I thought I had a backup. I use the Gdrive add-on and it should have had a backup.
I didn’t have a backup.
Turns out when I moved from a Pi to Proxmox I didn’t set Gdrive add-on up properly, so it wasn’t making backups every 3 days like it always has.
Then I killed Proxmox. No idea what I did to kill it, I just tried to make my NAS VM have 4gb ram all the time instead of Ballooning from 1gb, and it never booted again.
So I had to start fresh. But while I’ve only been playing with VMs for a couple months my HA instance has been a work of love since Lockdowns and COVID times.
And now I’m starting again.
Now go and check your backup solution.
Just out of curiosity, I presume a full backup (inside HA, not of the VM itself) can be restored to a completely new HA VM and everything returns? Addons? Integrations? HACS?
Edit: and history?
Or… not?
Yes, based on my migration from a Raspberry Pi to a mini x86 pc. A full backup contains a complete snapshot of that moment and all your configuration, history, and all add-ons and their data. I think HACS came across too, though I can easily be misremembering.
The restore looked like it tried to do everything but my large database add on (PostgreSQL) gave it grief so I ended up restoring components separately. The backups did work overall though, and after a few reboots everything worked.
