With the possible exception of FTP (not sure if it can really be
scripted), this is fairly straightforward in shell script:

#!/bin/sh

#
# Find files newer than our timestamp file
#
FILES=`find /path/to/ftproot/ -anewer /var/run/timestamp`

#
# Note our new timestamp for the next run.
# There is an race condition here that I could probably solve given more time.
#
touch /var/run/timestamp

#
# Put them into a temp file
#
TARGET=`mktemp`
zip $TARGET $FILES

#
# Copy them to our target server via scp
# Give the zipfile a unique name, based on the current timestamp.
#
DATE=`date +%Y%m%d%H%M%S`
scp $TARGET user@host:files_${DATE}.zip

# The End.

Note that you really want to use ssh/scp instead of FTP.  It's much
easier to script, for one.
