His entire approach to storage of critical data was a disaster waiting to happen. Storing data on FAT-formatted USB drives and then transferring them to a Btrfs file system over Samba? Why? If you run an OS with first-class ZFS support and your files arrive on the platform as soon as possible over as few intermediaries as possible, the chances of such mishaps are greatly reduced. |

1. Camera stores images/videos on an SD card.
2. When the card is full, images are copied in the field on the USB drive. I imagine the user has a 128G SD card and multiple photo sessions will exhaust internal storage quickly, especially on a mac with 256G-512G SSD, hence an external drive. APFS may be used instead of FAT but then the drive won’t be readable on Windows or Linux. Mac doesn’t allow writes to an NTFS filesystem unless you buy a 3rd party driver of unknown reliability. I guess one can try to combine your linked guide with https://github.com/spl/zfs-on-mac to get ZFS on a USB drive but all of that is done at your own risk.
3. When the user gets home, they can plug the drive into a Linux/BSD machine with ZFS. They copy the files locally.
4. They proceed with their favorite workflow on another OS accessing files on ZFS over SMB. Bad writes from macOS over the network can still bork files on ZFS, though you can apply a readonly policy to RAW images.
Step 2 and 4 still look quite hard to work around for me. Bad SD card reader and bad RAM or bugs in any of the 3 machines are still a risk.
