Indeed, that's what I want to know: the really transferred bytes for
that host-to-host connection (from the remote host to my backuppc
server). Nothing concerning the backuppc pool...

Well, if I'd achieve something like this, I guess I would be collecting
*every single bit* (also commands issued and stuff like that).
For my purpose, it would be sufficient to know that I transferred a
total amount of 14 files, which sum up to 1034896 bytes. I tried to look
at the log files, but I don't understand how to distinguish between the
words like "pool", "same", "skip", "create"... If I could assume that
all the "create" ones are really transferred bytes, I'd be summing them
up with a simple bash script. But what about "pool" ones (I just imagine
that "skip" and "same" are really NO TRANSFERS)?
