Recover original files from Photos app, including original filenames?
Photos Version 5.0 (141.19.150) Catalina Version 10.15.4 (19E287) on a late 2013 iMac.
As I began preparation for setting up an automated rsync backup of the family photos I have run into a very disturbing aspect of Photos under Catalina: The original files in the library have been renamed to gibberish. ( In /Users/XXXXXX/Pictures/Photos Library.photoslibrary/originals)
By 'gibberish' I am meaning that to a human they are gibberish- "544BC43A-890E-4B4E-B05B-93066C4596A7" as a filename means absolutely nothing to me.
Why does the 'as-taken' filename matter so much to me?
1) While I like using Photos because of it's 'Apple ecosphere' aspect (pics are available on any Apple device), I don't like relying on Apple to safeguard my files. I lost a ton of stuff a bunch of years ago to an iPhoto migration, and won't let that happen again. My 'whole computer' backups are one way I backup, but I also want to have some redundancy for my family pictures and movies, as they are irreplaceable.
2) I need to back these images and movies up in a format that is NOT dependent on Apple's software. In the event of a system failure and I don't happen to have a few thousand dollars handy to buy a new Apple computer... I'll need the files stored with useful filenames to be able to use them in another OS environment.
3) They're MY content, MY files, and nobody (no software prompt) asked me if I wanted to rename all 71,500 of my files to meaningless strings.
4) For the same reasons that you don't want MS Word renaming your document to some gibberish string - it's not useful or desired, and can render a file unfindable.
In reading through many posts in the Apple Discussions about this renaming 'feature', I understand that I may be able to "Export Unmodified Original..." the entire library to a destination drive from within Photos and thereby recover the original filenames.
This is no small task for me, if it's true.
There are just under 70,000 images and a bit under 1500 videos in my library.
Exporting it all may take days, or weeks, if the 'normal' speed of exporting is what will happen. (By 'normal' I mean the usual amount time it takes to 'export' a single image of about 1.5MB from Photos to the remote HDD).
I am also concerned about application failure/crashing while undertaking such a huge task. I have had iPhotos (away back when) and then Photos (since switching to it years ago) sometimes behave erratically - where it's failed/crashed/locked up during some basic task or another. If it did so during an export of the entire library, I'd have no way to establish the last 'successful' export and begin again there. I'd have to restart the whole export.
Can anyone here in the Discussions advise me about this possible strategy of exporting to recover filenames, or tell me if there is a better way to recover all of my filenames?
Really want to resolve this, and am feeling quite sorely abused by Apple here.
What a complete PITA this is.
