The red lines (rsync) correspond to downloads we actively do using rsync (after being triggered). http://ftp.halifax.rwth-aachen.de/~cotto/rrd/debian-backports%23month.png http://ftp.halifax.rwth-aachen.de/~cotto/rrd/debian-cd%23month.png http://ftp.halifax.rwth-aachen.de/~cotto/rrd/debian-volatile%23month.png http://ftp.halifax.rwth-aachen.de/~cotto/rrd/debian%23month.png The graphical representation is not too helpful, but I also have the corresponding raw (Java-)RRD data.

Have a look at the graphs above. With 51 MBit/sec on average, Debian is not very demanding (although we're not ftp.de.debian.org, just ftp2).
