#!/bin/bash

# Remote location
HOST=localhost.localdomain

# local directory where to store
PATHTOBACKUP=backup

# Timestamp is useful :-)
date=`date "+%Y-%m-%dT%H:%M:%S"`

# Just rsync notice the stdout will go to syslog
rsync -av $HOST:/home/ $PATHTOBACKUP/back-$date


Of course you need rsa keys and ssh properly configured :-)
