What is a long time? I’ve been running it more than a year, and the number of times it broke and the amount of time I had to invest into its quite high. You may be lucky, or I may be unlucky, but I’m just explaining my experience

We aware that Immich breaks one week and then the other week too

That’s interesting. Although I usually handle backups myself (to backblaze) and I never tested provider backup mechanism

Yes. In any case I will attach an external volume,which is easier to manage and relatively cheap. Thanks for pointing it out

It is not very hard. The problem is when they suddenly change an environment variable name or format, and you need to debug what is not working and why

Yes, you can. But will you be able to keep up with their tiring update cycle that forces you to redeploy every week?
