Backup Role

This Ansible role will set up tarsnap and tarsnapper to create encrypted backups regularly.

These backups are stored using tarsnap, which utilizes Amazon S3.

Learn more about Tarsnap, online backups for the truly paranoid.

Requirements

• A tarsnap account with funds
• This role is tested only on Ubuntu 16.04 (I can expand it to other platforms if there's interest; let me know by opening an issue)
• A tarsnapper configuration file located at templates/tarsnapper.yml.j2 in your playbook (how to write a tarsnapper config file)
• A tarsnap configuration file located at templates/tarsnap.conf.j2 in your playbook (how to write a tarsnap config file)

Role Variables

Notes

• If no tarsnap key file is found at files/{{ ansible_hostname }}.yml, a new key will be created using the backup__tarsnap_username and backup__tarsnap_password variables, and a new machine will be registered as {{ ansible_host }}.
• If a tarsnap key exists at files/{{ ansible_hostname }}.yml, that key will be used, and no new key or registration will happen.
• If the task to add the tarsnap apt key fails, it likely means the package's key has changed. Check the current key at https://www.tarsnap.com/pkg-deb.html, update it using the backup__tarsnap_apt_key variable, and please open an issue so I can update this role.

Dependencies

None.
