Ask HN: Backup/Store family stuff in 2024?

Hey HN, What's the simple way of backing family stuff up in 2024?

With stuff, I mean photos taken with iPhones, random documents, a place to put pre-iOS photos.

Access pattern would be more for trips down memory lane rather than automatic restoration.

Preferably I'd like some cloud syncing thing that also supports syncing to a physical drive every once in a while.

Currently my stuff is all spread out between iCloud, Flickr, dropbox and god knows where.

I'm happy to pay reasonable for it.

Any advice?
