[CentOS] Rsync: how big is the traffic?

bandwidth actually is b/s, so your bandwidth is 23823.92 bytes/sec
as shown in the output from rsync.

As for the total file size you have uploaded or downloaded
this can very much differ from the actual file size on the system
because rsync compresses the data while in transfer.

On top of all this rsync uses up bandwidth for itself for
the administration for the process. So if you do not compress
you will have more data transfered simply because rsync needs
to find out about the files on both ends, further it needs to
create dirs etc.

so the total that was actuallty send an received is the sum
of both items above.
