I realise that ~/.ssh/ssh_config is for outgoing SSH connections and ~/.ssh/sshd_config is for incoming connections

I think I understand the idea of the root-equivalent account ?...

You seem to have ignored the "root-equivalent" account, which I've mentioned a few times. That's the key.

Not ignored, just didnt understand.

So I did some further research...

Are you referring to the user and group of the ssh keys ?



The id_rsa and id_rsa.pub key user and group on the Ubuntu server is ubuntuusername:ubuntuusername (in the /home/ubuntuusername/.ssh...

Thanks SeijiSensei, I've done that before with rsync but I don't think it can be done with rdiff-backup ?

Thanks TheFu,

I shall try your fix for RECYCLE.BIN and add the 3 exclusions you mentioned for rdiff-backup.

The script I posted is only a snippet and slightly modified.

The actual script is shown below, so hopefully this resolves your concerns ?
