Example Playbook

Simple Example:

- hosts: servers
  roles:
    - { role: while_true_do.rsnapshot }
  vars:
    - wtd_rsnapshot_config_shapshot_root: '/backup/'
    - wtd_rsnapshot_config_retains:
      - name: 'daily'
        value: '7'
    - wtd_rsnapshot_config_backups:
      - backup: /home/cinux
        target: home/

Advanced Example: rsnapshot is not designed to run multiple instance at the same time by using one config-file. Because of this its possible to set the wtd_rsnapshot_config_multi_enabled to true and configure multiple configurations of rsnapshot include systemd timers and services. Below you find a playbook with variable to get an illustration how the role works if you want to use multiple configurations. NOTE: Please only run this playbook in a test machine. Its for testing purpose.

- hosts: testmachine
  become: yes
  tasks:
    - name: create folders
      file:
        path: "{{ item }}"
        state: directory
      with_items:
        - /media/Share
        - /media/Audio
        - /media/Videos
        - /media/ISOs
- hosts: $VMIP
  become: yes
  roles:
    - { role: while_true_do.rsnapshot }
  vars:
    - wtd_rsnapshot_config_multi_enabled: true
    - wtd_rsnapshot_config_multi:
      - name: Backup_etc_systemd
        retains:
          - name: daily
            value: '7'
        backups:
          - src: /etc/systemd
            target: localhost/
        execStart: "/usr/bin/rsnapshot -c /etc/rsnapshot-Backup_etc_systemd.conf %i"
        logfile: "/var/log/rsnapshot-Backup_etc_systemd"
      - name: homes
        retains:
          - name: hourly
            value: '12'
            time: '*-*-* *:24:00'
          - name: montly
            value: '3'
            time: '1-*-* 00:00:00'
        backups:
          - src: /home/
            target: homes/
        snapshot_root: '/backup_home'
        execStart: "/usr/bin/rsnapshot -c /etc/rsnapshot-homes.conf %i"
        logfile: "/var/log/rsnapshot-homes"
    - wtd_rsnapshot_config_snapshot_root: /backup
    - wtd_rsnapshot_timer_time: "*-*-* 00:00:00"

After you have execute the playbook you can check with following commands:

systemctl list-timers | grep rsnapshot
ls -la /etc/rsnapshot-*

For each entry a separate configuration file gets created under /etc/rsnapshot-*. Additionally to this for each retains a timer will be created. And of course you can create for each retains a different time. This helps to run different retains at different times. Its also possible to set a default time by set wtd_rsnapshot_timer_time, but the time of a retain will overwrite it (can be seen in the above example by "Backup_etc_systemd"

Following variables, started with wtd_rsnapshot_config get overwritten by wtd_rsnapshot_config_multi if defined:

• config_version
• snapshot_root
• verbose
• loglevel
• lockfile
• timer

Testing

All tests are located in test directory.

Basic testing:

bash ./tests/test-spelling.sh
bash ./tests/test-ansible.sh
