This article talks about using rsync and expect to automate the process on rsyc’ing your home directory to a central server via ssh without needing user input each time. It also keeps the system from being insecure (i.e. setting up a server/client trust without a passphrase) via storing the password in a variable for latter use. The administrator can then enter the password at his/her convience without waiting for the cron job execution time.
