rsnapshot (master)

Ansible role to install and configure a rsnapshot master. It works in conjunction with the rsnapshot-slave role.

rsnapshot-master generates a SSH key for the "{{rsnapshot_master_host_user}}" system user which is by default root, and rsnapshot-slave is charged to set up the public key for a dedicated backup system user (with limited access rights) on remote hosts.

Running as non root user

This version allows you to run rsnapshot as a non-root user. In this case, you need to enable rsnapshot_master_host_user_uses_sudo if you want to perform localhost backup also.

Minimum Ansible Version: 1.4

Supported Platforms

• Debian
  • squeeze (6)
  • wheezy (7)
  • jessie (8)
  • stretch (9)
• Ubuntu
  • precise (12.04)
  • trusty (14.04)

Example (Playbook)

- name: Backup Master
  hosts: backup_master
  sudo: yes
  roles:
    - rsnapshot-master
  vars:
    - rsnapshot_config_backup:
        - name: LOCALHOST
          points:
            - [backup, /home/, localhost/]
            - [backup, /etc/, localhost/]
            - [backup, /usr/local/, localhost/]
        - name: REMOTE_1
          points:
            - [backup, 'backupuser@192.168.1.10:/home', remote_1/]
            - [backup, 'backupuser@192.168.1.10:/etc', remote_1/]
            - [backup, 'backupuser@192.168.1.10:/var', remote_1/]
        - name: REMOTE_2
          points:
            - [backup, 'backupuser@192.168.1.20:/home', remote_2/]
            - [backup, 'backupuser@192.168.1.20:/etc', remote_2/]
            - [backup, 'backupuser@192.168.1.20:/var', remote_2/]

192.168.1.10 and 192.168.1.20 hosts should be managed with the rsnapshot-slave role, as below:

- name: Hosts to backup
  hosts: remote_1:remote_2
  sudo: yes
  roles:
    - rsnapshot-slave
  vars:
    - rsnapshot_master_host: backup_master

See the rsnapshot-slave role for details about the slave configuration.
