Chapter 9. Backing up and restoring IdM servers using Ansible playbooks

Using the ipabackup Ansible role, you can automate backing up an IdM server, transferring backup files between servers and your Ansible controller, and restoring an IdM server from a backup.

This section covers the following topics:

9.1. Using Ansible to create a backup of an IdM server

The following procedure describes how to use the ipabackup role in an Ansible playbook to create a backup of an IdM server and store it on the IdM server.

Prerequisites

  • You have configured an Ansible control node that meets the following requirements:

    • You are using Ansible version 2.8 or later.
    • You have installed the ansible-freeipa package.
    • You have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server where you are configuring these options.
    • Your Ansible inventory file is located in the ~/MyPlaybooks/ directory.

Procedure

  1. Navigate to the ~/MyPlaybooks/ directory:

    $ cd ~/MyPlaybooks/
  2. Make a copy of the backup-server.yml file located in the /usr/share/doc/ansible-freeipa/playbooks directory:

    $ cp /usr/share/doc/ansible-freeipa/playbooks/backup-server.yml backup-my-server.yml
  3. Open the backup-my-server.yml Ansible playbook file for editing.
  4. Adapt the file by setting the hosts variable to a host group from your inventory file. In this example, set it to the ipaserver host group:

    ---
    - name: Playbook to backup IPA server
      hosts: ipaserver
      become: true
    
      roles:
      - role: ipabackup
        state: present
  5. Save the file.
  6. Run the Ansible playbook, specifying the inventory file and the playbook file:

    $ ansible-playbook -v -i ~/MyPlaybooks/inventory backup-my-server.yml

Verification steps

  1. Log into the IdM server that you have backed up.
  2. Verify that the backup is in the /var/lib/ipa/backup directory.

    [root@server ~]# ls /var/lib/ipa/backup/
    ipa-full-2021-04-30-13-12-00

Additional resources

  • For more sample Ansible playbooks that use the ipabackup role, see:

    • The README.md file in the /usr/share/doc/ansible-freeipa/roles/ipabackup directory.
    • The /usr/share/doc/ansible-freeipa/playbooks/ directory.

9.2. Using Ansible to create a backup of an IdM server on your Ansible controller

The following procedure describes how to use the ipabackup role in an Ansible playbook to create a backup of an IdM server and automatically transfer it on your Ansible controller. Your backup file name begins with the host name of the IdM server.

Prerequisites

  • You have configured an Ansible control node that meets the following requirements:

    • You are using Ansible version 2.8 or later.
    • You have installed the ansible-freeipa package.
    • You have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server where you are configuring these options.
    • Your Ansible inventory file is located in the ~/MyPlaybooks/ directory.

Procedure

  1. To store the backups, create a subdirectory in your home directory on the Ansible controller.

    $ mkdir ~/ipabackups
  2. Navigate to the ~/MyPlaybooks/ directory:

    $ cd ~/MyPlaybooks/
  3. Make a copy of the backup-server-to-controller.yml file located in the /usr/share/doc/ansible-freeipa/playbooks directory:

    $ cp /usr/share/doc/ansible-freeipa/playbooks/backup-server-to-controller.yml backup-my-server-to-my-controller.yml
  4. Open the backup-my-server-to-my-controller.yml file for editing.
  5. Adapt the file by setting the following variables:

    1. Set the hosts variable to a host group from your inventory file. In this example, set it to the ipaserver host group.
    2. (Optional) To maintain a copy of the backup on the IdM server, uncomment the following line:

       # ipabackup_keep_on_server: yes
  6. By default, backups are stored in the present working directory of the Ansible controller. To specify the backup directory you created in Step 1, add the ipabackup_controller_path variable and set it to the /home/user/ipabackups directory.

    ---
    - name: Playbook to backup IPA server to controller
      hosts: ipaserver
      become: true
      vars:
        ipabackup_to_controller: yes
        # ipabackup_keep_on_server: yes
        ipabackup_controller_path: /home/user/ipabackups
    
      roles:
      - role: ipabackup
        state: present
  7. Save the file.
  8. Run the Ansible playbook, specifying the inventory file and the playbook file:

    $ ansible-playbook -v -i ~/MyPlaybooks/inventory backup-my-server-to-my-controller.yml

Verification steps

  • Verify that the backup is in the /home/user/ipabackups directory of your Ansible controller:

    [user@controller ~]$ ls /home/user/ipabackups
    server.idm.example.com_ipa-full-2021-04-30-13-12-00

Additional resources

  • For more sample Ansible playbooks that use the ipabackup role, see:

    • The README.md file in the /usr/share/doc/ansible-freeipa/roles/ipabackup directory.
    • The /usr/share/doc/ansible-freeipa/playbooks/ directory.

    $ mkdir ~/ipabackups
  2. Navigate to the ~/MyPlaybooks/ directory:

    $ cd ~/MyPlaybooks/
  3. Make a copy of the copy-backup-from-server.yml file located in the /usr/share/doc/ansible-freeipa/playbooks directory:

    $ cp /usr/share/doc/ansible-freeipa/playbooks/copy-backup-from-server.yml copy-backup-from-my-server-to-my-controller.yml

    $ ansible-playbook -v -i ~/MyPlaybooks/inventory copy-backup-from-my-server-to-my-controller.yml
Note

To copy all IdM backups to your controller, set the ipabackup_name variable in the Ansible playbook to all:

  vars:
    ipabackup_name: all
    ipabackup_to_controller: yes

For an example, see the copy-all-backups-from-server.yml Ansible playbook in the /usr/share/doc/ansible-freeipa/playbooks directory.

Verification steps

  • Verify your backup is in the /home/user/ipabackups directory on your Ansible controller:
