incremental backup of files using shell script

Question

I have 10 files on remote server,I want to continuously check if there is any new file in the remote directory and if there is any new file it should be transferred to the local directory. I could write shell script to get the file but how do I get only the new files to be transferred,new files can be 1 to 10 in number Here is what i tried so far:

#!/bin/bash

user="abc"
ssh_host="host"
from_loc="/tmp/"
to_loc="/tmp/"
file="file.txt"

if ssh $ssh_host test -e $from_loc$file;
    then
        cd $to_loc
        sftp $user@$ssh_host <<EOF
cd $from_loc
get $file
bye
EOF
    else echo $file does not exist
fi

You can try rsync. It does what you want and more.

See this tutorial.
