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.

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

You can 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 your Ansible control node to meet the following requirements:

    • You are using Ansible version 2.14 or later.
    • You have installed the ansible-freeipa package.
    • The example assumes that in the ~/MyPlaybooks/ directory, you have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server.
    • The example assumes that the secret.yml Ansible vault stores your ipaadmin_password.
  • The target node, that is the node on which the ansible-freeipa module is executed, is part of the IdM domain as an IdM client, server or replica.

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 --vault-password-file=password_file -v -i ~/MyPlaybooks/inventory backup-my-server.yml

Verification

  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

You can 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 your Ansible control node to meet the following requirements:

    • You are using Ansible version 2.14 or later.
    • You have installed the ansible-freeipa package.
    • The example assumes that in the ~/MyPlaybooks/ directory, you have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server.
    • The example assumes that the secret.yml Ansible vault stores your ipaadmin_password.
  • The target node, that is the node on which the ansible-freeipa module is executed, is part of the IdM domain as an IdM client, server or replica.

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: true

  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: true
    # ipabackup_keep_on_server: true
    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 --vault-password-file=password_file -v -i ~/MyPlaybooks/inventory backup-my-server-to-my-controller.yml

Verification

  • 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

You can use an Ansible playbook to copy a backup of an IdM server from the IdM server to your Ansible controller.

Prerequisites

    • You are using Ansible version 2.14 or later.
    • You have installed the ansible-freeipa package.
    • The example assumes that in the ~/MyPlaybooks/ directory, you have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server.
    • The example assumes that the secret.yml Ansible vault stores your ipaadmin_password.

    $ cp /usr/share/doc/ansible-freeipa/playbooks/copy-backup-from-server.yml copy-backup-from-my-server-to-my-controller.yml
  4. Open the copy-my-backup-from-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. Set the ipabackup_name variable to the name of the ipabackup on your IdM server to copy to your Ansible controller.

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

      ---
- name: Playbook to copy backup from IPA server
  hosts: ipaserver
  become: true
  vars:
    ipabackup_name: ipa-full-2021-04-30-13-12-00
    ipabackup_to_controller: true
    ipabackup_controller_path: /home/user/ipabackups

  roles:
  - role: ipabackup
    state: present
  6. Save the file.

    $ ansible-playbook --vault-password-file=password_file -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: true

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

Verification

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

    [user@controller ~]$ ls /home/user/ipabackups
