Does anyone have experience with running Apple Photos on an APFS Volume with a size quota to keep it from filling the whole SSD? I know this works in theory, but I’m curious if this works well or not.
Here’s the full situation:
We have a ~400GB Apple Photos library that is synced to iCloud Photos with my wife’s Apple ID. I have a Mac Mini with a 1TB data drive that keeps the full Apple Photos library in sync, which is then backed up with Time Machine, SuperDuper drive clones, and Backblaze. I also run Google Backup & Sync to sync the photos up to Google Drive Photos for an extra safeguard and so that I can view the family photos on my phone.
This all seems to work fine, except that I’d like for my wife to be able to run Apple Photos on her MacBook as well (the Mac Mini will still be the “home” for the photos and run the backups—her MacBook would just be for viewing/editing). In the past, we tried this with the Optimized Storage setting in Apple Photos turned on. But, this invariably still filled her hard drive, causing us to have to remove the Apple Photos library from that machine.
I have heard on some podcasts as well as in a few blog posts that you can create a new APFS Volume and set a quota on it. Putting the Apple Photos library on that and choosing optimize storage would thereby restrict how much space Apple Photos can hog on the system.
My question for you here is have you done this and have you encountered any issues that I should be aware of?
