Why Virtualize

you get full backups, snapshots, a build in monitor to debug. You can also better utilize the hardware. Not every service (very few imho) are feasible to run inside HAOS

easy troubleshooting (basically a build in monitor and keyboard), snapshots to test and then potentially revert things you otherwise would be too afraid to try. The ability to backup a whole machine and run other VMs/Containers and so on

I recommend running critical/unrelated things (adguard, unifi or bitwarden for example) or those that require flexibility outside of HAOS if you can as these will go down on OS updates. You can't do that with a bare metal HAOS install.

Some of my previous answers to why run HAOS virtualized. Just some of the benefits and reasons why I recommend it.

How to check HAOS space usage

The goal of this Article is to teach you how to find out what takes how much space on your HAOS system.
At the end of this article you should have an interactive way to explore your storage similar to this.

To check the recorder database size/stats I recommend the DBStats addon/container.

There's no question that many people successfully run SBCs and are happy with them but here's some of my biased reasons why I don't recommend ARM based SBCs like the pi, HA Green, HA Yellow, HA Blue, etc for running servers.

• They have a poor price performance ratio
• Some need a powered USB hub if you want to reliably use their USB ports, for example for a external SSD [2]
• Their internal storage sucks [1]. SD cards corrupt easily
• USB boot can be finicky and likely has to be configured:
  • https://www.home-assistant.io/faq/usb_boot/
• You need a HDMI adapter or USB C cable and a serial software to debug some of them
• You can only run specialized distros on them and hence can't easily boot just any live iso to troubleshoot or test something [3]
• You're limited in what you can run (ARM) and debugging tends to be harder

Proxmox VE tips

Just some tips I gathered over time. All in one easily reachable place so I can share it wherever I want.
Please note that unless you see a shebang (#!/...) these code blocks are meant to be copy & pasted.
Some of the steps will not work if you run part of them in a script and copy paste other ones.
