Rdiff-Backup Script Ansible Role

Ansible Role automates backups by configuring an rdiff-backup script and list of servers to backup up from ansible inventory. It will install rdiff-backup on both the clients and server. On the server it creates a script and cron job to pull backups from clients periodically using rdiff-backup and ssh. It will also generate ssh keys on the server and add those to the client's authorized_keys file for passwordless ssh authentication. As servers are added and removed (marked present or absent) in ansible the backup list is automatically updated.

Requirements

This role should work on any popular Linux distribution for the client and backup server as long as rdiff-backup is available in the package repository.

rdiff-backup is included in recent versions of Ubuntu, Debian, and Fedora. For RedHat or CentOS 6 and 7 you'll need EPEL repos enabled.
