My concern with backing up iCloud Photos with anything but Apple Photos is that there are some proprietary formats like Live Photos and slow mo video for which exports are lossy. Also, Apple Photos stores all edits non-destructively, so 'flattening' the edits into a single file for export is also a lossy operation.

It seems like an obvious improvement for Time Machine to support full backups while using optimized storage on the primary system.

How about just turning off optimized storage and letting Time Machine do its job?

I have a 1.2T photo library. Carrying that around on my MacBook requires an $800 upgrade to the SSD.

Time Machine's job is to back up my data, it's not strictly to make a 1:1 copy of local storage. It should back up my cloud data too.

This. I don't understand why Apple don't have another checkbox beside the Download Originals to this Mac that reads 'Store Backup of Original Photos on Timemachine' This is all that's needed to solve the issue. I actually bought a Mac Studio, and a USB disk, just to be able to download originals of my photos for local backup, since a MBP is effetively a mobil limited device just like an iphone.

"I actually bought a Mac Studio"... "I don't understand why Apple don't " ... wait a minute

Could the first obvious improvement please be its speed? My god. The local Time Machine backup is slower on a 10gb network than Backblaze over the Internet. It isn’t even close.

I reinstalled my system and attempted for weeks to get Time Machine to complete a first backup. Every time I started it, the progress bar would fill up about 60% and then stall, and eventually kernel panic if the system was left idle for hours. Never happened before I reinstalled, though I have had it randomly decide the backup is corrupt and it has to start over. macOS deserves a better first-party backup feature.

Asking for anything out of Time Machine is a lost cause. It’s essentially a completed and legacy product.

I migrated to Linux + Pika Backup. For photos I use Ente Photos with their managed cloud storage plus a continuous export to my NAS.

Ente is surprisingly well integrated with iOS, you really don’t need to use Apple’s solution. It automatically backs up photos I take in the background.

I backup ~3-4GB a day with Time Machine to my local NAS and it takes less 10 minutes. Albeit it should take 30 seconds if it was maxing out the network speed.

In my experience migrating to another provider from iCloud, this hasn’t been a significant issue. Live Photos in particular are not really proprietary in the sense that they’re implemented in an extremely simple way that basically every photo tool understands. ~~Slow motion videos are also not proprietary, they’re just a plain video file.~~ <<< edit: I think I’m wrong about slow motion

I haven't looked into the implementation details, but Photos lets you adjust the section of the video that is played back in slow motion. I thought if you share a slow-mo video, it gets re-encoded to bake this in (i.e., one second at 240fps gets exported as four seconds at 60fps).

I’ve used this tool for years and it’s great. But it really saves just the raw data. You’d never get it back in to Apple Photos as nice as when you pulled it out. Metadata is missing. Live Photos come out as an image and a similarly named video. But I treat it as the emergency backup. If some Apple DC burns down or they ban my Apple ID for some reason, at least the photos still exist.

The most annoying thing for me is if you set the date for a photo, it gets stored externally rather than modifying the photo metadata. So when you switch platform, every photo which didn't originally have a captured at date ends up reset to the current day every time you move.

For edits, I don't care too much about just baking them in since it's unlikely I'm going back to old photos and want to undo the crop.
