I was referring to using rsync for Linux clients, not Windows.  For the 1 
Windows server I archive, I use rsyncd.  I have not even tried rsyncd on 
Linux.

Setting up SSH keys is easy:

On BackupPC server, as root:

ssh-keygen -b 2048 -t rsa

Set no passphrase.  Still on the server, do this for each client, entering 
that client's root password.

ssh-copy-id -i /root/.ssh/id_rsa.pub root@client

This is equivalent to copying /root/.ssh/id_rsa.pub from the server to each 
client's /root/.ssh/authorized_keys file.  Note that both .ssh and 
authorized_keys must be readable/writable/executable by the user only, not 
group/other.

Regards,
Tyler
