qr-backup is a program to back up digital documents to physical paper. Restore is done with a webcam, video camera, or scanner. Someday smart phone cameras will work.
I’ve been making some progress on qr-backup v1.1. So far I’ve added:
--restore, which does a one-step restore for you, instead of needing a bash one-line restore process
--encryptprovides password-based encryption
- An automatic restore check that checks the generated PDF. This is mostly useful for me while maintaining qr-backup, but it also provides peace-of-mind to users.
--instructionsto give more fine-tuned control over printing instructions. There’s a “plain english” explanation of how qr-backup works that you can attach to the backup.
--notefor adding an arbitrary message to every sheet
- Base-64 encoding is now per-QR code, each QR is self-contained.
- Codes are labeled N01/50 instead of 01/50, to support more code types in the future.
- Code cleanup of QR generation process.
- Several bugfixes.
v1.1 will be released when I make qr-backup feature complete:
- Erasure coding, so you only need 70% of the QRs to do a restore.
- Improve webcam restore slightly.
v1.2 will focus on adding a GUI and support for Windows, Mac, and Android. Switching off zbar is a requirement to allow multi-platform support, and will likely improve storage density.
