I didn't even realize this tool existed. I tried something like it awhile back, but it didn't work to my satisfaction (I don't remember why), so my awful, awful, awful workflow is to use the Google Takeout functionality to generate something like 8 .tar.gz files (50 gigabytes each), manually download each one (being prompted for authentication each time), and then rsyncing them over to my local server, and finally uncompressing them.
It's very lovely how much Google doesn't want you to exfiltrate your own data.
I wonder at which point I'll get annoyed enough to go through the effort of setting up immich. Which, naturally, will probably involve me re-working my local server as well. The yak's hair grows faster than I can shave it.
And how your albums, instead of being metadata, are folders, into which files are duplicated. It's literally shittily coded malicious compliance so they can pretend to let you have your data.
(Oh, you view your folders as important metadata that should be attached to a single copy of the image? Cool cool, write a bunch of code.)
