I agree, I wouldn't want notification for evry non fatal errors as most
of the time, it's just some files being deleted or renamed during a
backup (and they'll be catched on the next backup).
I wrote a script which parse those Xfer errors, so I can be alerted if
the number of non fatal error is above a threshold. I use it with
Zabbix, and it's really helpful (those interested can take a look at
this:
