Ask HN: QR Codes Unsuitable for Storing Gigabytes and Beyond in Graphic Format?
Yes. QR codes are meant to store only a few kilobytes at most. They are not suitable for encoding gigabytes of data.
At perhaps 2KB per page, you'd need 524288 pages to store a 1GB. That's 1048 reams. Please just use an archival optical disk instead.
Even if the scheme using multiple QR codes in sequence rather than a single large code block. The paper backup implementations that use QR codes https://github.com/intra2net/paperbackup https://github.com/cyphar/paperback are only meant to be used for private key backup.

Horcrux: Split your file into encrypted fragments
> Q) This isn't really in line with how horcruxes work in the harry potter universe!
> A) It's pretty close! You can't allow any one horcrux to be used to resurrect the original file (and why would you that would be useless) but you can allow two horcruxes to do it (so only off by one). Checkmate HP fans.
Well the whole point of hurcruxes is to have backup in several places. This tool to backup your backups in several places is a much better use of the name https://github.com/chrispoole643/horcrux. Checkmate jesseduffield ;)
