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.
