First of all you would need to enable ssh key authentication for enabling the password less access. Copy the public key of the source machine to the authorized_keys of the backup machine. Hope you know how to enable the SSH key authentication. Then execute this script as a cronjob.

#!/bin/bash -eu
#### Backup Server IP ###
BKP_SRV=”xxx.xxx.xxx.xxx″
### User name for rsync ###
USER=”root”

EMAIL=”user@example.com“
VAR=`ping -s 1 -c 1 $BKP_SRV > /dev/null; echo $?`
if [ $VAR -eq 0 ];then
rsync -av –delete $BACKUPDIR1 $USER@$BKP_SRV:$DSTDIR > /root/log/1.txt
rsync -av $BACKUPDIR2 $USER@$BKP_SRV:$DSTDIR > /root/log/2.txt
echo “Backup procedure completed successfully.”| mail -s “Backup Completed”$EMAIL
