All my Samba machines (DC's and member servers) are Debian/Ubuntu based
and being backed up via rsync. (Never had a reason to try rsyncd.) My
W7/W10 clients are all workstations with folder redirection so I do not
use Backuppc to back them up. (Just clonezilla images once a week for
them.)
Thanks to Adam Goryachev response from earlier, you have reiterated the
reason to do initial rsync backup on the local lan and then relocate the
machine. (I had read this in the past and forgotten that fact.) That is
easy to do, for me.
But, I am going to try adding the "-C" to the client sshpath just to
test and see what happens.
Thank for your help on this. I really appreciate it.
