Rsync
rsync is an open source utility that provides fast incremental file transfer. You can use the following script for the rsync

Here i am going to explain to rsync the /var/lib/mysql directory of the 192.168.0.125 to the backup server's path /backup1.For taht first of all we have to create the ssh key .you can use command ssh-keygen -t rsa -f mykey

mkdir /scripts
cd /scripts
ssh-keygen -t rsa -f mykey {press enterkey for the promoting )
vi backup.sh

   REMOTE_USER=root
   REMOTE_HOST=192.168.0.125
   REMOTE_PATH=/var/lib/mysql
   LOCAL_PATH=/backup1/
   KEY_FILE=mykey
   COMMAND=`which ssh`
   echo $COMMAND
   rsync  --delete -avvvz -e "$COMMAND -i $KEY_FILE"
   $REMOTE_USER@$REMOTE_HOST:$REMOTE_PATH  $LOCAL_PATH
                   chmod u+x backup.sh
   {be ensure the folder /backup1}is exist }
                   sh backup.sh
