My HA runs on a Yellow and I am about to upgrade the CM4 from a 2GB to a 8GB. It has a 256gb NVME. It seems I will have to boot the new module from a SD card and I am not sure if that wipes the NVME.

I will make a backup and move that to my desktop just in case but if I end up with a fresh install of HA, how do I go about bringing that external backup in to HA?

Thanks.

I'm supposed to respect my elders, but it's getting harder and harder for me to find one now.

I doubt it would wipe it. There's a tutorial on restoring from backup here.

I have HA running on Docker, with everything (config, automations, etc) checked into git daily. It works well. Runs on a Pi4. Next time I will get a larger computer, for cooling - Pi cases are terrible for cooling nvme SSDs, my case cooked one until it failed, now the case is split open in the cupboard with a heatsink on the nvme drive to help it stay cool. It's 48C now, previously it was around 90C.

I watched this video and he says the process will wipe the NVME 😒. If I have to do a fresh OS install and my data on NVME is wiped, how do I run the backup that will be on my PC? Can I put it on a thumb drive and get HA to back up from there?

You upload the backup from your PC and restore it. You can do it from the GUI.

It's extremely easy. I just spun up a new HA VM to double check and you get the option to restore on startup of a new instance. Just make sure you do a full backup.

Thats the bit I wondered about. Module arrives next week, fingers crossed.

You really don’t need to go through that sort of rigmarole for an HA OS installation docker is a little bit different.

It was one of the reasons I went to a VM instead of running everything in my docker environment.

I quite like the docker option. I'm running about eight containers to do various things on a single Raspberry Pi, and when I need to transfer to another machine it is much quicker - I do a Docker pull and then start everything with a script.

I ended up with Docker after having to reinstall everything a couple of times and got tired of all the dependencies and libraries and stuff for all the different things I run.

I get the use case - I’ve got 20 or 30 docker containers running on my homelab server as well as some VMs, including home assistant. I just found it much easier to run home assistant as a VM. I still have it’s influx db running as a docket though.

Having different ways to deploy is one of the nice things about the project.

Using the home assistant OS does have advantages, integrated with the store for example. I started off there but moved to Docker so I didn't need multiple raspberry pis.

I migrated my HAOS install from a pc to a rpi4 last week. Super simple. Backup first, then restore from backup. Everything was back up and running exactly the same.

It’s not really an issue when you have 12 cores and 24 threads available.

The newer low power mini pcs available now make raspberry pi’s a bit redundant for these types of applications if you run enough services. Once you buy cases and power supplies etc you can get pretty close to N100 money.

Absolutely, my next hardware for this kind of thing will be a compact computer of some kind, maybe Intel maybe ARM, but the key thing is the nvme drive needs to be properly cooled. Raspberry Pi cases are terrible for disk cooling.
