The above is the reason for having a working area for rsync.
Yeah? So you always have effectively three copies of your data around?
I've never experienced a problem with just a local and remote copy of
data when using rsync, and it forms the basis of my backup system
(using link-dest, too).

Why three? You only need an unmodified version (for rsync) and a working version
(for clamd). The point is not to simply copy a file - the point is to copy only
the parts of the file that have changed since the most recent download. Rsync
can do either but bandwidth is not free so I prefer to do it the most efficient
way possible.
