You might consider initiating the rsync from the backup machines, and even possibly on a cron job basis.

Also, I would have been surprised if the uninstall/reinstall of sshd would have helped, as its clearly a network issue, not an ssh issue - at least the 'no route to host' (which is an unfortunate choice of wording - it really means something like "I get no answer to an attempt to contact this host.  Either the host isn't there, or there is no route to it".)

Thanks Rusty, Michael, and all ...

But I think I need a different solution than
"if all else fails" ;)

I have more than a dozen devices on my network
including four "back-up" computers to which I have
been using rsync to copy all of my most important
files on a regular basis. rsync is still working
fine to one of those back-up computers, but it
recently stopped working to 3 of the others and
this is the mystery I need to solve.
