It is supposed to be per IO operation, but between some of the parts of
rsync there might be some operations that are really taking that long.
There was a rsync patch put in not too many versions back which disabled
a timeout on one of the parts that tended to sit around for a long time.
60 seconds sounds pretty short though.

In what way is that not secure?

Are you using the latest version of rsync?
