I'm super basic backup wise.
I run a rsync command that backs up the database dump and all the immich assets to a USB hdd. I do that every couple of days or when I think about it haha
I then back that USB drive up to another USB drive on my personal computer.
These drives are wd Reds and in USB enclosure.
My buddy has offered to host a off site backup but I have a toddler and as such 0 time.
I probably should look into some cold storage or something but shits expensive these days and I'm currently satisfied with where I am.
Knocks on wood
Additional context... I'm running Debian with mergerfs across like 8 drives. So my photos are spread across several drives in my /storage/photos folder. So In oder to lose everything all at once. It would have to be a flood or house fire or something..
