9 disks in zraid3 holds my files, scrubs twice per month, ecc ram and cpu cache.
backup server galvanically disconnected, manually plugged in to synchronize, then scrub and shutdown, small window for catastrophe, chances of both servers getting killed at the same time is so small I'd probably be dead too.
main and backup servers are in two different locations (different power substations).
I just use rsync for doing the backup.
Family is connected to main fileserver. It snapshots once per week, so if they destroy something, I can get it back, it keeps two years of snapshots.
Once every 5 years I buy a new fileserver, the old one becomes the backup (assuming it is still healthy and not experienced any problems during it's service).
