For a moment, I use validation to make sure server side -NOT- empty
directory. For example:

#!/bin/sh

TEST="$(rsync -n rsync:/xxx.xxx.xxx.xxx/data/ | awk 'END {print NR}')"

if [ "$TEST" -gt "1" ]; then
    rsync -avPH --delete rsync:/xxx.xxx.xxx.xxx/data/ /mnt/DATA/
else
    exit 0
fi

Probably, your suggestion (option 1) is more handy to applied. Thank you.
