That's the purpose of the --compare-dest option. Do the copy from a
source dir to an empty dir using the last-copied destination dir as the
arg for --compare-dest. Only changed files will be placed into the
destination. After ftping them to the live website, you can move them
into the last-copied destination dir and repeat. If you need to know
about deleted files, you'll need to do one additional copy after this
that only deletes files in the updated destination by using both the
--existing and the --ignore-existing options along with --delete (this
avoids doing any file transfers). If you make a note of what files get
deleted (by using a script to scan the output), you can duplicate those
deletions on the ftp site.

The following presumes A, B, and C are all in the same dir. Use full
paths as needed if they are not:
rsync -av --compare-dest=../B A/ C
# ftp each file from C to remote site and move it into B.
rsync -av --existing --ignore-existing --delete A/ B | tee dels
# perform deletions mention in "del" on remote site.
