I’ve been thinking of backing up a few dozen megabytes of my most important files in like QR codes or maybe something simpler like dual-parity data matrix with instructions in plain text and printed out FORTRAN code. Printed on long lived (waterproof?) paper with a laserjet. Along with plain text printouts of text and pictures.
Even thought of etching that on stainless plates or something.
Could be scanned with a smartphone or even decoded by hand (include an ASCII lookup table).
