You aren't happy with --detect-renamed ?

If you pass --stats, rsync will print a "Total transferred file size",
which is the total size of all regular files that would be
transferred.  The amount of data that rsync would actually send over
the network may be much less due to delta transfers, but there's no
way to predict this amount in advance.  As an alternative, you could
go ahead and attempt a real run but limit the total amount of data
sent by interposing a "head -c <nbytes>" into the connection.  If the
limit is hit before the run finishes, "head" will exit and the
connection will be dropped, allowing you to take corrective action; be
sure to use --delete-after to avoid premature deletion of destination
files whose source counterparts have been moved.  Reply if you would
like more help setting this up.
