Thanks to SeaweedFS, I've set up two replicas of the BSD Cafe's media. One is on a backup server (for disaster recovery purposes only, also containing the hourly zfs-autobackup backups), and the other is on a Raspberry Pi 4 running FreeBSD, which is one of my home backup servers - just one meter away from my desk.
I've also configured Nginx in a jail, so when I'm at home, the BSD Cafe's media is served directly from the local replica.
The performance is lightning fast.
