That's a good start, but the most effective backup is manually carving the binary contents of a file onto steel plates that are many miles long.
Steel decays pretty quickly. The most durably data storage medium we've figured out is still ceramics
Metal can not be changed by Ruin
Maybe wrong community for this
Well there we go.
Honestly I just go for redundant drives and 3-2-1 backups, I remember looking at those pioneer bluray discs when they were announced and quickly deciding it wasn't worth the cost.
Your steel plate backup system sounds intriguing though - maybe it can be used as wallpaper? "What's that on your walls?" "My wedding photos"
The great part of that idea is that no one will think you're crazy when they see painstakingly carved rows of binary covering every surface of your home.
Will they know it's binary? Surely the dots would be so small it looks like noise unless there's an emerging pattern from file headers etc
