I think the GP uses the MacMini as a "hack" to be able to back up the NAS cheaply with Backblaze's unlimited personal desktop backup offering (there's no official Linux client, imho): "Get peace of mind knowing your files are backed up securely in the cloud. Backup your Mac or PC just $5/month." And use their GUI program on MacOS and sync that remote NAS storage folder.
