Backup and restore feature

[berga]

Hi Jared,

did you think about restoring config/secrets/snapshot from a previous installation
or backing up before dismantle?

Especially for the restore, I think that's something that can be added. Doing a fresh install going from Debian 10 to 11 was tricky to get the backup restored from the command line, so I think that functionality could be useful to include.

my notes from restore:

1. copy backup file to HA server (or skip if file is already on server)

- hosts: all
  become: true
  tasks:
    - name: copy backup to pi
      copy:
        src: "/mnt/c/Users/jhamp/Downloads/Full Backup 2022-02-12 03_26_00.tar"
        dest: "/usr/share/hassio/backup/Full Backup 2022-02-12 03_26_00.tar"

2. need to reload backups so it pickups up the new backup file as being available to restore

root@rpi4-20220121:/usr/share/hassio/backup# ha backups reload
Command completed successfully.

3. we need to get the slug of the backup file to be able to restore it

root@rpi4-20220121:/usr/share/hassio/backup# ha backups list
backups:
- content:
    addons:
    - a0d7b954_nodered
    - core_mariadb
    - a0d7b954_vscode
    - core_mosquitto
    - core_check_config

  date: "2022-02-12T09:26:01.764980+00:00"
  name: Full Backup 2022-02-12 03:26:00
  protected: true
  size: 111.83
  slug: ffecdc5f
  type: full

4. now we can issue restore command - https://www.home-assistant.io/common-tasks/os/#creating-backup-using-the-home-assistant-command-line-interface

ha backups restore ffecdc5f

not sure if there are any prompts from the restore command.
