Creating a backup service container

1. Create a new container

This container should be a Linux-based container. The below docker-compose.yaml file is aa good example.

services:
  backup-container:
    image: ubuntu:22.04
    container_name: volume-backup
    command: sleep infinity
    volumes:
      # Mount all your existing volumes here
      # Example format:
      # - volume_name:/backups/volume_name:ro
      - volume1:/backups/volume1:ro
      - volume2:/backups/volume2:ro
      # Add all 20+ volumes following this pattern

• Note the volumes mounted to the /backups/<name> and are set as Read Only (:ro) These volumes will be used to automate the backup process using a script.

2. Check the Mounts

Start up the container, connect to it, and check the volumes are correctly mounted to /backups/<name>
