Bedford Backup

Backup Bedford Machines #

This Ansible playbook performs automated backups of machines in the Bedford environment. It utilizes the BorgBackup tool for efficient and secure backups. The playbook also generates an SSH keypair for authentication and sets up a scheduled backup job using cron.

Play Variables #

• borgbackup_master: The master machine responsible for managing backups.

Play Tasks #

1. Ensure BorgBackup Installation

   This task ensures that BorgBackup is installed on the target machines using Homebrew.

   Module: community.general.homebrew

   - name: Ensure borgbackup is installed
     community.general.homebrew:
       name: borgbackup
       state: present
   

2. Generate Keypair

   This task generates an SSH keypair for authentication purposes.

   Module: community.crypto.openssh_keypair

   - name: Generate keypair
     community.crypto.openssh_keypair:
       path: /Users/{{ ansible_user }}/.ssh/borgbackup
     register: keypair
   

3. Print Public Key

   This task prints the generated public key to the console.

   Module: ansible.builtin.debug

   - name: "Print public key"
     ansible.builtin.debug:
       msg: "Public key: {{ keypair.public_key }}"
   

4. Copy the Client Script

   This task copies a client script template to the target machine, which is used for initiating backups.

   Module: ansible.builtin.template

   - name: Copy the client script
     become: true
     ansible.builtin.template:
       src: templates/borg_client.sh.j2
       dest: /usr/local/bin/borg_client.sh
       mode: 755
   

5. Create Backup Job

   This task sets up a scheduled backup job using the cron service. The backup job runs daily at 2:00 AM and executes the client script.

   Module: ansible.builtin.cron

   - name: Create backup job
     become: true
     ansible.builtin.cron:
       name: borg backup
       minute: "0"
       hour: "2"
       user: root
       job: /usr/local/bin/borg_client.sh
   

This playbook automates the process of setting up backups for machines in the Bedford environment, ensuring data safety and recovery. The SSH keypair generated adds an extra layer of security to the backup process, and the cron job ensures regular and consistent backups.
