I love immich, too, but I have also ran into a lot of issues with syncing large libraries. The iPhone app will just hang sometimes.

Since the last major update to 2.0, it has gotten immensely better. Whereas before the app was hung for 30 seconds on startup and would only reliably sync in the foreground for my partner, it now just works. Can open, syncs in the background. Never had such issues on my phone, probably the size of your collection matters here.

Does it recover though, or do you end up in situations where your setup is essentially broken?

Like if I backup photos from iOS, then remove a subset of those from iOS to make space on the phone (but obviously I want to keep them on the cloud), and later the mobile app gets out of sync, I don't want to end up in a situation where some photos are on iOS, some on the cloud, but none of the devices has everything, and I have no easy way to resync them.

It won't recover unless I do something... sometimes just quitting the iPhone app and then toggling enabling backups works, but not always. I had to completely delete and reinstall the app once to get it to work, and had to resync all 45000 images/videos I had.

I have had the server itself fail in strange ways where I had to restart it. I had to do a full fresh install once when it got hopelessly confused and I was getting database errors saying records either existed when they shouldn't or didn't exist when they should.

I think I am a pretty skilled sysadmin for these types of things, having both designed and administered very large distributed systems for two decades now, but maybe I am doing things wrong, but I think there are just some gotchas still with the project.

Right, that's the kind of issues I am concerned about.

iCloud / Google Photos just don't have that, they really never lose a photo. It's very difficult for me to convince my family to move to something that may lose their data, when iCloud / Google Photos works and is really not that expensive.

		It has gotten more stable as I have used it for a while. I think if you want to do it, just wait until it is stable and you have a good backup routine before relying on it.

I have found adding the following four lines to the immich proxy host in nginx proxy manager (advanced tab) solved my immich syncing issues:

client_max_body_size 50000M;

proxy_read_timeout 600s;

proxy_send_timeout 600s;

send_timeout 600s;

FWIW, my library is about 22000 items large. Hope this helps someone.
