@mjtsai I have a very large Synology NAS (nearly 100 terabytes) and manually export originals from iPhoto once a quarter to it for safe-keeping. This has me thinking, it may be easier to have a Mac mini and just check the “keep originals” button instead but it’d need 2 terabytes of storage to do that. Can Photos libraries be located on an external drive? I’d then use CCCloner to push monthlies to my NAS. Added benefit, an M1 Mini would transcode 4K Plex content faster than my Synology.
