I know there has been several posts from recent years about this, but none of the answers really addressed my question here.
Goal: To understand how Live Photos are stored so I can effectively back up (currently using Time Machine and SpiderOak with "download and store originals" turned on in iCloud Photo Library settings).
Question: It seems like all images (NOT including the "Live" .mov file) and videos are stored in
Photos Library.photoslibrary/masters, which is great, but when I want to find the "Live" part of each .heic file, I wasn't able to find them, and the .heic file doesn't seem to contain the video portion. So far, the closest I've come is by finding .mov files with completely unrelated names under
Photos Library.photoslibrary/resources/media/masters/ and it contains a very confusing folder structure and unrelated file names. This folder not only seems to contain the .mov files of the "live" photos, but also other jpeg files with unclear purposes.
Again, I'm simply trying to understand this to have peace of mind that when I back up
Photos Library.photoslibrary, all my Live Photos and edits, etc. are backed up. Furthermore, I'd like to be able to use these files (photos + "live" videos) across devices that may not run MacOS.
