qr-backup takes file(s), and outputs a “paper backup”: a printable black-and-white PDF full of QR codes. To back up your file, print the PDF. The pile of paper in your hand is now a backup of the file.
If your file is lost, corrupted, deleted, etc, you can restore from your paper backup. qr-backup reads the QR barcodes using your computer’s webcam (or scanner) to get your file back.
This is free and public domain software.
Key Features
- Restore without qr-backup installed.
