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.
