Create disaster-recovery setup

Hi

I’m having an HA running on Raspberry PI 4 with all latest versions.
As I developed a lot to make my home intelligent I would like to have a spare configuration in case something is going deeply wrong.
What are my best options? I make a weekly full backup and copy it via Samba to my PC.
I have a Raspberry PI 3B as spare hardware. Buying a additional PI4 is an option when available again.

Thanks for sharing your thoughts.

Use this to make the backup and copy it off the system automatically each night:

Samba Backup: Create and store backups on a Samba share

Hey everyone! Just wanted to share a Home Assistant add-on with you which allows you to create snapshots and store them on a Samba share. You can check it out here: Samba Backup There are already similar add-ons available which upload snapshots to Dropbox or Google Drive, but I did not find anything that directly copies to a local NAS. So I created this one. Main Features: Automatically create snapshots (full or partial) and copy them to a Samba share Cleanup specified number of snapshots l…

How to restore a backup

This guide has been updated to use the much easier method introduced in version 0.116, if you are running an older version of Home Assistant than this you can check the edit history of this post for the old instructions. Note: this guide assumes you have copied the backup off your home assistant server before the problem occurred. So backup regularly and copy the backup eleswhere regularly. There are addons to do this automatically for you, see the list here: https://www.home-assistant.io/comm…

I have Google Drive Backups saving multiple scheduled backups, and I have Synology NAS sync that folder locally, so there’s always 2 copies of the snapshots available (3 if you count the original one on the HA drive). I use snapshots to revert back to a previous state if something gets messed up in HA.

In addition to keeping multiple snapshots, I make a periodic disk copy of the drive that HA runs on in case of a drive failure. I use either balenaEtcher or Win32DiskImager to create an image file of the entire drive. Save that image file to a second disk or clone/burn it to a backup drive you’d use to boot the entire OS.
