This tutorial describes how to do automated server backups with the tool rdiff-backup. rdiff-backup lets you make backups over a network using SSH so that the data transfer is encrypted. The use of SSH makes rdiff-backup very secure because noone can read the data that is being transferred. rdiff-backup makes incremental backups, thus saving bandwidth.
he problem is that SSH requires a password for logging in which is not good if you want to run rdiff-backup as a cron job. The need for a password requires human interaction which is not what we want. For example, to backup the directory /boot of server1.example.com, you would type rdiff-backup root@server1.example.com::/boot boot on your backup server (in this tutorial we name it backup.example.com) which would try to save server1.example.com's directory /boot in backup.example.com's directory boot.
