No, it is the number of bytes currently stored in the backup volume named
wub-serv-web-day-0020.

The error "Connection reset by peer" means that the TCP connection between the
director and the client was closed forcibly without the director expecting it.

If this always happens 2 hours after the start of the job, then you probably
have a router or firewall between the director and the client that is limiting
the time for open connections.  You need to reconfigure that router to allow
longer connections.
