Failed backups again

So, it's been working somewhat, well, my main backup replication that I need anyway, but others are still failing on a regular basis. Sometimes I can tell it must have been a network issue because sometime one replicate won't quite finish when another one starts and they'll both fail at exactly the same time.

I think I'll just start posting my weekly failures here.
My setup is one Pro4 at the office, the other at the owners house. No VPN tunnel, relying on P2P connectiong.
