What is the state of your rsync process ? I'm pretty you enter the uninterruptible sleep state (D in ps)

Objet : rsync takes long pauses in xfer ?
I did some googling on this but did not come up with much. I'm using
rsnapshot which uses rsync, and I notice some pretty long pauses in
the xfers as you can see on this graph from "munin". THe machine in
question right at the moment is doing nothing but rsyncing (
rsnapshoting ) some 12T of NAS storage to local disk, so there is
nothing else going on at all.
You can see a couple of spots in the graph where it just drops to
nothing ( checking more closely you do see a very small bit of
Here is another graph from MRTG which records the traffic from the
switch port side. You can see around 2am it drops off pretty low,
then from about 4am til about 7am it drops even lower.
Is that normal? Or is this something I should ask on the rsnapshot
list (if there is one)?
I did find something in google about depending on the types of files
it can change xfer rate but not much detail.
