Creating a snapshot is not possible right now because the system is in freeze state

Hello,

here is my solution : :wink:

1-Install “auto_backup” from jcwillox https://github.com/jcwillox/hass-auto-backup
With this integration you can easely manage the “exclude” part of addon and folder (like /media and /usbstorage for me :wink: )
2-in the UI, integration, add “Auto Backup” integration, you will then have a “sensor.auto_backup”
3-Create a binary_sensor template:

  - platform: template
    sensors:
      auto_backup_template:
        friendly_name: "Auto Backup Template"
        value_template: >
          {% if is_state('sensor.auto_backup', '0') %}
            off
          {% elif is_state('sensor.auto_backup', '1') %}
            on
          {% endif %} 

4-install “custom-cards” https://github.com/custom-cards/button-card

5-create a custom_cards button: like this one with your binary_sensor.auto_backup_template: blink-animation

type: custom:button-card
color_type: card
entity: binary_sensor.auto_backup_template
name: Backup
state:
  - value: 'on'
    color: red
    icon: mdi:alert
    name: Backup in progress
    styles:
      card:
        - animation: blink 2s ease infinite
  - operator: default
    color: green
    icon: mdi:backup-restore
    name: No Backup in progress

and then you will know when your system is backing up :wink:

Enjoy!
