am I wrong?
