>connect your phone to your laptop, copy your photos off every month or so, and clear the phone storage. I actually can't believe this isn't the normal way people do things. People pay to let Google keep copies of all their photos?! And I mean, setting up your own self-hosted storage for all your photos is neat and stuff, but seriously, seems like overkill. One folder a year on my laptop / backup drive is sufficient for me.

Your suggested alternative of moving all photos to a laptop doesn't work for the people who prefer having all their photos accessible from their smartphone. That's the usable UI that the constant sync to cloud services gives them. The tradeoff is the cloud storage subsciption costs.

Also, transferring all photos to a laptop creates a single-point-of-failure if the laptop dies. Recovering photos becomes even more complicated when the internal SSD is encrypted with macOS File Vault or Windows BitLocker. Yes, photos in cloud storage isn't really a "true backup" in the 3-2-1 best practices sense but it's still more durable against catastrophic data loss than a single laptop.

The self-hosted Immich photo server is just one way to enable smartphone access to all photos and avoid paying for cloud storage. That's the reward for the "overkill" setup.
